I found this for tasmota:

https://github.com/arendst/Sonoff-Tasmota/issues/2839

but I couldn't quite follow exactly what they did. I have done a dozen sonoff wifi switches and they work fantastic. I bought this hoping I could get it to work with espeasy. If not I would use it as is.

Does EspEasy support this device? I purchased one and it seems to have the same pin's to flash. I didn't see anything on the wiki or a search here.
