Fire a Trigger when one or more item reach a threashold

[marcolino7]

Hi,
I have a number of Items, tracking the battery level of all my sensors of my Home Automation system.
They are more than 35 sensors and I would not like to create one single trigger for each single sensors.
All sensors are under one single Host (my Home Automation Server) and all sensors have same application calles "Sensor Battery".
I would like, if possible, to create only one trigger, and fire it when one of the sensors reach 20% battery, this will save me from create and mantain more than 35 triggers.

Any way to perform this?

Many Thanks
Marco

Generally the way this is done is to do a low level discovery so that you create an item for each based on an item prototype, and a trigger for each of those. LLD is where a lot of the power of zabbix templates reside.

If you have hard coded it instead, you can build a trigger where each item is listed, separated by a bunch of "or" so any one will fire.
