Well, this is some welcome news!
Well, something is turning them on...
- Do you have your Hubitat hub integrated with any other external system other than Amazon Alexa? (e.g. Google Home, Apple Home, etc...)
- What type of lights are these? Are they directly paired to the Hubitat hub via Zigbee or Z-Wave? Or are these lights connected to a Philips Hue Bridge and then integrated with Hubitat? Or are these WiFi lights (e.g. LIFX) or some other cloud-connected WiFi lights? The command to turn on these lights might be coming from an external system.
