I’d like to send an email when the gateway loses comms to a device. The sending of the email is no problem, however, I’m not sure what would be the best way to determine the state of communications to a device. Should I interrogate the quality of an existing tag (and if so how?) or is there a way to test the status of the device itself? In any case, I figure I’d write a timer script that would do the test periodically. Thanks for any help.
