I am having an issue with the sensor factory status() function returning 0 for an offline probe This is only the case when "Calculate the factory channels and use zero as source value" has been selected. Essentially "Calculate the factory channels and use zero as source value" is causing the status() function to always show probes as online. is this expected behavior? it is frustrating because it prevents me from using the function to ignore offline probes.

I have a channel that is 0 when it is working but I need the ability to get an alert when the channel fails min((Channel(10877,2)<1)/10000,(status(10877)<100)/10000)

When you say offline probe, are you speaking about a sensor or a Remote Probe? The sensors cannot differentiate between when it's in an error status due to not being reachable and when it's in an error state for other reasons, the sensor will return a value of 10,000 when it's in an error state.

I am referring to the sensor being in an error state. When I select "Calculate the factory channels and use zero as source value" which is required to get the formula to calculate when a sensor is down, the Status() also reports a 0 even though the sensor it is monitoring is in an error state.

Unfortunately this is the only way for the zero as source value to function since when a sensor is in error the channel will not be calculated. There is no way for us to change this behavior without fundamentally changing the sensor.

Only when you are ignoring the status of the sensor. When the status isn't ignored and replaced with a 0 it can be useful.

Can you please explain exactly how you are using the sensor factory sensor with your probe(s)?
