Hi Losant Support,
Quick question: is there a simple expression which is able to nullify values from reading an attribute on a time-series?
For my example, I have an attribute represented as an integer measurement which is expected to be greater than zero. Our system currently expresses a failed measurement as 0 instead of null.
I’m hoping to filter the 0 measurements from the time-series for this attribute, as it provides a clearer picture of the actual physical measurement to our end user. I’m hoping to do this within the time-series itself, as most of the processing is done external to any Losant workflows and is effectively fixed for now.
Below is an example of the data in question - with frequent ‘0’ measurements indicating failure.
Is the following possible with a simple expression in the time-series block?
Thank you for any insights you may be able to provide!
