Thanks Colin!
I spend hours watching node-red Essentials.
I made the runtime msg.runtime
And the downtime msg.downtime
In de debug menu I see the values in seconds from msg.runtime and msg.downtime
I made a function node where I want to calculate the uptime by: runtime minus downtime .
Like the example: Percent calculation
But it doesn't work properly
I have no idea why. It's driving me crazy!
What am I doing wrong?
