Mysa Smart Thermostat LITE For Electric Baseboard Heaters 240V
High‑Voltage Focus: Mysa is explicitly built for high/line voltage electric heating systems including 120–240V electric baseboards and fan‑forced heaters. The product page warns it does not support low-voltage systems or two‑wire installations.
Wiring And Installation: Requires at least four wires
Smart Features And Savings: Includes a free mobile app for remote control and scheduling. The features list highlights potential energy savings with scheduling (advertised up to ~26% in their material) and remote temperature control to match routines.
Best For: Homes with compatible high-voltage wall heaters and multi-conductor wiring where users want a thermostat-style wall controller rather than replacing the heater unit itself.
Dreo Smart Wall Heater IP24 Electric PTC Space Heater

Integrated Heater With Smart Controls: This DREO product is a wall-mounted electric heater sold as a complete unit, not just a thermostat. It uses a PTC heating element and optimized airflow for rapid room heating.
Performance And Features: Product features include 30° manual oscillation to direct heat, strong airflow at 11.5 ft/s, and a low operating noise (~28 dB). The heater offers an adjustable thermostat, ECO mode and app‑based temperature calibration for accurate readings.
Smart Control: Control options include the included remote control, the DREO app, and Alexa voice commands. The listing notes settings for display lighting and scheduling for convenience.
Application: Suited for installations where replacing the wall heater with a smart-integrated heater is acceptable. It combines heating hardware with smart control in one package, reducing wiring complexity compared to retrofitting high-voltage thermostats.
Dreo Smart Wall Heater WH719S Electric Space Heater 1500W
Wide Coverage And Accuracy: The WH719S model highlights 120° vertical oscillation and precise temperature control with 1°F accuracy across a 41–95°F range. It uses a PTC ceramic element for quick, steady heating.
Smart Ecosystem: The unit supports scheduling via the DREO app, remote access, and voice control with Alexa and Google Home. The listing promotes the ability to match heating hours to routines and control from anywhere.
Design And Use: As an integrated wall heater, it delivers consistent room heat and reduces the need to install a separate thermostat on a high-voltage circuit. The product is presented as easy-mount for indoor environments like bedrooms and offices.
When To Choose: Choose this when you prefer a plug-and-play or mounted heater with smart controls rather than modifying existing high-voltage wiring to add a thermostat device.
Emerson Sensi Touch Wi‑Fi Smart Thermostat With Touchscreen
Low‑Voltage, Central HVAC Focus: The Emerson Sensi Touch is designed for typical low-voltage HVAC systems and requires a C-wire. It is not designed for high-voltage electric baseboard or wall heater circuits.
Smart Features: Offers a color touchscreen, Energy Star features, flexible scheduling, and compatibility with Alexa. The product emphasizes energy savings through scheduling and usage reports.
Why It Appears In This List: Included as a comparison to highlight how low‑voltage smart thermostats differ from high‑voltage solutions. For wall heaters that are high-voltage, thermostats like Sensi are generally incompatible unless the heater has an appropriate low-voltage control interface.
Installation Consideration: If you have central forced-air HVAC or a low-voltage thermostat wiring system, Sensi is a strong option. For direct wall-heater control, consult wiring and voltage specs first.
Buying Guide: How To Choose A Smart Thermostat Or Smart Wall Heater For A Wall Heater
Confirm Heater Voltage And Control Type
High-Voltage Vs Low-Voltage: Wall-mounted electric baseboards and many in-wall heaters operate on high voltage (120–240V). Smart thermostats sold for central HVAC (like many low-voltage models) are incompatible with those heaters. Always confirm whether your heater is high-voltage and select a product designed for that voltage.
Check Wiring In The Wall Box
Wire Count Matters: Some high-voltage smart thermostats (meross, Mysa) explicitly require four or more wires including a neutral or second live conductor. Two-wire installations are common on older heaters and may prevent using certain smart thermostats without rewiring or an adapter.
Decide Between Replacing The Heater Or Adding A Thermostat
Integrated Smart Heater: Buying a smart wall heater (Dreo models) replaces the heater unit and provides built-in smart controls and app connectivity. This can be simpler where rewiring is undesirable.
High‑Voltage Smart Thermostat: Installing a thermostat designed for high-voltage lets you keep the existing heater and gain smart scheduling and voice control. This option requires verifying load capacity and wiring.
Match Power Ratings To Heater Load
Amps And Watts: Check the thermostat’s maximum current rating (for example meross lists 16A) and calculate heater load (Volts x Amps = Watts). Ensure the thermostat rating equals or exceeds the heater’s draw to prevent overload.
Smart Home Compatibility And Controls
Voice And App Ecosystems: Identify if you need HomeKit, Alexa, Google Home or proprietary app control. Some devices support multiple ecosystems (meross, Mysa, Dreo). Also check whether the app offers scheduling, remote access, and energy reports.
Installation Skill And Safety
DIY Vs Professional Installation: If comfortable with electrical work, some high-voltage thermostats are marketed for DIY installation. Otherwise, hire a qualified electrician. High-voltage wiring mistakes can be hazardous and code-sensitive.
Energy Savings And Features
Scheduling And Thermostat Logic: Look for features such as programmable schedules, geo‑fencing, ECO modes, and temperature calibration. These can influence long-term energy use. Manufacturers sometimes publish estimated savings percentages; use these as a guide, not a guarantee.
Temperature Sensing And Placement
Accurate Readings: Thermostat placement relative to the heater matters. A sensor placed too close to the heater can cause cycling. Consider whether the unit offers calibration or external sensors for better room-level accuracy.
Noise, Airflow And Heating Coverage (For Wall Heaters)
Comfort Characteristics: For integrated wall heaters, review airflow rates, noise levels, and oscillation features. These affect how evenly and quietly a room is heated. DREO products highlight oscillation angles and low dB operation.
Warranty, Privacy And Data Practices
Manufacturer Policies: Check warranty lengths, return policies, and privacy statements. Some brands explicitly state privacy protections, and some apps collect usage data for features like energy reports.
Compatibility Checklist
- Is the heater high-voltage (120–240V) or low-voltage?
- How many wires are in the existing wall box?
- What is the heater’s wattage/amp draw compared to thermostat rating?
- Do you prefer an integrated smart heater or a separate thermostat?
- Which smart home ecosystem do you use (HomeKit, Alexa, Google)?
- Will you DIY or hire an electrician?
Using the checklist above and reviewing product specs for voltage, wiring, and smart integrations will help identify the correct smart thermostat or smart wall heater for a specific wall-mounted electric heater application.
