Hi,
HA suddenly stopped working for me. The UI still loads but all switches are disabled – TPLink and LIFX. All of a sudden. No changes made to configuration in weeks.
The LIFX and TPLink phone apps still continue to function just fine in controlling the bulbs and switches, so the devices are all definitely online.
My HA logs contain:
