Cons
- Requires a neutral or second live wire
- Limited to electric baseboards and fan-forced heaters
Pros
- 7-day flexible scheduling
- Geofencing with automatic home and away
- ENERGY STAR certified
- Alexa ready
Cons
- C-wire power adapter required
- Limited with heating-only oil furnaces
Start With the Heating System
Mysa Smart Thermostat V2 for Electric Baseboard is designed for 120-240V electric baseboards and electric fan-forced heaters. It requires one neutral wire or a second live wire, so the existing wiring matters before you remove the current thermostat.
Honeywell Home T5 Smart Wi-Fi Thermostat is aimed at most heat and cool oil furnace systems, with an important limitation: a heating-only oil furnace needs a C-wire. Its C-wire power adapter requirement also deserves attention during the compatibility check.
If your home uses electric baseboards, start with Mysa’s system requirements. If it uses a compatible furnace setup, the Honeywell Home model offers a different route to location-based temperature control. For broader smart-energy ideas, see the Smart Thermostats category.
Check Wiring First: A thermostat that does not match the home’s voltage or wiring can leave the heating system unusable. Turn off power and confirm the system type before handling thermostat wires.
Geofencing Versus a Fixed Schedule
Geofencing uses your smartphone’s location to help recognize when you are away and when you return. Honeywell Home T5 lets you choose between seven-day scheduling and location-based temperature control, so it suits households whose routines change often as well as those with predictable weeks.
Mysa includes scheduling and geofencing, along with remote heating adjustments from an Android or iOS device. That combination can be useful when you want a programmed routine but still need to change the temperature while away.
| Control style | Key requirement | Best fit |
|---|---|---|
| Geofencing | Smartphone location | Changing routines |
| Scheduling | Planned weekly routine | Predictable routines |
| Remote adjustment | Android or iOS device | Away-from-home changes |
Neither approach removes the need to confirm compatibility first. Geofencing is a control feature, not a replacement for correct wiring or a suitable heating system.
Smart-Home Support and Energy Information
Mysa supports Apple Home, Alexa, and Google, which may matter if your household already uses one of those platforms. Its touchscreen, humidity sensor, and phone controls add several ways to adjust the heating system.
Honeywell Home T5 works with Alexa and provides monthly energy reports plus personalized tips on reducing energy use. It is also ENERGY STAR certified, and the manufacturer states that frequent scheduling saved customers between 8 and 16% on heating and cooling bills, while actual results vary with consumption.
ENERGY STAR is an efficiency certification, not a promise of identical savings in every home. You can also ask your energy provider about rebates or demand response programs. The Smart Energy and Climate Control section is useful if you are considering related household controls.
FYI: Geofencing means temperature control based on a phone’s location. It is different from a fixed seven-day schedule, which follows programmed times instead.
Installation Details That Affect the Choice
Mysa is described as installing in 15 minutes or less with step-by-step online guides and videos, but the voltage and wire requirements still come first. A quick installation claim does not make an incompatible electrical system suitable.
Honeywell Home T5 requires you to check compatibility and determine whether a C-wire power adapter is needed. If you are uncertain about the wiring, stop before connecting anything and seek qualified electrical help.
Expert Examined
From Ray Okafor
I keep seeing thermostat decisions made from the app features first, while the wiring is treated as an afterthought. I would identify the heater type and available wires before comparing geofencing controls, because that single check can eliminate the wrong model early.

Which Thermostat Fits Your Home
I would point you to the Mysa Smart Thermostat V2 for Electric Baseboard if your home has 120-240V electric baseboards or electric fan-forced heaters and the wiring includes one neutral or a second live wire. Its humidity sensor, touchscreen, scheduling, geofencing, and compatibility with Apple Home, Alexa, and Google make it the more natural match for that specific electric-heating setup. I would also value its Android and iOS remote controls when you need to adjust heating away from home.
I would choose the Honeywell Home T5 Smart Wi-Fi Thermostat for a compatible heat and cool oil furnace system, provided the C-wire requirement is satisfied. It gives you a choice between seven-day scheduling and location-based control, plus monthly energy reports and ENERGY STAR certification. If your routine changes frequently, geofencing may be more convenient; if your week follows a pattern, scheduling may be simpler.
Before either purchase, I would write down the heating system type and inspect the existing thermostat wiring. That short preparation is more useful than choosing a control style based only on the app or touchscreen.
The Bottom Line
The mistake most buyers make with geofencing thermostats is treating smartphone control as proof of compatibility. Mysa is for specified high-voltage electric heating, while Honeywell Home T5 has its own system and C-wire requirements.
If you only do one thing first, identify the heater type and wiring at the thermostat. Then choose between geofencing and a fixed schedule based on how reliably your household comes and goes.
FAQs
Mysa is specified for 120-240V electric baseboards and electric fan-forced heaters. It requires one neutral wire or a second live wire, so confirm those requirements before installation. Not necessarily. Honeywell Home T5 lets you choose seven-day scheduling or location-based temperature control, while Mysa includes both scheduling and geofencing. Mysa requires one neutral or a second live wire for its specified high-voltage systems. Honeywell Home T5 requires checking compatibility and may need a C-wire power adapter. ENERGY STAR certification indicates the product meets the program’s efficiency criteria. It does not guarantee the same household savings for everyone, since actual results vary with consumption.Which thermostat type suits electric baseboard heat?
