Select option help

[fares-31]

Well, I have this idea. I want to make a selection option. When I choose "living room," it displays the living room TV voltage gauge. So, I do this.
I create a group on the same page that has the selection option in it. Then I put the gauge group invisible and I put a function that when I click in the living room, it displays the living room gauge. But this method doesn't work. Is there an error?Preformatted text

The message into ui-control node should be in msg.payload
As exampled here Control ui-control | Node-RED Dashboard 2.0

To affect a group you need to add <page_name>:<group_name>.
Example on page i linked to.
ui-control would not need to lbe linked to the gauge node.
