MQTT Ingest Module for Weewx

I've written some things about home monitoring/automation before (see: https://blog.kroy.io/2017/12/19/monitoring-home-power-consum...)

After Acurite shennanigans finally broke my setup, I wrote an MQTT ingest module for weewx, because I couldn't find one that worked.

With some fairly boilerplate ESP32 code, it's trivial to hook up whatever sensor you want.

I tried to keep it generic as possible. Cheers.
