Rack mount raspberry pi for home assistant
Raspberry pis are useful for a lot of tasks. Here I am using one as a home assistant satellite device.
What does it do?
I have a dedicated server that runs many services, including home assistant. This raspberry pi has 2 functions it performs in tandem with this server.
- Wyoming Satellite
A wyoming satellite is a rpi that acts as a voice assistant, much like an Amazon Echo or Google Home.
- Zigbee2MQTT broker
A z2m broker is basically a zigbee hub. So instead of getting a proprietary hub like a hue bridge, you can use a raspberry pi. This can be done directly on the home assistant server, but I wanted to separate it so I could control my lights even if the main server was offline for whatever reason.

Don't plug the dongle directly into the pi. Use the USB extender.

Glue them together, paint it, assemble the electronics, mount on your rack.
