Midea AC
The default Midea integration does not support most common Midea devices. To support common Midea M-Smart devices like Air conditioners, Fans, Water heaters, Washers, etc you will need to install a HACS addon (See Enable HACS if you don't have/know about that first).
Unfortunately the main "Midea AC Lan" add-on is broken and appears abandoned by the initial developer (a common problems with HACS addons). However there are a few forks which have continued development and fixed issues. The most well supported fork I have found is: https://github.com/wuwentao/midea_ac_lan
To install
Note: If install fails, make sure you did not select the other "Midea AC Lan" in HACS. It has more downloads listed, but is also broken.
