How to create a combined value relay condition?
How is it possible to create a combined condition for the relay contact at the D103?
I want the relay to close (ON) when Total Power (d.TW) is > than Total Reverse Power (d.TrW) and open (OFF) otherwise
BAD, I'M UNSATISFIED
the answer doesn't help.
i still don't know how two values can be compared and set as condition for the relay output control.

You can set the conditions in the device web-settings.
See the CONDITIONS section in the manual.

In your case, you should understand that at one point in time one of the values will be equal to 0.
If [W]>0 then [rW] at this moment is equal to 0.
And if [rW]>0 then [W]=0.
Accordingly, the conditions will be simple.
[W]>0 => RELAY ON
[rW]>0 => RELAY OFF
Below is an example from the device settings.
Thank you very much for your reply.
However, in my application there is a single phase solar system on one phase connected which causes that Total Power can be > 0 and at the same time Total Reverse Power also >0
Yes, if these are different lines, then maybe.
But such a condition cannot be set in the device settings, sorry.
You can collect data and control the relay via the API.
In this case, it is possible to write a script yourself and control the relay under any conditions.
