EPL full reset/firmware flash

[final rivet]

I got a few EPLs and have been having some issues with their presense. I have been trying to use the ESP Home addon to make sure firmware is update and such, but I think I inadvertently messed one of them up real bad. Not auto-recognized on BLE or wifi any longer, USB hookup to try and connect to ESPHome and not getting anything other than what seems to be generic ESP device.

Is there a documented process for doing a fresh flash of the firmware? Looking at the documentation on everythingsmarthome.github.io doesn't seem to have much in-depth in terms of steps.

Thanks.

Yes there is a factory reset section in the user guide

Scroll down to the manual setup and factory reset section

It sounds like you've overwritten it with a blank firmware, so follow through those steps and you should be good to go
