How to identify an missing Unknown Node when importing a Flow ?
1. unknown: ui\_text
2. unknown: ui\_chart
3. unknown: ui\_gauge
I have found the flow here:
[Efergy Energy Meter or Energyhive Api](https://flows.nodered.org/flow/5e1d72d1f490ab98dfc447b06145ad80)

They look like the nodes from `node-red-dashboard`.
I assume that you don't have the dashboard installed?
To install - `npm install node-red-dashboard` or install from the palette manager.
