Comparing values over time

[FatMax]

I´m looking to debug some issues with floor heating, and was thinking a script comparing two values and notifying me if the value difference is over 2 degrees over a period of 4 hours.

Does anyone have such a script or example? I´m not sure how to store, compare and overwrite the values over time...

You can do it in this way:

1. Event-script for both GA's

Code:

1234567

delta_status = '1/2/3' delta = t1-t2 if delta > 2 then grp.write(delta_status, true) else grp.write(delta_status, false) end

2. Resident-script or Scheduled-script

Code:

12345678

delta_status = 1/2/3 delta_table = grp.find(delta_status) now = os.microtime() time_max = 4*60*60 -- 4 hours if (delta_table.updatetime - now) > time_max then  -- alert function end

Thanks! I'll try this out with some testing.
