👋 What's the process for downgrading the device to an earlier firmware version?
I've got mine upgraded to v3.75 a couple of months ago but it's buggy. It seems that they even have pulled it back as the last available is v3.74

So I'd be interested is there any way to downgrade? 🙇

Hi! I don't know does someone was able to downgrade, but you can try and be the first :) As I know wi-fi modules are communicating with firmware servers by http, not https. You can try to forward wi-fi module to yours rogue webserver with local DNS records, and feed desired firmware file to the module.

That's the idea in my head.
