Best for: Higher-load baseboards with a four-wire installation. This model extends remote control via the free app and supports temperature and humidity alerts. It is well-suited for users who want precise control, including remote monitoring. Limitation: Requires four wires with a neutral or second live wire, and compatibility with older two-wire systems should be checked before purchase.
meross Smart Thermostat for Electric Baseboard and In-Wall Heaters
Best for: Those needing four-wire installation with broad voice-control options. The device supports high-voltage systems and offers compatibility with HomeKit, Alexa, Google, and SmartThings. It emphasizes a straightforward install time and clear load ratings for 120V-240V. Limitation: The setup note indicates a need for multiple wires, which may complicate retrofits in older homes.

Caution: It is a more classic solution and lacks the full smart-home features of WiFi-connected thermostats.
Buying Guide: Smart Thermostats For Electric Baseboard Heaters
- System compatibility: Confirm your baseboard heater is high voltage (120V-240V) and uses four wires (including a neutral or second live). Some models require four wires; others may support older layouts with limitations.
- Connectivity and ecosystems: Decide which platforms you need (HomeKit, Alexa, Google, SmartThings, or Matter). Some models offer direct WiFi without a hub, while others promote broader ecosystem compatibility.
- Scheduling and energy savings: Look for 7-day or 5-2 day programming. In-app schedules that adjust when you’re away or asleep can reduce energy use without sacrificing comfort.
- Installation complexity: Check the wiring requirements. If you’re replacing an older thermostat, ensure the existing wiring matches the device’s needs. Some models advertise quick installs, while others require professional wiring.
- Display and alerts: Consider adaptive brightness, humidity/temperature alerts, and user interface. A clear display helps for quick adjustments, while alerts help you monitor comfort and efficiency.
- Reliability and updates: Firmware updates can improve performance and security. Favor models with ongoing software support and documented compatibility.
