I’ve recently bought a De’Longhi PAC EL112 air conditioner which I wanted to include into my smart home system, e.g. by automatically activating it once the temperature rises and deactivating it if there’s no need for cooling.
The manufacturer warns to pull the plug instead of shutting the device down via the respective button / remote control since some kind of cleanup operations have to be performed. Yes, the device comes with a remote control, but it is Bluetooth powered, see https://www.delonghi.com/Global/countries/at/BDAs/Bedienungsanleitung%20De’Longhi%20PAC%20EL112.pdf where it say “Die CST-Fernbedienung basiert auf der Bluetooth® Low Energy Kommunikation mit dem Pinguino-Gerät”.
I found some hints on a MQTT bridge for De’Longhi, but not for Bluetooth. Do you have any suggestions on how to integrate it?
