I have Node-RED running on a raspberry pi that is hardwired to my router. My PC is also hardwired.
My internet recently went down and I could not get Node-RED to load (http://192.168.1.100:1880/) on my PC. Is this normal ? It was weird because other pages being served from my Pi would load.
Well, could be you have some nodes that are "looking for the net"
You have a thermostat depending on an internet connection, right?
Yes , you are correct. I thought it would just show an error or not connected ?
Won't open at all.
Node-RED itself "should" be ok totally disconnected. If there is a node that is blocking it then that ought to be investigated as it ought to still allow the flow to run.
Is there an error log I can check to see where it is stopping ?
the console when you run Node-RED is the log - but I would suspect that unless we are lucky the node wouldn't report anything... but it's worth a look.
Which 3rd party nodes have you got installed may be easier to guess from.
it's probably this one node-red-contrib-tcc-honeywell as I just installed it and it connects to a website.
