![]() I’ve done this before on the Arduino platform and it works well. Rather than install and maintain multiple instances or extend HA, it’s probably cheaper, faster, better to craft a quick Python script for the Pi that connects to the MQTT component. I’m running HA on a VM, not a Pi so there’s nowhere to physically plug the Enviro pHAT. I was also wondering where you put the IP address and what code you run on the Pi to get them talking. Where hostname: is the configuration option allowing for multiple device targets, and rpi-zero-one and rpi-zero-two are the hostnames of each of the Pi Zero’s on the network For further details about HASSbian, take a look at the documentation. To try it out, go to or if you’re using Mac. I’d like to be able to do something along the lines of: sensor: Wait about 15-20 minutes and voil you have your Home Assistant on your Raspberry Pi Zero W in 30 minutes. In the above scenario both the Zero’s are using the GPIO on their respective device though there are no options in either of the setups to allow me to select/target the device Pi Zero W - Outside in the garage controlling my garage door via Raspberry Pi Cover.Pi Zero W - Outside on the patio connected to a Enviro pHat.Pi 3 - This Pi would be in my study, indoors and running HASS. ![]() For this project, Im going to use a cheap Raspberry PI Zero W. Here’s what I’m thinking I’d like to do with 3 x Raspberry Pi’s ( 1 x Pi 3 & 2 x Pi Zero W) Install home assistant supervised docker raspberry pi 4. I want to be able to have many Raspberry Pi’s connected to the network with only a single instance of HASS. Theoretically that could be an option, though I’m hoping for a much simpler solution:
