A block heater that has the car warm right when you leave
A Home Assistant blueprint that starts a car block heater from your departure time and the outdoor temperature, and switches it off after you leave.
How the projects are made
- Tested day to day
- Everything here is in daily use. When a winter morning shows a flaw, the fix lands on the page too.
- Ready to copy
- Packages, blueprints and dashboard YAML with neutral entity names. Swap in your own sensors and it runs.
- Built-in first
- Home Assistant’s own cards and helpers wherever they do the job, so updates don’t break your setup.
