I was able to get the original firmware and get the info below:




After that, flashing the ESPhome kickstart firmware was easy.

The relay and the LED work fine, no problem at all, but I was not able to make the sensor pin work.
I try to mark the pin as an input_pullup and other pins as well, but nothing works.
I have two of it and the result is the same for both.
Can someone help me figure this out?

This is the code that I use:

Do you have original 2 MB flash backup so we can double check?

So basically, extraction tool determined that P26 is input/button, but yet it's not working at all? Have you tried all pull up/down/etc combinations?

And you are saying that both pieces are not working.... maybe a software error?

Have you tried to configure it, for now, as a simple switch, without delayed_on_off?

Curious how it would work with OpenBeken?

Hi p.kaczmarek2
I uploaded the original flash so you can take a look too.
I was using the ltchiptool to get the information from the original firmware, now I try to use the BK7231GUIFlashTool and get new info.

Device configuration, as extracted from Tuya:
- Button (channel 1) on P26
- WiFi LED on P9
- Door Sensor (channel 1) on P8
- Relay (channel 1) on P6

The pin 26 is the Button behind the the device, the door sensor is in the Pin 8.
I flash it again with the kickstart to test it, but still not working.



I am going to try with the OpenBeken to see if it works with it.

I'm so stupid, the magnetic sensor is in the S3+S4 contacts, not in the S1+S2, this are the relay contacts
Any way, this are the correct pins!

Device configuration, as extracted from Tuya:
- Button (channel 1) on P26
- WiFi LED on P9
- Door Sensor (channel 1) on P8
- Relay (channel 1) on P6
