You are correct, and I to can not get the gauge to change title . Even using the info from this page Gauge ui-gauge | Node-RED Dashboard 2.0
I have tried using both ui_update.label or ui_update.title.
This seems to be a bug, I would check the Github page for the node. If there is no issue raised I would raise one
@joepavitt I also get some weird cache issue as in image below, no msg.ui_update is sent, but the button node seems to be sending it
Set change node to send msg.ui_update.title

Then tried to send msg.label and the msg.ui_update object is sent by group button node.
