if this can help someone, could not find this particular model in your database cheap: 3.5$ Amazon a simple relay switch Sonoff form factor NOTE: in the pinout image GPIO 0 = CEN uses BK7231N, and your firmware tool works perfectly on this device. love the HA discovery tool, thanks

Thank you for sharing, but why did you mark GPIO 0 on Beken device? GPIO0 is only for ESP. By the way, I'm sure I saw this device in ESP version in the past. I recognize this board layout. We had user asking about it, here on forums. PS: Remember to enable PowerSave, this device has low quality power supply.

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:
