I've got Node-RED installed as a docker and it can see states on devices I share with it from my Hubitat hub at the time of deploying a change but if a state changes in Hubitat, the state doesn't update in Node-RED because the POST isn't getting through.
This prevents my flows from starting because they don't know a state has changed.
I've been told to look at whether the ports are open on my node-red docker to allow posts from the hub, the hub sends it's posts to: http://192.168.1.2:1880/hubitat/webhook__
How do I ensure 1880 is 'open'? I'm running the docker with its own IP on br0.
Or am I missing something?
