I am new to openHab and relatively new to Raspberry Pi so my problem is probably an easy one to solve, but it has me stumped.
I have a Raspberry Pi ver 3B+ with openHab 2.5.0 (stable) installed using the openHab preconfigured image.
I was using an online tutorial to learn how to use openHab to monitor/control the GPIO pins on my RPi. I installed the GPIO binding. I created the items file and the sitemap file, and they appear to be OK. The sitemap populates the Basic UI properly. I have a pair of Switch items and a pair of Contact items created in my items file. When I command the switches from the Basic UI, the GPIO do not respond. The log shows that the commands are sent and there are no errors. When I open/close the contacts, the Basic UI does not respond at all.
I went through the prerequisites. I made sure openhab is a member of gpio.
I saw a comment about verifying the operation of the GPIO from the terminal. Just to show my ignorance, would I write a python script to do that?
Any suggestions as to what the problem is?
I’ve seen several comments online about the GPIO binding being one of the more difficult. Is there a better way to control GPIO on an RPi ?
