Hi! I need a little help with my project…
I have 3 sensors as gauges and a button which turns on a digital output with a relay. The point is that when I upload the code only the 3 sensor work properly but the button don’t. When I upload the code without the sensors the button works. I hope you can help me! thank you all.
Hello, My issue is that I’m using a button widget controlling the gp4 output. But now I tried the button as a virtual with some code still without success…
