Hi all, I was just wondering if anyone has any experience with calling external scripts from openHAB’s rules and scripting language. For example possibly having a rule which uses the openHAB timers to call a python script every X seconds. If not is there anyway to execute shell commands from openHA…

What version? I know there was whitelisting implemented in 2.5.2 for exec. I do not know if that affects other external script calls.

Thanks for the resources Scott. I have been messing around with the executeCommandLine Action and have got it running external scripts that I have in python3. The code looks something like this in case anyone else was interested and is located in the rules/ directory of openHAB. The permissions on t…
