This morning for no reason all the lights in my house turned off, then on again. Looking through the log book there is no record of an automation triggering and Alexa hasn’t recorded a request.
All the entities report being turned off and on by the homeassistant.turn_off/on service. Looking at the log there is a single error which references home assistant being unable to locate a particular entity to action and turn on which I removed at least 18 months ago. I have searched all the yaml code and can’t find reference to the light. Have looked in config, groups, automations.
Initially I wondered about a rogue MQTT message, but some of the lights are not MQTT based.
Has anyone experienced similar and have any suggestions?
