I'm working on a similar nodemcu based system that was originally proposed by Bruh Automation https://www.youtube.com/watch?v=jpjfVc-9IrQ later updated by digiblurDIY https://www.youtube.com/watch?v=9Yu57vjz7AY to use ESPhome https://esphome.io/ with no progamming. This looks interesting, but somehow it always seems wasteful to use full blown Linux servers for this stuff, so I'm dabbling in something smaller. :)

Weirdly coincidental timing on this! I've been working on a PCB design (FeatherWing form factor) to track weather data on my hikes, making use of a BME280 and a GPS module. First revision of the board[1], I discovered that the sensors started out accurate, then drifted up to a steady 3° above ambient. Probably because the GPS module was heating up. So last night I found myself reading up on design considerations for…

Hi Joey - yes, this is one of our boards. :-) Are you sure it's the GPS module - 3 degrees sounds a lot for that? I'd try to take some measurements to confirm it before changing anything. Which Feather board are you using?

This is amazing. I'm going to add this to a fun weekend project to monitor air quality in my neighborhood.
