The same problems here. The temperature is "frozen/stuck" on a not actual value. I can't change status. There is no history available.

After Ewelink last update (3.5.6 , december 5) all devices do not show the actual status the Sonoff TH device have a block temperature and no detection (Example: at home there are 16 degrees and they are stop at the last detection at 20 degrees - the lights with the timer turn on and off but remains on the Ewelink app with the last state recording). All device have last update on board (2.6 or 2.7).
