I want to get notification if any of our sensors fail due to malfunction, battery or signal interference. I think the best way to do this would be a trigger on the "Last updated" field, but I can't see how to do it. I can monitor for battery health but that covers only one failure point.
Is it possible to trigger on the "Last updated" field?
If "Last updated" cannot be used in a trigger, how do I create a trigger to sense the health of my various sensors?
Thanks.
