People I live with turn lights off? That’s not going to happen.
The HA is Controlled by a Raspberry Pi. It consumes 0.25w so costs around 76p a year to run.

To control the lights in the house, the system uses the same wireless sensors that my intruder alarm uses to sense room occupation. I can set each room to turn stuff off if no movement dected for X amount of time. Each sensor takes 2 x AA rechargeable batteries. When they run out they are charged using a charger connected to a smart switch which the HA system only turns on when my solar panels are generating more than the house is using and our electricity is free.

It’s cost me more to reply to your message than to power my sensors
I better get installing.
