My Minotaur Engineering IFF1 Precision Freezer Failure Sensor Died

[CPrince]

Anybody have a recommendation for a freezer failure sensor?  My Smarthome Minotaur Engineering IFF1 Precision Freezer Failure Sensor failed and sent my about 2000 emails in a few hours.  At first I thought it the IO Link.  I swapped out the IO Link and it went crazy again.

The sensor closes the Sensor Input on the I/OLinc.

Sounds like you traced the problem. As a added test you may try and disconnect the freezer sensor connection to the I/OLinc and see if things change. The Sensor LED on the I/OLInc may also be flickering. The input sensor circuit is not too tolerant of noise.
