Node-Red(NR)
is Flow-based programming for the Internet of Things
I have in the past written a lot of posts for Node-RED and the HA implementation makes it easy to interact with HA:s entities.
The best thing is that even if you don't are a skilled programmer, but
like logic flows, you can make really advanced things and it really complements the logic that could be made within Home Assistant(HA).
In this post a will do a quick introduction to what is possible with NR together with HA.
