Didn't read that 2g was getting discontinued.

Would have been nice if there was a disclaimer on the website, but the onus is on me.

Too many revisions, documentation could be better

This device has so many revisions that it’s hard to guess what hardware does the specific have. Documentation could be better too, especially for less experienced tinkerers with stuff like ESPHome examples
