My event log shows that my item state is changed to undefined every 10-11s, which then means after that its switched to off.

Can not figure out where the problem is, I know my item are correctly set up, see GPIO, but where is the item state stored, that has to be the problem:)

Without using peristence, it’s stored in your machines ram.

Thanks, was probably something wrong with my persitance file then, however it works really nice now after reinstalling openhab.
