I just do some simple things with my Sensibo units. We live in a hot country (hot all the time) so when we come home the AC gets switched in if the temp indoors is above a threshold and depending on the temperature it gets switched on high or low fan. If high then I use a wait command to send the fan to low once the temp has cooled to a desired amount. When we go to bed I use a long press on a button downstairs to turn all the AC's and lights off etc downstairs and switch the AC on in the bedroom. When we left Ave the house everything gets turned off including rhe AC's. The Sensibo do put a load on the hub because of all the Cloud going on, but they work very well and fast most of the time too. Expensive, but I'm happy with them. I use the original app posted months ago in this thread...
