Same problem here, did you find a solution? Any pointers from the dev team on where to look and try to fix this?

I managed to fix this bug without any knowledge of the internal workings of this plugin but maybe the developers can fix it easily from here. It seems that the additional subtraction and division that is going on here is not necessary: https://github.com/georgezhao2010/midea_ac_lan/blob/master/custom_components/midea_ac_lan/midea/devices/cd/message.py#L69

By setting the values likes so the properties actually seem to be correct:

self.target_temperature = body[3]
self.current_temperature = body[4]
self.max_temperature = body[10]
self.min_temperature = body[11]
