W100 (Remote Temp Sensor) Association to E1 TRV is Unstable

Hi, what’s the problem, I just checked and everything works. Did you create a group with E1? [Screenshot_2025-11-09-12-22-59-397_com.lumiunited.aqarahome.play] After creating a group, go to the settings of a separate E1 and bind the temperature sensor to the W100. Let me explain: two E1s are bound to one W100. Second step, from W100, bind it as a thermostat to the created group. Everything is similar to what is described for W500.

Hi @timo_degen I had the same problem and after several attempts I found the right settings by following and modifying the @gafich10 guide. it will definitely work for you too.
