I have three Smartenit ZBMLC15 relays which don’t seem to be responding to Hub anymore. I removed and added one of them from Smarthings and re-paired it and it worked for a day or so but has dropped off again. Any suggestions on how to get these devices working again?
Recent zigbee update has introduced a number of weird problems for some people. Definitely contact support.
You can try turning off OTA updates in your account and then doing a forced resynchronization by taking your hub off power (including removing any batteries) and leaving it off power for at least 20 minutes were leaving your other zigbee devices on power. This will do a heal if your zigbee network and may help. Or may not, but it’s worth a try.
I power cycled both the hub and the devices and they appear to be working now.
