Aqara Smart Radiator Thermostat E1 (Zigbee)

The Aqara Smart Radiator Thermostat E1 replaces your traditional radiator thermostat head with a sleek, connected device that gives you precise control over room temperature — all without wiring. With Zigbee 3.0 connectivity, smart scheduling, geofencing, and window-open detection, it’s ideal for anyone looking to boost comfort while saving energy.

Key Features

• Zigbee 3.0 Connectivity
  Works with your Zigbee hub or gateway for local control; future Matter support via OTA updates.

• Smart Schedules & Grouping
  Create daily or weekly heating programs. If multiple radiators in one room are installed, they can act as a group for synchronized control.

• Geofencing & Multi-Home Support
  The thermostat can trigger heating when you approach home (or in multiple household setups, different automations per address).

• Window / Door Open Detection
  Automatically cuts heating when a sudden temperature drop is detected—or via pairing with a door/window sensor—for better energy efficiency.

• External Sensor Support
  In linked setups, it can take temperature data from another Aqara sensor (e.g. temperature/humidity sensor) for more accurate room control.

• Frost Protection
  Prevents pipes from freezing by maintaining a minimal temperature level when ambient drops too low.

• Colorful Backlit Display
  Easy to read icons and temperature values even in darker rooms.

• Easy Installation & Compatibility
  Fits standard radiator valves (M30 × 1.5 mm) with included adapter sets (RA, RAV, RAVL). No special tools needed.
