Hi!
What I* have:
- a Raspberry Pi 3B
- a solar PV system with Modbus output
- a heat pump with Modbus output
What I want:
- energy stats of the PV and the heat pump, going back for a few years, without needing cloud access
- trigger the heat pump into overdrive when there’s excess solar
- something that works well on a RPi 3B
- usable phone frontend (not necessarily an app, but kinda like it)
What I tried: Home Assistant – which works but is very complicated and behaves rather funkily on the hardware. I suspect that putting a whole bunch of Docker containers on a lowly RPi is kind of a bad idea. But also, with Home Assistant, there appears to be a rather steep learning curve because there’s just so much stuff.
What I’ve superficially considered but haven’t tried: OpenHAB. Would be interested in learning if that’s better.
(* actually none of these are mine, but for the purposes of this post, let’s assume I have control of all this stuff.)
Strange. I’ve been running haos for some years on a 3b+ which is different but the soc is the same (although slightly higher clock) as is the amount of ram.
As said, I run haos though, not containers. Not sure how you tried it.
Just slap it on a SD card and go… Mostly intuitive.

I don’t know about integrating your pv though. I am lucky with Enphase, although that has some downsides besides generally working.
