Informational: S8E Relay GPIO Pins are different #1

First of all, thank you so much for this guide! I was able to use it to configure my S8E.

For others looking to control the relays on their modified Tuya S8E, you need to follow the steps from this guide but I had to substitute GPIO pins 107 (for relay 1) and 108 (for relay 2)

I hope this helps!

Hi,

How did you find out what GPIO pins are? I changed mine to 107 / 108 repecfully but it still not working.

Thanks

I ADB'd into the device, opened a shell and echo'd 1 and 0 into each of the GPIO pins until the relays turned on and off. I followed the instructions in the How It Works section of the readme in this repo https://github.com/Astogems/Home-Assistant-S6E-Tuya-Smart-Panel-Relay-Controls

Thats great news! However, the easier way to do it would be exporting the test APK and decompiling it.

Tuya does a shitty job at code sanitisation hence you literally get the source code. From there, you can easily figure out the GPIO Pins. In fact the S8E might have a knob, it might be possible to reverse engineer that part as well.

If you do manage to export the APK, attach it here and I might be able to take a look as well.

Thanks for this. Am newbie so may take me a little while to get this over!!!

For anyone interested, I de-compiled the test apk on my S8E and found the relays to be at: /sys/class/st_relay/relay1 and /sys/class/st_relay/relay2

Attached is my apk file, if anybody can help, I'm trying to find out how to use the knob and the small display. smatek_s8_23082317.zip

Thanks for everyone's help in finding this information.
