So yesterday I went to have a nice hot bath only to find there was no hot water Later I checked HA found that āIā had turned off the water heater 4 hours earlier (no I did not!)
The relay is connected via z-wave. Since I wanted only to monitor consumption I had removed the relay switch control from the interface, making it impossible that I could have turned it off. Now my question is, who turned it off in my name?
Is there some security audit trail I can look at?
