Unbelievable!! Plugged in to my new MiniSplit System Breese33 and worked great for Home Assistant. Not all features worked such as LED off/on but who cares. I can turn the unit off and on, set the temperature (it also reports current temperature of the room), select fan speed and even the sweep function. It's a win win for me. Thanks for saving me big $$. Setup was easy. 1. plug in module. 2. Using my phone select AC-wifi network and enter password slwf01pro. then select your network and password. In Home Assistant under Devices you should find your new device... finish by adding to your dashboard.
