Thank you, I will just note here that this:
Code: text Expand Select all Copy to clipboard
Flag 10 - [MQTT] Broadcast self state on MQTT connect

will be set by default in future releases.
Also, if you are using this:
Code: text Expand Select all Copy to clipboard
Flag 21 - [MQTT] Retain power channels (Relay channels, etc)

then you don't need to set:
Code: text Expand Select all Copy to clipboard
Flag 7 - [MQTT] [Debug] Always set Retain flag to all published values

it does the same as your device has only power channel (no BL0937 etc etc)

Obserwują temat od kilku miesięcy, gratuluję i dziękuję Tobie za świetną robotę!
Mam gniazdo LSC Smart Power Plug w wersji 2.0 (Art. No. 970762 v2.0) kupiony kilka lat temu w polskim sklepie Action.

Zastosowałem następującą konfigurację:
P7 (PWM1) - LED 0
P24 (PWM4) - Rel 0
P26 (PWM5) - Btn 0

Działa bardzo dobrze z MQTT i homeassistantem!

Hey @robkry , we don't have 970762 device on our database yet. Would you be able to provide a device photo or a photo of a packaging? Thanks!

Dodaję zdjęcia wersji 970762:

Gdyby pojawiały się błędy przy odczycie bądź programowaniu pamięci, proponuję wylutowanie modułu WB2S (tak było w moim przypadku).

Thanks!

And here's a repost of my short description how to do desoldering/soldering WB2S:
p.kaczmarek2 wrote:

Just desolder CB2S.
First add some flux to the pads and remove solder with soldering wick:

Then solder the wires:

Then power module from 3.3V and connect to USB to TTL:

Then use BK GUI flasher. If it doesn't work for you (there are some rare reports that BK GUI doesn't work with certain USB converters, but hid_download_py does), use hid_download_py method from this video:

Make sure that OBK access point shows up.
Then desolder wires, and clear the module pads:

Then prepare to solder back the module, add some flux to the pads:

And solder back the module:

I hope that somebody will find that useful. Have fun soldering!
