I’m using the 4 channel MHCOZY Zigbee Relay in my chicken coop outside (50 yards from the house but has lots of mesh connections to outdoor lights, etc…)
I had no problems pairing and it worked flawlessly at first… but within a few days it began intermittently failing to execute when I try to activate the relays. But it still shows the device as available. I also have a battery powered door sensor and temp sensor within a few feet of it and they have had no issues. So I’m not sure if it’s a radio/interference/connectivity issue or something else, but like I said it appears to be connected and available without interruption, it just isn’t turning relays off and on.
Also of note… when I turn the relays on via the buttons on the board itself, it reports that state change immediately, if I then tried to turn off the same relay via HA it seems to stall.
See attached screenshot for the error I get when I try to reconfigure.
