Hi,
really I'm not sure that this should work currently, because this limits fetched from DB returns as "" (empty string).
:D
I will do additional tests with this conditions, but I think for this case also possible use:
sensor_limit ne
(yes, also without last value)

Hi all,
Thank you for adding this option JWe also had some false positives due this missing function.
I changed some alerts now and it’s working fine so far.
Example test condition (require all conditions):
sensor_value ge @sensor_limit
sensor_value ne 0
sensor_limit notnull
Mit freundlichem Gruß

Does “sensor_value notmatch“ work?
That’ll end up being ‘ if $sensor_value != “” ‘ or there abouts
I’ve just added “isnull” and “notnull” operators (last argument isn’t used), but you need to be running r10226 for that.

Hello,
In alerting, do you have the option to match "null" value?
For example, to match/not match the sensor with sensor_limit_warm = null value.
My goal it's create alerting with "sensor_value gt @sensor_warn" but excluding when sensor_warm is "null" in database. Because that's create false positives.
Thanks!
