notification if voltage drops below xx Volt for more than yy seconds

[BartSr]

Hi,
After having the steep learning curve of dzVents it's much easier for me to use than LUA.
But now I faced a triggercondition I dont' have a solution for.
The P1 gives among others also Volt-value.
I have a server running supplied by UPS. But I need to stop the server in a proper way if power mains fails as the UPS is about 20 minutes in service after power failure.
I expected to use L1 < 200V to be sufficient to trigger a notification but it appears that for whatever reason it happens to get a voltdrop to about 35V several times a day.
Now I could set the trigger to L1 < 30V. This will work fine but imho it's better to get a notification if voltage is below e.g. 200V for longer than 1 minute.
How can such a ytrigger be programmed (if possible).

Thanks for your thoughts.
-Bart

You can use the history function of dzvents. Store the voltage in an history array and do some avarage calculations on that. Then act on that.
See for example viewtopic.php?t=38305
