The scripts are currently copied from the repo manually and periodically need to be copied again to get the latest. I have updated some scripts recently and the 000_startup_delay.py script has been removed. I haven’t seen a need for this script in a long while, so you could remove it. This may need to go back in if people report issues with it not being there, which may be the case for people running DSL rules too. I will create a release when the updates are all pushed, update the beta Jython addon, and then get some forum posts out. I am working on including the core scripts inside the addon, to make updates easier.
It does not look like requests and its dependencies were installed into /etc/openhab2/automation/lib/python. If you find where it went, just copy it in there. You could also copy it from your Python2 directory. Please open a new topic to discuss further, as this does not pertain to the addon.
