I've been reflashing and setting it up for a long time now, but I couldn't find the config file in the device.json file, so I decided to post it here.

Thanks for sharing, don't forget to use OpenBeken's PowerSave 1 feature, otherwise you'll be doing this repair soon:

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Is it enough to change the team from "startDriver BL0942" to "PowerSave 1"?

no, you need both:

backlog startDriver BL0942; PowerSave 1
