The last time I added to this series was a few years ago. But a new writer wrote something on WeeWX on the site, and the technology has changed, so I decided to update what I had done. I moved from WeeWX-sdr over to WeeWX-MQTTSubscribe. MQTTSubscribe is actively developed by Rich Bell, and he is very responsive to issues. The extension can act as a driver or a service…so either as your primary source of weather data, or to add additional weather data.

The other advantage is that RTL_433 can run as a standalone service and now supports publishing to MQTT. So, it can decode my weather sensors as well as my 433MHz leak sensors. Oddly enough, I also seem to be picking up someone’s tire pressure sensors as well.

Elsewhere, I assembled custom sensors to get additional readings, running ESPhome, also sending their data via MQTT and being integrated by the same extension to WeeWX. This includes barometric pressure and particulates.

This means my WeeWX installation is much more robust, and modular. This is mirrored in my Home Assistant installation, where I’ve increasingly divided off some subsystems to act more independently.
