Been meaning to DIY a weather solution too...just need to figure out how to power it on balcony (no power). Thinking perhaps via the new sodium batteries & explore that too while at it.

If you live in a moderately dense area or know a neighbor who also has a weather station, you might try the command line utility rtl_433[0] mentioned in the article with an SDR dongle to pick up existing broadcasts in your area. I pick up three different stations consistently!

I did try it a while back and only picked up industrial fridges...presumably a restaurant...apparently those run on same tech

Moving soon though so should give it another try then
