This module for my Midea air conditioner works very well with HomeAssistant and solved a problem for me. Serge recommended soldering an additional wire as an antenna which probably would work as well. Communication with the seller is excellent and provided all the info I needed to customize the module. the module arrived with a well-written english instructional sheet that got me online with the module quickly. This module 'fixes' Midea AC Wifi. Its really a must-have for every Midea AC user with HomeAssistant.
