Sudden problem with (2) Aeon Minimotes since yesterday

Aeotec Minimotes stopped working

Somewhere around the 1st of the month the Aeotec mini motes V1 stopped working. I have 3 active units and they all stopped. Last night I tried to exclude and rediscover one of the devices I was able to exclude the device but Smartthings will not discover this as a device any more. It seems to rejoin to the hub but is no discovered as a device. Anyone else seeing the same issue. Smartthings stability has fallen off a cliff in the past two weeks.
