Node RED is still unwieldy for the masses, as easy as it is for a consumer to install, it’s not necessarily as easy to use.
Consumer grade automations built on node-RED? I suppose it depends on the market, but most people aren’t going to want to fiddle with it, I suspect.
A plugin for Chrome might be able to take off though, or some killer mobile app, but it needs to run on a cheap phone and control things without having to keep track of loops and logic and variables and all the fun stuff.
