I have a “semi-smart” Arete Meaco 12l Dehumidifier. Its Android App can be used in my Guest WiFi. Nevertheless it seems one can implement it via Tuya into HA. I will try this out now.
Regarding your post: At least me I didn’t really understand ow you use your HA. Just to controll that dehumidifier? And 0,4-12V seems way too few for a 230V machine?!
