2 almost identical VeraPlus. Only difference - one with EU ZWave frequency, one with RU.
2 idendical Xiaomi Aqara door sensors. (lumi.sensor_magnet.aq2)
Door sensor installed, one - works for half year with no problem
Second - stop responding after 3-4 hours.
Paired with second VeraPlus - works well about 3 month
Paired with first VeraPlus - 3-4 hour and “Can’t detect device”, CommFailure variable set to “1”
Situation repeated one to one.
Ok, test Zigbee module of first VeraPlus:
Pair Aqara Smart Plug with first VeraPlus. It… It works wery well for a long time.
Pair with second VeraPlus - works wery well for a long time.
Possible reason is:
Door sensor - battery-powered. Not pollable
Outlet - AC powered, polling allowed.
But no settings to check or correct.
