Hai, I have a problem with my dashboard. the gauge cannot show the data. I have used change to change the string data to number, but it's still not working.
this is the flow
How are you converting it to a number in the change node? And how is the gauge configured?

I understood the gauge node should accept a string containing a number, but I may be wrong. Feed the message you are sending to the gauge node to a debug and show us what it says.
I think you have to set {{msg.payload}} instead of {{payload}} 
If it doesn't work, try to link your change node to a debug node and post here the result (showing all msg object structure, not only the payload )
Thank u, it is working! Thank you guys for giving me the answers
