A good and cheap TRV for Home Assistant via Matter that runs locally without the cloud. Be prepared for manual firmware updates via the Aqara app, and regulation based on a room sensor in HA. The display might face the wall after installation – in the case of a perpendicular installation.
Works via Matter/Thread directly with Home Assistant, without an Aqara hub and without the cloud
Pairing with HA without any problems
Via Matter it shows the battery (%, voltage) and supports temperature calibration
Good price on sale
Firmware doesn't update via Matter: factory version 1.0.0.6, yet HA reported it as "up to date". Updated to 1.1.1.2 only via the Aqara Home app by switching to Zigbee and back (no hub required), with a reset and re-pairing
Valve position is missing via Matter
It measures the temperature next to the radiator (it was showing 28°C), and without an external sensor or calibration, it regulates based on an inaccurate reading
External sensor, window detection, and schedules are only available in Zigbee mode or in the Aqara app. In HA, this can be managed via Better Thermostat and automations.

It took a while, but after the 0.0.0_2745 update the headers are finally working.

The head overheats by 1-2 degrees, the connection to the external sensor works in the application but does nothing. Unfortunately, the product absolutely did not meet expectations
Slim clean design
Basically, it's not able to maintain the temperature in the room at all

It overheats by 0.5° and then switches on only when the difference is -2°. It should have PID control, or at least PI, but obviously it doesn't work as it should, which is the case with rads. the warhead is a major problem. This has been addressed on the manufacturer's forum and may be resolved in a future FW update.

Lovely design
Quiet
It's not heating at all according to the set plan. Even if it's set to 25 and the room is 20, it sometimes turns on, sometimes not.

very quiet head compared to the previous E1
more settings than the old head, temperature offset, etc.
lifetime 2 years compared to 1 year for the previous one
umi matter, but I use zigbee in aqara vide function
display numbers can be rotated
the display is a bit blurry. the old dsplay was nicer.
quality ok, but could the head look "better"

After switching to Zigbee, Zigbee2MQQT can be added to Home Assistant (ZHA does not yet support the device)
Easy installation on the radiator + lots of adapters in the package
The head is extremely quiet. The radiator itself makes more noise
To switch to Zigbee, you need the Aqara app
