I got another 4 of these flashed without much drama. Much easier and faster after you’ve done your first.
There’s an opportunity to use these things as ble scanners (or bluetooth proxies?).
But I know those things are memory intensive, so maybe not a good idea.
I had a go at using a common config using include.
In the devices yaml (arlec-smartplug-3.yaml)
