Could you share the programming for that? Maybe you have it on Github? Right now I have everything running on an RPi because the weather station is remote. But eventually I'd like to have Weewx running in a virtual machine, and the bucket will get connected to a RPi Pico and report the tips via MQTT as you have set up. I'd like to see what you're using to subscribe to the MQTT topic and feed it into the WeeWx loop.
