Minimum hardware requirements for HA

Hello
What are the minimum hardware requirements to run HA with zigbee and zwave ? (I mean the soc, RAM …)
thanks

Everything equally powered or higher powered than a Pi3 will do for these basic requirements.

As soon as you have multiple camera streams, AI stuff or other power expensive tasks you need more.

I would like to recomment

  • Raspberry Pi 4 with 4 GB RAM or more
  • Conbee II Stick für Zigbee
  • And in the long run a small SSD Drive (128 GB) instead a SSD card with a good USB3 - SATA Adapter

The drive is for much better reliability compared to a card. Not because of storage memory.

USB Extension cable for the Conbee II to move it away from USB3 components.

Although I didn’t run zigbee or zwave, I happily ran HA Core (Python virtualenv) on a Banana Pi M1 with HDD for over a year before moving to my current NAS solution — and I also ran Plex, Pi-Hole and a home-grown CCTV 24/7 recording system on it at the same time. That’s probably comparable to a RPi 2B in terms of power, although it has gigabit Ethernet and SATA not running on the USB bus, which helps.

That is actually close to my setup:

  • RPI4B 4GB
  • Raspee II add-on module (instead of Conbee II USB Stick)
  • “Endurance” SD Card

I run Raspbian OS, HA Container, Mosquitto, Zigbee2MQTT and Watchtower orchestrated by Docker Compose.
