1 year agoOne can extend battery life with Home Assistant and any phone that can run the HA companion app.
I have a Samsung S9+ stuck on my fridge as a home assistant remote with a script controlling a 5V/1A charger + power switch. It will turn on when the S9+ battery is at 20% and off when at 80%. Charges slow but that is on purpose. HA monitors it’s battery health as well and will notify me when the state changes.
Dietpi is a great suggestion.
Running rpi4 + pihole on dietpi for years now. It is overkill but solid. Updates thru SSH…easy does it.
