I'd generally recommend against matching sensors directly by ID, because
the IDs aren't stable and they can occasionally get removed and readded
if there is network disruption during discovery.
matching on type and description is probably the way to do it.
What are the exact descriptions of the sensor?

Hello,
i want to build an alert for a specific sensor, i need to check if a
water input of an rlcp (cooled rack) is above a certain temperature.
I manually set the "Max Warn" value in the device properties, so the
sensor will throw a warning, then i created the alert
Condition: sensor_event notequals ok
Association (type AND)
device type in Environment
sensor description match *Water In*
This works, but what i really needed was to specify sensors directly
instead of matching the sensor description, but sadly this didn't work.
I saw that you can specify the senor index in the association and i
used this one from the url
https://observium.mydomain.de/device/device=496/tab=health/metric=temperature/id=*71033*/
Once i tried that, i got no check count unter the "Status / Contacts"
column of the alert checker.
What am i doing wrong?
Best,
Thomas
