Hi everyone. I’m looking for a device to install Home Assistant on to manage a smart thermostat, a programmable light bulb (on and off), and another lamp in my house. Since I’ll be doing other work in the future, I want to use Home Assistant to be ready for the future.
That said, I’m looking for a device (a Mini PC, a Pi, etc.) that consumes very little power, as I’ll be using it exclusively for this purpose. Do you have any suggestions? Thank you in advance!


My pi3+ has been running for 8+ years on the same card. I ran out of processing and ram before the sd gave out. I only buy top-notch a2 cards.
I just upgraded to a pi5. To handle all of the integrations and devices I’ve added over the years. Still plan to stay on the sd until the price of other options comes down again.
Would be a good idea to check how close you are to the write limit, then. Pricier cards have a higher write limit, but all SD cards are limited.
Luckily, once you hit the limit, it turns read-only, so you can move to a new card pretty easy, but it will happen eventually.
Neat to know you’ve got a longer life out of the card you bought, though! I’ll have to look into cards that have a higher write limit for my next Pi project!
