Yesterday I updated the firmware of my Aqara E1 thermostat using Aqara E1 USB hub.
From 0.0.0937 it was updated first to 0.0.0_825 and then again to 0.0.0_1030
As a result, the battery level updates are not working anymore .. : (
Hopefully, these updates are fixing some other issues that we were not aware of.
Aqara does not follow the Zigbee standards even for the firmware version standard commands, so after the updates this driver (and also HE inbuilt drivers) will still show the old version.. This is next thing to fix in this driver when I have a chance.
I am now 99% certain that Aqara E1 thermostat does not send back to the Zigbee coordinator the actual open/closed status of the valve. Which is very disappointing for me, because most of the other TRVs that I have used so far are sending the valve status (open/closed, or even the percentage!). This was very important for me, because I used it in some nice charts in the previous years, and the percentage of the valve opening is a very good indicator of the effectivity of the TRV built-in PID control algorithm... With Aqara we will have to live without this extra.
