Device information
Woox - R6113-4PACK
4 pieces Smart Plug EU, Schucko with energy monitoring
Model: R6113
EAN: 8435606721219
(Bought at Amazon)

Similar to (BK7231N/CB2S - BL0937) WOOX R6128 Smart Plug with Energy Monitoring

Carefully open case (there are clip on the 4 edges). But it's quite easy to open. (see also [BK7231N/CB2S] Teardown CALEX Smart Powerplug EU plus 16A)

For flashing I connected my FT232RL USB to TTL serial adapter as follows with the CB2S BL0937 chip:

The red cable is for reset (=start flashing).
I flashed all 4 devices with the BK7231Flasher.

My config looks like this:

And as I'm mainly using MQTT:

Start-up command:

Web-App config:

You can easily do updates later with the OTA feature in the web app:

Thanks! Please also paste config json from "Launch Web Application" so I don't have to manually type everything into the database.

I only realized it now, but why do you have LED commands for a relay switch (on/off) plug?

I have the same plugs, but I am not able to backup the orginal OEM-Firmware. I just succeded with flash without backup. Can you explain how you did the backup to be able to revert again?

Here is my log:

It always works for me, but we indeed had some similiar issues reported on forum. First I would suggest you to try multiple baud rates (preferrably lower ones), next try to shorten your flashing wires, try other USB to UART converter if it fails, you can also try hid_download_py Python script if new app fails for you, and I also recommend to flash (or read) WB2S (or CB2S) outside the circuit. You can take a look here, this video shows desoldering and soldering method for CB2S:

And this method shows the hid_download_py usage, which is an older, but still good and reliable Python script for BK7231 flashing:

Hey,

thanks for your support. - I bought especially this good part to never have the "try another adapter" problem.
I can report with windows 10 it works like a charm with the same adapter. - So either there is a problem with MONO or DRIVER in Ubuntu. - The strange thing is, pytool for ESP-flash works without any issues. Read and write no issues. With your Gui write works and I flashed without backup yesterday in Ubuntu.

hid_download_py doesn't work for me. There is some error in the skript for Ubuntu 20.04 as I assume.

So maybe we can have a chance to solve the issue.

There were indeed reports saying that Mono is problematic. I am unable to determine what may go wrong there at the moment. Do you have any ideas how to approach it?

It might be easier to fix hid_download_py. What kind of error message are you getting there?
