  • description: 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. As I'm using Home Assistant in my home automation system, anything that can publish to MQTT can be brought in, so buying fairly cheap off the shelf sensors which are rugged enough to survive for years outdoors is a great use case for me, even if there is virtually no security in the 433Mhz world. Overall, I was able to setup the receiver for under $100, which is pretty good as far as home automation products go.
