Sub-$100 Networked 433Mhz Receiver for Home Assistant

I previously wrote about my install of RTL-433 on a Raspberry Pi, running Raspberry Pi OS Buster. With the release of Bullseye, rtl-433 is now merged into the repository and doesn’t need to be compiled from source. So, I thought it would be a good time to revisit this project and make a video about it, this time using a cheap eBay thin client instead of a raspberry pi, and showcasing my setup a bit.

Not Every Project Works, And That’s Okay

In my previous tests using Software Defined Radio (SDR), I used rtl_433 to successfully receive data from an outdoor weather station sensor. Always seeking more data, I found rtlamr - a tool which decodes smart meter data. I don’t really need to read smart meter data since the only smart meter I have is my power meter and I already have my own meter for that, but I still was excited to give it a try and see what I could find!

Low-Cost 433Mhz Sensor Network with rtl_433 on Raspberry Pi

I’m fairly protocol agnostic in my home automation system, and that’s one of the benefits of building something with open source software like Home Assistant - there’s no vendor lock in and you can pretty much connect anything you can pull data from into it. While I’ve set up a Zigbee network for my blinds and ordered a ton of cheap sensors from Aliexpress to test, and set up a reliable Z-Wave network with more expensive sensors and lighting dimmers, I’m always looking to expand the wealth of data I can capture.
