Aqara E1 TRVs and their temperature readings

Configuration Zigbee

I have a few Aqara TRVs hooked up to HA with ZHA.

One slightly strange thing I have observed is that the temperatures for each is presented as a decimal, however the bit after the decimal never changes, and each device has a different value.

For example, one will only ever read .8 (e.g. 16.8, 17.8, 18.8°C and so on), another will read .3 (e.g. 16.3, 17.3 and so on) and another .2 (e.g. 16.2, 17.2…)

Anyone have any idea what’s going on and why that’s the case? Is it a quirk with the quirk, or a quirk with the device? Can I increase the resolution of the temperature they report?

Same issue here. I believe it has to do with the frequency/sensitivity when the TRV sends the data - it seems to me that AQARA TRV sends the change in temperated when the delta is 1 Celsius. Thats why reading is 16.2, 17.2 etc… Would anyone know how to change the setting so that it sends the data at smalled change, for example 0,1 Celsius?
