[BK7231N/CB3S] Triple touch light switch N-TS10-EU-B3 / N-TS10-B3 - OpenBeken, template, GPI

.
Today I am presenting a firmware change and connection to Home Assistant for another product in the Avatto series. This time it will be a triple light switch based on CB3S. The situation here will be similar to the white single model - I will need to detect the GPIO configuration using the tool GPIODoctor .

Purchase N-TS10-EU-B3 .
This triple switch is available to buy for around £75:
.
This is a relatively good price, especially as this is the triple version, i.e. with three touch buttons and three relays inside. In addition, all the time there is talk of buying from a distributor in our country.

Interior N-TS10-EU-B3 .
The product is worth comparing with its brother version, the single, white, Avatto N-TS10-W1 which I have already described.
.
PCB designation:
EU_CBL_CB_SV2
T=1.6MM
20220409
There are some pads visible - maybe for programming?
.
Relay and power supply board - the power supply is based on a DP2525, as in similar products in this series. You can also see a 3.3V LDO regulator and three transistors (designation J3Y, a classic).
.
The relays are three pieces of JY32FN-S-DC5V-A:

Yes, here is already a small flyback power supply. There is no non-isolated step-down converter here as in other products of this type. Overview diagram of the power supply:

PCB designation of the power supply/relays: YD3L_WF_DV5 20220412.

There are four LEDs inside - one per relay and an additional LED from WiFi/steaming status:



Change firmware N-TS10-EU-B3 .

The CB3S/WB3S leads are online, I soldered the leads to GND, 3.3V, RX1 and TX1:

This time my Flasher did not import the Tuya JSON configuration correctly.
Here are the manually specified GPIO roles:

The LEDs are together with the relays on the same pins.

Summary
The firmware change went without any problems. Slightly worse was the configuration. This time it failed to extract the JSON Tuya configuration batch from the 2MB copy so I had to guess it manually using the GPIODoctor tool. Fortunately, this only needs to be done once, and I've already done it for you, so if you want to flash such a product, you can copy the template from me.
On the other hand, what to do next after flashing is already shown to you by, among others, our Youtube channel Elektroda com:
