I'd also suggest to everyone looking into HA to take the time to learn Node-RED. After running HA for a year and a half, but only ever creating basic integrations, NR has really unlocked the power of HA for me. Part of it is the tutorials for NR explained the internal data model of HA in a way that I finally get it. Plus just ergonomically, I find NR MUCH easier to deal with than HA's native automation UI.
