I was able to install Home Assistant Core on Raspberry Pi Zero W, but I could not get the add-on for the Zigbee dongle to install, and the additional cabling and adapters to cope with the Zero W looked ugly.
Home Assistant recommends either a Raspberry Pi 3 or 4 - installation is easier than with something else. The full-sized USB ports made set up easy without attaching a keyboard and monitor. No heat sink on it, and still the case over the CPU is cool to the touch. I didn’t need something more expensive that would run hotter. You can run it on a Raspberry Pi, but it is tricky enough to get going that I wrote this step by step guide.Ī 3D printed case, a Raspberry Pi 3B+, a Sonoff Zigbee 3 dongle, and a 5v power wall wart.
Home Assistant is a flexible, open source, home automation server. This pictured compact unit is the entire hardware.
