Choosing among the best heat pump monitoring systems depends on what you need to see. The Emporia Vue 3 is my pick for tracking a heat pump’s electricity use at the circuit level, while the YoLink Thermostat 2 adds schedules and remote control for a compatible two-stage system. For a straightforward wall control with temperature and humidity readings, the Garystat keeps things simple. Those options serve different jobs: an energy monitor can show electrical consumption, while a thermostat mainly tracks room conditions and controls heating and cooling.

I ranked these five around their usefulness for understanding or controlling a heat pump, along with compatibility details and the effort required to get started. The Honeywell Lyric T6 Pro models bring Wi-Fi programming and smart home features, but the available product information is uneven: one listing has few system details, and the other specifies compatibility but offers less information about monitoring. Read the wiring and system requirements closely, since a thermostat that cannot match your equipment will not be a useful upgrade.

Key Takeaways
Emporia Vue 3 is the only option here built to monitor electricity use by circuit, which makes it the clearest choice for tracking a heat pump’s energy draw.
YoLink Thermostat 2 pairs two-stage heat pump control with schedules, app access, and support for external sensors, but it requires a C-wire and a separately purchased hub.
Garystat displays temperature and humidity and can run without a C-wire, making it a simpler choice for buyers who want local thermostat readings rather than remote smart controls.
Honeywell Home Lyric T6 Pro TH6220WF2006 lists Alexa and Apple HomeKit support plus compatibility with up to two heat and one cool heat pump systems; its listing calls the display manual.
Thermostat readings are not energy measurements. If you want to see circuit electricity use, the Emporia fills a different role from all four thermostat options.

More Details on Our Top Picks
Emporia Vue 3 Home Energy Monitor with 16 Circuit Sensors
The Emporia Vue 3 is the strongest match here if “monitoring” means finding out how much electricity a heat pump uses. Its 16 included branch sensors let owners track selected circuits alongside whole-home consumption, so the heat pump’s electrical demand can be separated from other household loads. That is a different kind of visibility from the Garystat’s temperature and humidity readout or the YoLink thermostat’s app control: Emporia measures electricity rather than managing the room setpoint.
Its reporting options can help buyers spot changes in consumption and connect household use with solar or net metering. The stated ±2% accuracy gives a concrete reference for circuit readings, and cloud data export can suit someone who wants to examine trends beyond what a wall thermostat shows. The tradeoff is installation and connectivity: sensors go in the electrical panel, and the monitor needs 2.4 GHz Wi-Fi and an internet connection. That is a more involved setup than replacing a thermostat.
Emporia’s short-interval data also has limits. One-second readings are retained for three hours and are available only while the app is open; one-minute readings last seven days, while hourly data is retained indefinitely. For monitoring a heat pump over seasons, the hourly history may be more useful than moment-by-moment graphs, but anyone expecting a permanent second-by-second record should look elsewhere. Some electrical configurations also need an additional sensor. Against the Honeywell Lyric models, Emporia is far more explicit about energy measurement; against YoLink, it measures consumption while YoLink handles heating schedules and controls.
Pros:- Tracks whole-home and individual circuit electricity use
- Includes 16 branch sensors and supports solar and net metering
- Provides live reporting, notifications, automations, and cloud data export
- Lists ±2% accuracy and keeps hourly data indefinitely
Cons:- Requires circuit-panel installation, 2.4 GHz Wi-Fi, and internet access
- One-second readings have limited retention and require the app to remain open
- Some system configurations need an additional sensor
Best for: Homeowners who want to track their heat pump’s circuit-level electricity use, especially alongside whole-home consumption or solar generation.
Not ideal for: Renters, buyers who cannot access or modify their electrical panel, or anyone seeking a thermostat with direct heating schedules and temperature control.
- Circuit sensors:Sixteen 50A branch sensors included
- Supported systems:Single phase, single-split phase, and 2-wire; select 3-wire and 3-phase 4-wire Wye systems with an additional 200A sensor
- Accuracy:±2%
- Connectivity:2.4 GHz Wi-Fi and internet connection required
- Data retention:1-second data for 3 hours; 1-minute data for 7 days; 1-hour data indefinitely
- Installation:Circuit panel with clamp-on sensors
- Certifications:UL Listed and CE Listed
- Warranty:1 year
Our verdict“For buyers focused on heat pump electricity consumption, the Vue 3 gives the clearest energy picture in this group, provided panel installation is practical.”
YoLink Thermostat 2 Smart Heat Pump Thermostat (YS4004)
For someone who wants to control a compatible heat pump remotely, YoLink’s Thermostat 2 offers more active management than the Emporia monitor. It supports two-stage heat pump heating and cooling, schedules, ECO mode, app access, and voice control. That makes it suited to households looking to adjust operation around their routines. It does not provide the circuit-level electricity accounting that puts Emporia first, so the two are complementary rather than interchangeable.
The standout detail is YoLink LoRa connectivity, with a stated range of up to a quarter mile under the listed conditions. This may appeal where ordinary wireless coverage is a concern, though the thermostat still depends on a YoLink hub, which is sold separately. The external sensor support—up to two YS8007-UC sensors—can give buyers a way to incorporate readings beyond the thermostat’s own wall location. The product details do not specify that these sensors are included.
Compatibility is the gate. The system needs a 24 VAC setup with a C-wire, while the Garystat can run on two AAA batteries without one. Buyers should check their wiring before choosing YoLink, then account for the separate hub in planning the installation. Compared with the Honeywell Home Lyric T6 Pro listing, YoLink provides clearer information about dual-stage heat pump support and sensor expansion. Its advantage is smart control and range; its costs are added hardware and stricter wiring requirements.
Pros:- Supports two-stage heat pump heating and cooling
- Offers app control, schedules, ECO mode, and voice integrations
- LoRa connectivity has a stated range up to one quarter mile
- Supports up to two compatible external sensors
Cons:- Requires a compatible 24 VAC system with a C-wire
- YoLink hub is required and sold separately
- Does not provide the circuit electricity tracking offered by Emporia
Best for: Owners of compatible two-stage heat pumps who want app scheduling, voice control, and the option to add remote sensors.
Not ideal for: Homes without a compatible 24 VAC C-wire, or buyers who want a complete setup without buying a separate hub.
- Model:YS4004
- HVAC compatibility:Heat pump; 2-stage heating and cooling
- Connectivity:YoLink LoRa; hub required and sold separately
- Wireless range:Up to 1/4 mile (up to 2,034 feet)
- Sensor support:Up to two YS8007-UC sensors
- Power and wiring:24 V corded electric; C-wire required
- Control methods:App, voice, and remote control
- Display:4.52-inch LCD
- Certification:UL
Our verdict“Choose YoLink when remote control and scheduling matter more than circuit-level energy data and your wiring supports it.”
Garystat Non-Programmable Heat Pump Thermostat with Temperature and Humidity Monitor
The Garystat is a straightforward choice for buyers who want to see indoor temperature and humidity at the thermostat and adjust a heat pump manually. It supports two heating stages and one cooling stage, with a large green-backlit display and separate buttons. Compared with YoLink, it gives up schedules, app access, voice control, and remote sensors; in return, its listed setup is simpler and it can operate without a C-wire.
Its temperature and humidity readings make it more informative at the wall than a basic control that displays only a setpoint. The stated ±1°F control precision and three-minute compressor delay protection add useful operating details, while 24 VAC or two AAA batteries give some flexibility when wiring is limited. This is still a thermostat, not an energy monitor: it cannot tell the buyer how many kilowatt-hours the heat pump consumed. For that, Emporia is the only clearly specified circuit-monitoring option in this lineup.
Compatibility deserves careful attention. Garystat supports heat pumps and certain conventional gas, oil, or electric furnaces, but it is not for electric baseboard or other line-voltage equipment, and it is not compatible with RV thermostats. It also lacks the programming found on both Honeywell Lyric options and YoLink. That makes it a more sensible fit for a buyer who values a legible local display and uncomplicated manual control than for anyone who wants to automate temperature changes or inspect system performance remotely.
Pros:- Monitors both indoor temperature and humidity
- Large backlit LCD with separate buttons
- Can operate on 24 VAC or two AAA batteries without a C-wire
- Lists two heating stages, one cooling stage, and compressor delay protection
Cons:- Non-programmable and lacks listed app or remote control
- Not compatible with line-voltage systems or RV thermostats
- Does not measure heat pump electricity consumption
Best for: Heat pump owners who want a readable local temperature and humidity display, manual controls, and an option that does not require a C-wire.
Not ideal for: Buyers seeking app monitoring, remote control, programmable schedules, circuit energy readings, or support for line-voltage and RV systems.
- Type:Non-programmable thermostat
- Heating and cooling stages:2 heating stages; 1 cooling stage
- Compatible systems:Heat pumps and compatible conventional gas, oil, or electric furnaces
- Temperature accuracy:±1°F
- Monitoring:Temperature and humidity
- Power:24 VAC or 2 AAA batteries
- C-wire:Not required
- Compressor delay protection:3 minutes
- Warranty:2 years
Our verdict“Garystat suits buyers who want clear readings and manual heat pump control, but it offers less automation than YoLink or Honeywell.”
Honeywell Home Lyric T6 Pro Wi-Fi Programmable Thermostat
This Honeywell Home Lyric T6 Pro has the more useful heat pump details of the two Lyric listings. It specifies support for up to two heat and one cool heat pump, plus compatibility with up to two heat and two cool conventional systems. Wi-Fi app control and Amazon Alexa and Apple HomeKit support give it a clear smart home role. Compared with the Garystat, it adds remote app control and programming; compared with YoLink, the supplied details do not describe LoRa range or support for external sensors.
For a buyer focused on monitoring, its value is mainly in remote temperature control and smart home integration rather than energy data. The listed screen type is “Manual,” and the available product information does not provide details such as temperature accuracy, humidity measurement, or energy reporting. I would not treat its Wi-Fi connection as proof of circuit-level heat pump monitoring: Emporia is the more appropriate pick for that specific job.
The model is a wall-mounted thermostat with AC/DC power and two AA batteries listed. That battery requirement is worth checking against the intended installation, particularly if the goal is to replace a thermostat and reduce ongoing attention to power. Its stated heat pump staging makes it a more grounded choice than the TH6320WF2003 listing, which offers fewer compatibility details. Still, buyers should confirm their system wiring and exact equipment match before deciding; the available description does not resolve every installation question.
Pros:- Lists compatibility with heat pumps up to 2 heat/1 cool
- Provides Wi-Fi and app control
- Supports Amazon Alexa and Apple HomeKit
- Also lists compatibility with conventional systems
Cons:- Two AA batteries are required according to the listing
- Display is described as manual, with limited detail about its interface
- Does not list circuit-level energy monitoring or humidity measurement
Best for: Heat pump owners who want a programmable Wi-Fi thermostat with listed Alexa and Apple HomeKit compatibility and support for up to two heat stages.
Not ideal for: Buyers who need circuit energy consumption data, humidity monitoring, or a fully detailed account of wiring and system compatibility before purchase.
- Model:TH6220WF2006
- System compatibility:Up to 2 heat/1 cool heat pump or 2 heat/2 cool conventional
- Connectivity:Wi-Fi
- Smart home compatibility:Amazon Alexa and Apple HomeKit
- Control method:App
- Power:AC/DC; 2 AA batteries listed
- Display:Manual; 11.4 cm screen listed
- Dimensions:1.09 × 4.06 × 4.06 inches
- Mounting:Wall mount
Our verdict“The TH6220WF2006 is the more clearly specified Lyric choice for smart heat pump control, though Emporia remains the better fit for energy tracking.”
Honeywell Lyric T6 Pro Wi-Fi Programmable Thermostat
The TH6320WF2003 earns its place as a compact Wi-Fi thermostat option, but the listing provides less information for a heat pump buyer than the other thermostats here. It confirms programmable Wi-Fi control and dimensions of 4.09 × 4.09 × 1.06 inches. Unlike the TH6220WF2006 listing, it does not state heat pump stage compatibility or name Alexa and Apple HomeKit. That makes it harder to recommend for a specific system without checking the exact model documentation and wiring requirements.
Its likely appeal is to a buyer who already knows this model matches their equipment and wants a small, programmable wall thermostat with Wi-Fi. In this roundup, YoLink has clearer two-stage heat pump specifications and external sensor support, while Garystat has explicit local temperature and humidity readings. The TH6320WF2003 product details do not list those monitoring capabilities, so I would not choose it for energy tracking or for extra room-condition information.
The model is listed as made in the United States, and its compact dimensions may matter when replacing an existing control in a tight spot. Those details do not answer the key fit questions, however. The description does not specify stages, power, sensors, or smart home integrations. That is why it ranks fifth: the stated Wi-Fi and programming are useful, but the evidence for heat pump monitoring and compatibility is thinner than for the other entries. Confirm the exact system match before buying.
Pros:- Offers Wi-Fi connectivity and programmable operation
- Compact listed dimensions may suit a replacement installation
- Specific model number is provided
- Made in the United States according to the listing
Cons:- Available details do not specify heat pump stage compatibility
- No humidity, external sensor, or circuit energy monitoring is listed
- Smart home integrations and power requirements are not specified
Best for: A buyer who has confirmed TH6320WF2003 compatibility and wants a compact, programmable Wi-Fi thermostat.
Not ideal for: Buyers who need clearly stated heat pump staging, humidity or circuit energy monitoring, or named voice assistant compatibility.
- Model:TH6320WF2003
- Type:Programmable Wi-Fi thermostat
- Connectivity:Wi-Fi
- Dimensions:4.09 × 4.09 × 1.06 inches
- Made in:United States
- Heat pump stages:Not specified in the supplied product details
- Monitoring features:Not specified in the supplied product details
Our verdict“Consider the TH6320WF2003 only after confirming exact system compatibility, since its listing offers fewer heat pump details than the other thermostat picks.”
How We Picked
I ranked these options by how directly they help a homeowner monitor or manage a heat pump. My first distinction is between measuring electricity use and controlling room temperature. The Emporia Vue 3 uses clamp-on sensors in the circuit panel to report whole-home and individual circuit consumption. The thermostats instead report or control conditions at the wall, and their usefulness depends on matching the heat pump’s stages, wiring, and power requirements.
I also weighed the practical path to installation. Circuit-panel monitoring calls for a compatible panel, Wi-Fi, and internet access; thermostat upgrades call for checking the system wiring and equipment compatibility. A feature only helps if it can be used with the installed setup. That is why the YoLink’s separate hub and C-wire requirement matter, and why the Garystat’s support for two heating stages and one cooling stage should be compared with the home’s actual configuration.
Finally, I considered how much useful detail the product information provides. Emporia, YoLink, and Garystat include specific monitoring or system details. The Honeywell listings provide less complete evidence for heat pump monitoring, so I placed them behind the more clearly specified choices. The two Lyric models also differ: the TH6220WF2006 listing names heat pump stages and smart home compatibility, while the TH6320WF2003 listing mainly confirms Wi-Fi programming and dimensions. This order favors clear fit and purpose over a feature count.

Factors to Consider When Choosing Best Heat Pump Monitoring Systems
Before choosing a heat pump monitoring system, decide whether you want to measure electricity, read room conditions, or change how the equipment runs. These products cover different parts of that decision, so I would start with the task rather than the app or display.
Decide what you want to monitor
Electricity use and room conditions are different measurements. Emporia Vue 3 tracks consumption at the panel and can help isolate a heat pump circuit. A thermostat such as Garystat or YoLink reports or controls conditions at the wall. A thermostat’s Wi-Fi connection does not by itself mean it measures the heat pump’s electrical use. If energy consumption is the priority, choose a circuit monitor; if setpoint control is the goal, compare thermostats.
Match the thermostat to the heat pump
Check the system’s heating and cooling stages against the thermostat’s stated support. YoLink and Garystat both list two heating stages and one cooling stage, while the Honeywell Home TH6220WF2006 lists support for up to two heat and one cool heat pump. The TH6320WF2003 details supplied here do not specify stages. Confirm the exact model and equipment combination before installation, especially if the heat pump uses auxiliary heat or a less common configuration.
Check wiring and power
Wiring can narrow the choices quickly. YoLink requires a 24 VAC system with a C-wire and a separate hub. Garystat can run from 24 VAC or two AAA batteries and does not require a C-wire. The Honeywell Home listing names AC/DC power and two AA batteries, while the TH6320WF2003 details do not describe its power requirements. For Emporia, the relevant check is access to a compatible electrical panel and the required Wi-Fi and internet connection.
Think about data history and sensors
For longer-term electricity tracking, Emporia retains hourly data indefinitely, while its one-minute and one-second records have shorter retention periods. YoLink supports up to two compatible external sensors, which may help extend sensing beyond the thermostat’s wall location; confirm whether those sensors are separately purchased. Garystat measures temperature and humidity at the thermostat. The Honeywell listings provide less information about additional sensors or historical monitoring, so compare the exact product documentation if those details matter.
Set expectations for installation
A thermostat replacement involves identifying wiring and matching terminals to the equipment. Panel monitoring involves access to the electrical panel and placing clamp-on sensors around conductors. Those are different installation tasks with different compatibility checks. If the wiring or panel layout is unfamiliar, consult a qualified HVAC or electrical professional. In either case, verify the system type and model requirements before choosing based on convenience features alone.
Frequently Asked Questions
What is the difference between a heat pump monitor and a smart thermostat?
A circuit energy monitor measures electrical consumption, often at the whole-home and individual circuit level; Emporia Vue 3 is the option in this roundup designed for that job. A thermostat measures or controls temperature at the wall and may add schedules, app access, or humidity readings. A smart thermostat can help manage operation, but the listed thermostat features here do not provide the same circuit-level consumption data.
Can the Emporia Vue 3 show how much electricity my heat pump uses?
It can monitor individual circuit electricity use when its sensors are installed on the relevant circuits in a compatible panel. The product includes 16 branch sensors and reports whole-home as well as circuit data. Confirm the panel configuration and sensor requirements first; some supported system arrangements call for an additional 200A sensor, and the monitor also requires 2.4 GHz Wi-Fi and internet access.
Which thermostat in this roundup works without a C-wire?
Garystat is the one that explicitly lists operation without a C-wire, using either 24 VAC or two AAA batteries. YoLink requires a C-wire on a compatible 24 VAC system, and the Honeywell Home TH6220WF2006 lists AC/DC power and two AA batteries without fully describing its wiring needs here. Check the exact thermostat installation documentation against the wires at your wall before purchase.
Does the YoLink Thermostat 2 include everything needed for remote control?
No. The supplied details say a YoLink hub is required and sold separately. The thermostat also requires a compatible 24 VAC system with a C-wire. It supports schedules, app and voice control, and up to two compatible external sensors, but buyers should check which sensors are included or need to be purchased separately.
Which option should I choose if I want temperature and humidity readings?
Garystat explicitly lists both temperature and humidity monitoring on its thermostat display, alongside manual control. The YoLink listing describes its LCD and support for separate sensors, but does not list built-in humidity measurement in the supplied details. For circuit electricity use rather than room conditions, Emporia is the more direct choice; the two types of readings answer different questions.
Conclusion
If your main question is how much electricity the heat pump uses, I recommend the Emporia Vue 3, assuming panel access and Wi-Fi are available. For remote control and schedules on a compatible two-stage system, YoLink is the strongest fit if you have a C-wire and are prepared to add its hub. Choose Garystat for a simple local temperature and humidity display without a C-wire. The Honeywell Home TH6220WF2006 suits buyers who want Wi-Fi app control and Alexa or HomeKit integration, while the TH6320WF2003 is best approached cautiously until its exact heat pump compatibility is confirmed. Match the product to the kind of information or control you want, then verify wiring and system stages before installation.
