I won't discourage anyone that wants to take things into their own hands, but this level of DIY seems too deep for me. I've gotten a great balance of reliability and open data/DIY spirit by using an off-the-shelf consumer weather station and just intercepting its signals with an RTL SDR running RTL_433 and piping the data into a prometheus instance.

Honestly, if you're in town, you're probably within radio range of someone else's station already for free.
