What the differences mean

Apple Home

The Aqara Radiator Thermostat E1 works with Apple HomeKit through Aqara's hub. The Sonoff Zigbee Thermostatic Radiator Valve reaches HomeKit and Matter only through a SONOFF Hub, so in an Apple home the Aqara is the simpler path.

SmartThings

The Sonoff works with SmartThings directly; the Aqara needs an Aqara hub for it.

Batteries

The Aqara runs on 2 AA cells rated for about a year. The Sonoff takes 3 AA cells and its battery life is not documented, though its owners report many months.

Child lock and geofencing

The Sonoff documents a child lock, which the Aqara's listing leaves unspecified. The Aqara documents geofencing to heat the house before you get home, which the Sonoff's listing leaves unspecified.

Which one to buy if

What owners say

Owners of both valves agree on the good part: installation and pairing take minutes, often several radiators in one sitting, and batteries last a long time. Both groups also mention a valve motor that can be heard when it adjusts. Aqara Radiator Thermostat E1 owners single out external temperature sensors for accurate room control, geofencing that warms the house before they arrive and frost protection, but a meaningful share of long-term owners report brittle mounting splines, a motor that pops the housing loose or lost pairing after a year or two. Sonoff Zigbee Thermostatic Radiator Valve owners praise the on-device display for anyone in the house and the child lock, and warn that the motor noise suits bedrooms poorly without the supplied noise-reducing adapter and that a valve occasionally drops off the mesh.

Price history compared
