Idea: use python to directly generate rules files

You can’t put every use case in every page of documentation. See How to get started (there is no step-by-step tutorial)

So having a familiarity of what OH can do is important. That’s why we emphasize reading the docs so much. That page doesn’t say anything about getting web pages but it does take about openHAB Actions. And there is a page in the docs that goes over all the built in actions including the sendHttpGetRequest.

To be successful with any home automation system you have to be able to piece together tutorials and reference guides that address on small party of what you are trying to achieve because there never will be an end to end tutorial for your specific system. Your system is unique.
