I've been tinkering with Node-RED in HA and I run into a wall.
If I would have 14 rooms, with in each room a thermostat, I would add 14 thermostat widgets/groups to the dashboard. One thermostat functionality for each room. But I seem to get stuck to create one widget and reuse it 14 times. Or to add 14 dashboard thermostats to one group? Something, so that I don't have to program 14 thermostats and edit 14 thermostats to make one change
So, I think this just not doable with the dashboard nodes. A head-ace further I tried the dashboard template node. With it I can create an Angular.js widget.
I feed it an array with the different thermostats. It then itterates over the array to render the different thermostats.
You are right it is not doable by using the dashboard widgets.
I circumvent the problem and save dashboard real estate by using a drop down widget to select a room or item and use one group of widgets to control the selected room or widget.
I then have obe tab per room to show only the controls for that room.
And I use ui-table to get an overview of all thermostats or other things.
