Just tried in the "online regex tester and debugger" and it hates the forward slashes, tells me they need to be escaped.
F : { name:'F', regexp:/\bF\
-?\d+\.\d+)\b/i, value:'', duplicateInterval:3600, unit:'°', pin:1, graph:1, graphValSuffix:'F', graphOptions:{ legendLbl:'Temperature', lines: { lineWidth:1 } }},
What am I doing incorrectly?
