Sorry folks for another dumb question.
I've been away and come back to this task.
To simplify some flows, I realised that I am making my life difficult because I am getting sensor data from sensors, but WHAT they are may change.
eg: Outside temp may become Pool temp.
So, rather than having the devices send their "names" and have to edit all that when one is changed, I was thinking that on THAT side of things, I get "temp1", "temp2", "temp3" and so on.
Then, when their data is received and "sorted" (collated?) a node adds a bit to the msg..... and the gauge/chart/what ever who gets it gets the name to show from the message.
I've got that part working and want to "expand" it to the entire GROUP.
So the gauge/chart can be named but say I have sensors and they are giving data for "room1" and someone decides to change "room1" to "garage".
Rather than edit the name via the editor, can I inject something into the TEMPLATE NODE and it changes the name of the group?
I know this node can change the justification of the title in the group. But the actual text?
I know it is going to be easy, but I have looked. Seems my time away has not helped with me recalling all the names/terms.
Thanks in advance.
