- acidburnNSA 6y agoI have not. I do it all in yaml still, which I feel like I like. I've seen some pics of node-red graphs and it looks pretty slick though.
- jcims 6y agoIt's super slick. Runs pretty good in docker on the Pi if you just want to tinker without making a mess. I'm using it to do process control for a small fractional distillation apparatus. It's doing temp monitoring, production monitoring (by weight) and using a PID loop to manage heat input. Takes a minute to figure out how it works but once you get used to the message format you can stack on functionality extremely quickly. With MQTT adding functionality from other devices is super easy too. Overall have had a really good experience with it. My only complaint is that it's not multi-threaded, so if you have a process that blocks (e.g. the dallas 1-wire library for reading temp sensors) then you'll stall the flows. Most of those issues have simple workarounds though.
