I have googled this forum and wider - but nothing helps!
Node-Red portal is there - but when I configure it , to get the MQTT feed that is already on the box (the emon topic) - the graphical interface is stuff saying ‘connecting’.
Probably some simple thing I;m over-looking… but I’m a good googler and found nothing. I did find out of date stuff on node-red on OEM (eg that it comes with a default working config)
I want to have a play with Node-red talking to my emonPi (with a view to later adding feeds from some IoT things - Shelly
I have a fresh emonPi set up on OEM-purchased hardware - with 4 emonTH. All work fine.
I installed node-red on the same Pi. From the upstream node-red resources.
the portal works =-I can drag MQTT things into it - but it never connects.
The MQTT is on local host -the same box.
I can access the portal from my laptop (ubuntu 20)'s browser.
Maybe there is a firewall thing… preventing node=-red talking to the local=host MQTT…
