While testing, I copied the node-RED flows.json to a different instance of node-RED.
It deployed okay, however temperature, LQI, thermostat setting etc do not update on the dashboard.
Discovered that the node-RED node 'mqtt in' (top left of flow) had the wrong output type set up.
It showed 'auto-detect (string or buffer)' it should be set to 'a parsed JSON object'

Changing this fixed the issue.
