Sonoff Basic - GPIO does not work

[Przylepzwm]

Homekit does not control GPIO Outputs for the built-in LED and relay. The built-in button does not change the state of the switch in homekit.

Detailed steps to reproduce it

-flesh fullhaaboot.bin using NEMUMCU FIRMWARE PROGRAMMER - success. -configure wifi network and install HAA - success -adding MEPLHAA Script configuration - success -adding the homekit accessory - success -Relay control - does not work (only changes state in homekit)

As a test, I used a simple project created in the Arduino IDE to check the hardware - everything works (LED and relay).

MEPLHAA Script {"c":{"io":[[[12,13],2],[[0],6]],"l":13,"b":[[0,5]]},"a":[{"0":{"r":[[12]]},"1":{"r":[[12,1]]},"b":[[0]]}]} Used device

Read WIKI, invert "i": in "c":{...}

Thank you for the suggestion. According to WIKI for sonoff, Invert LED should be "1"- and this is the default value. Do you suggest changing to 0?

I will add that the JSONs I tested (there were several of them) come from WIKI device database or HAA Json Configurator

It looks as all GPIO does not want to work with this software. Earlier there was Ravencore v1 (for thermostat) and it was fine. Using another simple project I am able to control GPIO out on pin 12 and 13 as well.

Yes. Invert from default. Default is invert. Set "i":0

Relay and build-in button works! Thank you so much I have one more question: right now the status of the LED is always On. I tried to add output config to make the LED ON only as relay is controlled:

{"c":{"io":[[[12,13],2],[[0],6]],"l":13,"b":[[0,5]],"i":0},"a":[{"0":{"r":[[12],**[13]**]},"1":{"r":[[12,1],**[13,1]**]},"b":[[0]]}]}

But still the diode is always On. Can you take a look at what I am doing wrong? Thx!

[xrust83]

gpio13 in Sonoff basic uses as notification LED. if you need to make it status on/off then take it from sonfig "c": there is another option. diode 2-contact red/green. connect it to gpio2 or gpio14 from the boards version.

https://tasmota.github.io/docs/devices/Sonoff-Basic/#serial-flashing

simultaneous use as a diode for errors and for relay status is not possible, this may cause interruptions in operation and code

{"c":{"io":[[[12,13],2],[[0],6]],"b":[[0,5]]},"a":[{"0":{"r":[[12],[13]]},"1":{"r":[[12,1],[13,1]]},"b":[[0]]}]}

Thank you very much for the explanation and best regards.
