This should be easy

[RASelkirk]

I'm using a "simpletime" node after an inject (timestamp) to get a seconds reading that I want to send to a gauge. The output, no matter what, is always a string. I've tried using a change node to force it to a number, but debug always shows it as a string and gauge does not recognize strings. Like I said, this should be easy but I'm stuck...

You should be able to cast to a number with a jsonata expression like this:

of course change the argument in $number() to the simple time seconds property.

Have you looked at the full msg output of that node? I dont use it but remember seeing it recently had a bunch of stuff added to the msg object

Attach a debug node to the simpletime node and show us a screenshot of the debug output (ensure the debug node is set to show complete message & expand all properties for the screen shot)

the gauge does recognise strings just fine - so what are you actually trying to do ?

PS - you might try to think of a title that mentions approximately the area or node you are struggling with so that folk can filter.

I found had an article similar to what Johannes posted, it's exactly what I'm trying to use. I got it working by changing "payload" to "mysecond" in the change node. Have to be perfect on programming!

I've got some learning to do on gauges. I have my range set 0 to 60, thinking the output from the change node in seconds would "operate" the gauge, but it just pegs to 60 all the time. If I take out the change node and send a string, it does nothing.

well we will need to see a debug from before the change node and also after in order to help further.

Here's a seconds display gauge
