Display a value from a Node-Red node on Lovelace as graph?

Third party integrations Node-RED

Hello fellow HA users.

I´m using this node “node-red-contrib-msg-speed”, to track a possible watter leakeage. If durring the last 10 min, had 12 ticks from the reed connected to the watermeter, an allarm is triggered. I would like to be able to monitor over a longer period the evolution of the output of this node.

I have tried with an osciloscope on the node red dashboard, but it was rendering the page unresposive with 1 day of data. I was thinking that maybe a sensor displayed in a grapf mode on Lovelace dashboard would offer me the needed information.

But I have no ideea, how to get the data from the node written to a sensor, so please guide me to be able to find the solution.

Thanks and regards,

Look under the Homeassistant panel in the NodeRed Pallette. Look for a node type ‘entity’

The entity node will create either a switch, binary sensor or sensor entity in HA. Pass what you want to the node and then work with the sensor in HA as you normally would…

You’ll need to install the nodered companion in HACS to create entities.
