I have several smartplugs that is wifi conneted.
[deltaco smartplug]
They are connected to some heaters in my summerhouse.
I first used the tuya smart app, but them connected them to my Homey.
They worked fine for about 2 month.
I went to my summerhouse the other week and put on the heaters. Or so I thought.
None of the plugs was on. They was online all of the time.
I tried several times to switch them on and off. The app said that the plug responded but nothing happened.
As a last resort I went into the tuya app and sure enough, they worked fine from there.
I still could not get the plugs to respond from Homey app.
