You had successfully set up your Sensibo device and connected it to your wifi network but:
1. Sensibo does not control your Window / Portable AC at all.
2. Sensibo seems to be sending the wrong command to the AC.
First make sure to set the AC unit, by the buttons on the AC unit itself, to the same Mode, Fan speed and Temperature to match your Sensibo app.
Only when the AC and the Sensibo app show the same AC state, then test if Sensibo is able to control your AC correctly.
You had made sure that the Sensibo app and your Window/ Portable AC are set to the same Mode, Fan speed and Temperature?
Your AC is still being set to the wrongs settings when controlled by Sensibo?
Fix it by selecting a different remote control variant from the Sensibo web app at home.sensibo.com
