Nedis WIFIP110FWT (BK7231N, BL0942) teardown
First unscrew and detach the plastic ring
Then desolder the antenna cable
Measure the total length of the outlet pins towards the plastic to have a known measurement when pressing and reassembling. Then remove the circuitboards through pressing the outlet pins
Then you will find the needed solder/programming points
To reassemble, place the circuit boards back in and then place the outlet pins in the vice and leave a small gap so you can fit a wide screwdriver in between to press back the plastic housing back up on the outlet pins. Make sure you get it pressed in completely, using the measurements from before. After this resolder the antenna and screw the plastic lid back on.
Ive found that:
P6 is LED
P9 is Button
P26 is Relay
And for the BL0942 energy metering you would need to use "startDriver BL0942" in startup commands

Thank you for presenting this interesting teardown process. I had a similar plugs once, and it was very problematic to deal with them. Polish teardown NAS-WR01W and NAS-WR07W I had serious issues... [Read more]
I’ve read on this board that its a NAS-WR01W6-T V7 made around 2021 11. So perhaps some copy/resell? [Read more]
They do it all the time. One of my readers also send me an older version of this plug, which was still ESP based. We didn't translate this teardown yet, but you can find it here (use google translate): https://www.elektroda.pl/rtvforum/viewtopic.php?p=20332677#20332677 Have... [Read more]
I can see if I can make one. I have one device untouched. Do you have a link on how to perform it? [Read more]
@clabbe not yet, but I will write an article on that. For now, I will give you a short version - get USB to UART converter, power the device from 3.3V LDO or from 5V if LDO is on board, connect common... [Read more]
