I m using several gauges on my dashboard, with different colors for the ranges.  
I would like to set the boundaries from an msg value, but somehow cannot get this to work.  
I tried setting msg.low in a function just before the gauge node, and then in the field that sets the boundary limit: {{msg.low}}.  
Just to check if it was set properly, put {{msg.low}} in the label field as well.  
When testing, I can see the value as label, but it isn't picked up as color boundary.  
Am I doing something wrong?
