I received my AirGradient One Version 9 kit last week and flashed version 3.0.6 across to it via my Windows 10 laptop (getting the BOOT error during flashing, but using the instructions on the webpage). I then connected it to my WiFi, while still connected to the laptop, and it started sending readings to the dashboard.
However, when I disconnected it from the laptop and plugged it in to a normal power socket, it refused to connect to WiFi, and I haven’t been able to fix this. I have now flashed version 3.0.8, but this hasn’t helped. (It wouldn’t flash if I selected ‘Erase the Device’, if that’s relevant/helpful.) I’ve tried connecting when it’s plugged into the wall, and also when plugged into my laptop, in different locations in my house, to no avail.
I’m sure it’s something simple, but this kind of slightly technical electronic/IoT/WiFi problem is way outside my areas of expertise, so I’d really appreciate it if someone could hold my hand through this!
