Home assistant set up on a raspberry pi 2b in my van, as it only requires 5v/1.2A so I can power it from a normal USB port.
Set it up with tailscale and I’m using the custom integration Remote Assistant which allows me pull all the entities into my home instance. It works great, the weak link tends to be my 4g router!
Not using it for too much yet, hoping to hook it up with my solar charge controller and get some WLED lights set up.
(it’s not normally plugged into the TV, just checking it had started correctly)
