Has anyone seen any of these actually used in a system?

seems completely useless since a typical weatherproof pull doesn’t have actual electronics so it doesn’t really have a temperature rating, and the monitoring module for it will be located in a temperature controlled area somewhere. there might be an application for it, i just can’t think of one.
I’ve used their heated strobe covers in freezers before though.
