Update: This issue has been fixed through a cloud update.

@Darek1988 Done.

@UKLz One temperature sensor can be linked with multiple KE100. But one KE100 can only choose one device as its external sensor.

@Ariadne2 Is your KE100 linked with a KE110? Please share more details here. For example, did you receive any error when enabling the Boost function? How did you try to override the smart control?

Hello everyone, regarding the issue discussed in this thread, our R&D team has provided a beta firmware as a temporary solution. The official release is on the way, i'll keep you posted if there is...

@UlliE Did you change the target temperature on any KE100? This message will occur if you do that.
