MOES US Matter Smart Plug with power metering. BL0942/ BK7231N FW 1.6.15 boot log 1.7.16 boot log Tuya app offers update from 1.6.15 to 1.7.16 same partition layout as the MOES Matter bulb bootloader has 0 start 00 00 01 00 -> 0x10000 length app partition 00 00 01 00 -> 0x10000 start 00 87 10...

I cannot explain it. Some comparisons for what I think I know so far. Also! I remember now with the MOES Matter bulb that because it uses the standard Tuya keys you can just flash the normal BK7231N bootloader and use standard OBK conversion procedure and general release binary. I'll confirm with this smart plug. That would mean losing the RF calib partition though if it contains anything custom. Potentially it'd be possible to save RF partition, flash standard BL, write back RF, flash OBK. It could be a single-shot Convert MOES Matter Device button in Easy Flasher. maybe

it seems there are a couple of options. -flash a random BK7231N backup in its entirety to this device then use Easy Flasher to convert to OpenBeken as per normal procedure -erase all, flash BK7231N QIO OpenBeken release and overwrite bootloader then write standard non-calibrated RF - all within EF. Either way you seem to end up with a standard OBK device. The template: Code: JSONLog in, to see the code

T8440A is most likely the power supply controller. I guess it's a simple non-isolated step down converter as usual. Probably something similiar to BP2525. It's nice to see a varistor and big yellow filtering capacitor on the board... Can you explain what's going on with these partitions? Why do they have a different layout?

yes, flashing normal Tuya N QIO including BL works fine. transplanting RF from original MOES firmware does not seem to work - mac is not the expected one but rather the default blank/generic

Tuya app offers update from 1.6.15 to 1.7.16

same partition layout as the MOES Matter bulb https://www.elektroda.com/rtvforum/topic4074263.html

bootloader has 0 start
00 00 01 00 -> 0x10000 length

app partition 00 00 01 00 -> 0x10000 start
00 87 10 00 -> 0x108700 length

download partition 00 A0 12 00 -> 0x12A000 start
00 60 0A 00 -> 0xA6000 length

will require build like PR https://github.com/openshwprojects/OpenBK7231T_App/pull/1340 to cater for different RF/TLV at 1E3000

Can you explain what's going on with these partitions? Why do they have a different layout?

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:

Either way you seem to end up with a standard OBK device. The template:
