My DIY air quality monitor system has been out of commission for a while and I couldn’t be bothered to investigate it

But

I did this weekend, though, and I think I fixed a few issues too

The raspberry pi zero in charge of storing the readings was struggling, apparently kernel panic

So I reinstalled the flash entirely from a recent image, added my tools and my app, all of which took an hour

Everything is back and I iterated a few times on the microcontroller app, and it hasn’t been smooth but it’s been better than last year

Issues as far as I could see were:

• too many WiFi thingies close together in a small room => RF interference
• the bridge node was spending too much time not reaching storage over HTTP => not getting mesh sync => nodes disconnected

So I spaced them out and I added a timed reset

Let’s see how long this lasts!
