Hello,
After upgrading from OpenHAB 2.x to OpenHAB 3.x I would like to use GPIO inputs on my Raspberry Pi. When I apply voltage to my GPIO input (in this case GPIO-10) the switch item stays on. That’s good. But when I disconnect the voltage the state of the input is constantly changing ON-OFF-ON-OFF… (my screen recording video is here) in an infinite loop. Outputs are working fine (tested on a LED). I am using resistors but no in pull-up or pull-down setup.
Am I missing something? What’s wrong with it? Thanks for taking time to look into this.
I was following and using examples from this guide: GPIO - Bindings | openHAB
The use of channels and the use of Switch instead of Contact item in GPIO binding is new thing for me. In OpenHAB 2.x I was not using channels and I was using Contact instead of Switch for input. It worked there.
Here are my files and setup in OpenHAB 3 (on openhabian):
demo.things:
Thing gpio:pigpio-remote:sample-pi-1 "Sample-Pi 1" [host="::1", port=8888] {
Channels:
Type pigpio-digital-input : sample-input-1 [ gpioId=10]
}
demo.items:
Switch SampleInput1 {channel="gpio:pigpio-remote:sample-pi-1:sample-input-1"}
demo.sitemap:
sitemap demo label="Main Menu"
{
Switch item=SampleInput1
}
- Platform information:
- Hardware: Raspberry Pi 4B, 2 GB RAM, 16GB micro-SD
- OS: Fresh install “openhabian-pi-raspios32-v1.6.5” + GPIO binding add-on + pigpio daemon
- openHAB version: 3.1.0

Thank you. I was not using pull-up/pull-downs in older version. It worked.
