I have a UPS that I get an attribute that is presented in seconds. Mostly over 5000 seconds. I want to change that to hours. So the math is simple 5000/60. But how and where is this done? Any exmples greatly appreciated
Assign your attribute to a number variable. Then do a set variable and do variable math. Then you can divide the number by 60

Or divide by 3600 if you want hours.

We’re assuming that you know how to or can find how to:
- Create a variable in RM
- Store a device attribute in the variable
- User variable math to do the calculation
If you are stuck with any of those steps, let us know and post a screenshot of where your rule at the point where you’re stuck so that someone can help.

Well this is embarassing, I am stuck on #1 !
There is no way to add a link to an attribute for a variable (That I can find). The attribute will change and that is what I want to divide by 60 to get the number of minutes the UPS will run everything. I want to put that in a tile on a dashboard. Sorry if I am overlooking the obvious
What Driver are you using for the UPS? It would be much quicker to simply modify the driver to divide the seconds by 3600, giving you hours without needing the complexity of rule machine.
I am using the NUT driver. I thought about that and looked at the Child device code but couldn't figure out how to make that change

Here you go! Give this version a try. I simply added a new custom Attribute that should display the runtime in hours. Simply copy and paste this version over top of your existing one, and upon the next update, you should see the new attribute appear.
Removed version with bug.
See this post for working version

The new attribute doesn't show up 
The result of that runtimeinhours is .87 Is that why it isn't showing up?
I do not have the attribute in the "Select variable to set" I tried to set it up in the Global Variables but there wasn't a way to doit.
Do you see anything in the Events history for the new attribute?
Any errors in the logs?
got this in the log
2022-01-17 03:59:47.697 pm errorgroovy.lang.MissingMethodException: No signature of method: java.lang.Float.Round() is applicable for argument types: (java.lang.Integer) values: [1]
Possible solutions: round(int), round(), trunc(int), trunc(), find(), mod(java.lang.Number) on line 128 (method parseVAR)
line 128 is the hours.hours.round(1)
Instead of changing it to hours why not change it to Minutes?
I updated the code in my earlier post. Give that one a try.
You asked for hours, and thus that is what I attempted to provide. It should provide 1 decimal place of precision, so you should get something to appear. Hopefully I have fixed the error. Let me know.
Same error
Try this version. I found the bug. Simple typo.
