Shelly 1PM switches off for no reason

    I have a Shelly 1PM that switches off for no apparent reason just after midnight each day. I have never had it on a schedule or in a scene and I have checked all the settings I think are relevant.

    Code
    {"name":null,"appliance_type":"General","ison":true,"has_timer":false,"default_state":"on","btn_type":"edge","btn_reverse":0,"auto_on":0.00,"auto_off":0.00,"schedule":false,"schedule_rules":[],"max_power":0}

    What am I missing? Is there a more detailed event log so I can see what the trigger is?

    Next step will be a factory reset.

    Thanks!
