Manually upgrade the pyopenssl library in your venv.

(homeassistant) homeassistant@MYHOSTNAME:~$ pip3 install --upgrade pyOpenSSL

I spent in google search results to find a lot of information for my first production HA installation.I’m having some issues trying to install HomeAssistant Core onto a Raspberry Pi 3B+.

1.Install HomeAssistant Core without venv.

2.Install HomeAssistant Core with venv.

3.Install Home Assistant Core using the docker containers

Getting HA running in Docker is as complicated as:

  1. Install Docker + Compose
  2. Create the compose file
  3. Run docker compose pull && docker compose up
4

RPi 3 B+ - 32bit or 64bit?

Raspberry Pi OS

Raspberry Pi OS (32-bit) Compatible with all Raspberry Pi models
source:Raspberry Pi OS System: 32-bit

Raspberry Pi OS (64-bit)

Compatible with:

Does HA run faster on the Raspberry Pi 3B+ if i install the 64 Bit version? Are there any benefits compared to 32 Bit version?

I had problem with my rPi 3+ and the 64bit version, and I installed the 32bit again.
I think there was not enough RAM memory and the rPi was freezing.

64-bit OS takes more RAM by default

If you have a more memory-starved Raspberry Pi, like the Raspberry Pi Zero 2 W (512MB of RAM) or the 1GB Raspberry Pi 3 or 4, you might be better off using the 32-bit OS.
source:Raspberry Pi OS 64-Bit Vs 32-Bit

I tried both versions (32 and 64 bits) of Hassos in my rpi 3b+.
Unfortunately I2C does not work.
I’m having issues also with onvif camera; ffmpeg seems missing.
