Mysa Smart Thermostat for Electric Baseboard

Quick verdict

Mysa fills a gap that almost nobody else does: smart control for electric baseboard heaters. If that's your heating system, this is essentially your only good option. It leans on the cloud by default, but because it supports Apple HomeKit you can pair it to Home Assistant locally via HomeKit Controller - a genuine local path - and the clean design makes it the best in its narrow niche.

Standout: Purpose-built for electric baseboard heaters — fills a niche that almost no other smart thermostat addresses.

Compatibility snapshot

Why it stands out

• one of the very few smart thermostats designed specifically for electric baseboard heaters
• good cross-platform support including Apple HomeKit
• clean design that looks much better than traditional baseboard thermostats

Reasons to hesitate

• the Mysa app and remote features lean on the cloud
• for local Home Assistant control you pair via HomeKit Controller rather than a native Mysa integration
• expensive when you need one per baseboard zone

Best for

• homeowners with electric baseboard heaters who want smart control
• Apple HomeKit users with baseboard heating systems

Avoid if

• you have standard forced-air HVAC - this is baseboard-only
• you want a native cloud-free integration (the local path is via HomeKit Controller pairing)

Privacy and local-control notes

The Mysa app and remote features use Mysa's cloud, but the thermostat supports Apple HomeKit, so pairing it to Home Assistant via the HomeKit Controller integration gives fully local LAN control with no Mysa cloud.

Home Assistant support: supported · integration path: HomeKit Controller (local, via Apple Home pairing) or Mysa cloud API.

Buying reality check

Price notes: Premium per-unit price, and baseboard homes typically need multiple units. Budget accordingly.
