Need help making pin D1 available for 8 relay module

[mrhutchinsonmn]

Is there a way to utilize pin D1 for my 8 relay module with this or a modified sketch? I understand from research that the serial commands are getting in the way but I am not sure how to work around this and need pins 8-13 for my radio. (Powering via vin)

#define RELAY_ON 0          // GPIO value to write to turn on attached relay
#define RELAY_OFF 1         // GPIO value to write to turn off attached relay

@mrhutchinsonmn which Arduino are you using?

[mrhutchinsonmn]

Ardunio Nano

[mfalkvidd]

@mrhutchinsonmn I think you use this

#define MY_DISABLED_SERIAL

Documentation: https://www.mysensors.org/apidocs/group__SerialDebugGrpPub.html#ga77b235511106d59e4ee2a1d9a919b49e

[mrhutchinsonmn]

Will this mess with data sent to my home assistant controller, or only disable serial monitor and usb?

@mfalkvidd Got it! Had to put on top of sketch to get it to work.. Thank you!
