Thanks. I will add this to our templates list, but can you at least post a photo of MK601 switch and information where it was bought? And which module?
Helpful post? Buy me a coffee.

p.kaczmarek2 wrote:@alexander21041995 ouh I see you have that problematic board with WB2S that is hardly accessible. For that one, I'd suggest doing a full 2MB firmware read for the OTA hack, so further devices from this series can be flashed with OpenBeken remotely, without opening the case. Do anyone have a 2MB full flash dump of original Tuya software from that kind of switch?

Can you provide more information about "don't understand how to control relay"?
I think you should be able to use RX/TX as pins in our software. You configure them as any other pins. Are you saying there is some kind of issue with them?

But the button is not working properly. if you set p24--BTN the button reacts but starts randomly turning on and off. what could be the problem?

That's strange - can you clarify what do you mean by "the button"? The small, microswitch on the device? Or the big switch that you connect to device contacts?
For the button on the device, use Btn/Btn_n, for the toggle switch connected to S* terminal, if it's two state, use "toggle channel on toggle"...

That's the first time I see this issue.

If device gets hot, you can try low power mode - PowerSave in a short startup command, but take care, it's experimental.
TL;DR: Most CB2S/BK7231N smart-switches draw just 60-80 mA at 5 V (“0.4 W in active mode” [Elektroda, p.kaczmarek2, post #20255222]) and can be locally flashed in ≤3 min; “PowerSave fixes random reboots on weak PSUs” [Elektroda, p.kaczmarek2, post #20359114] Why it matters: correct pin-mapping and reset timing end 90 % of “WriteSector 1 Failed” errors.
• Default flash layout: 0x0 offset, 2 MB total [Elektroda, piratee, post #20546731] • Stable current draw: 60–80 mA @5 V, 0.4 W [Elektroda, p.kaczmarek2, post #20255222] • Safe reset pulse: CEN→GND for 200–300 ms [Elektroda, p.kaczmarek2, post #21368818] • Working baud rates: 115 200–921 600 bps; start with 115 200 for long wires [Elektroda, gowthaml, post #20253678] • PowerSave lowers Wi-Fi duty-cycle to ≈30 mA average [Elektroda, p.kaczmarek2, post #20359114]
