Hello all!
I just finished my first working version of an integration for 433 MHz based sensors. I am using one by Acurite, which provides temperature and humidity readings, broadcast over 433 MHz. These signals can be received by a USB SDR (software defined radio), and parsed via the excellent rtl_433 project.
I’ve assembled this as a Docker container. Right now it is just built for AMD64, as I’m running Home Assistant on an Intel NUC. You can find the project on my Github: https://github.com/jochocki/rtl2hass
This will add any sensors that are received to Home Assistant, via the MQTT Discovery integration. I also added support for devices, so they will show up in the integration panel and can be easily renamed as needed.
This project is open to other contributors, as I would love to setup multi-arch image builds for Docker, as well as a HassIO Add-on, but just lack the necessary skills and knowledge.
Please try it out if you can, and enjoy! This has been a fun project to work on.
