Two of my v2 hub updated to 61.6 earlier today and now I have about 10 zigbee devices offline. They are mostly Tuya battery powered sensors (temperature/humidity, leak, contacts and motion) using @Mariano_Colmenarejo’s drivers. Rebooting the hubs has not helped. Some of the devices have come back online only to go offline again.
Three of them are temperature and humidity sensors with child thermostats used for heating, so I can’t switch to a different driver without loosing the thermostat capabilities. Fortunately it summer and there is time to find a solution.
I thought v61.6 was supposed to minimize Zigbee offline problems, not create them.
