I was a fan of Webcore back in my SmartThings days. I mistakenly thought somehow that Webcore was running locally on Hubitat. I guess I should have been more aware of the fact that the URL was pointing to the cloud.
So, I use Rule Machine and I have lots of RM, RM legacy and simple automation rules. They all work great, but Webcore takes control to the next level. I ended up creating a LXD Ubuntu container on one of my servers and I installed the Webcore Github project which is the same version as the Webcore in the cloud.
I was able to backup all 59 of my Webcore pistons running in the cloud and import them all into my locally hosted Webcore. There were a few annoying steps, but I can report that in the end, everything is working great.
If anyone wants help with this, I am willing to help you along.
