We bought 5 of these for our office to turn aircons off when loadshedding hits. Works great, except that they constantly keep losing wifi connectivity. They do reconnect eventually, but this means that some of them often don't get the HA command to turn off or on because it happened to be disconnected at the time. They are within a few meters of the AP. Anyone had any issues like this with these units? We mounted them next to the main DB in their own enclosure so I didn't think all the current in the DB should have any effect on the Wifi signal?!
