Need Freezer sensor

Just want ti know if temp exceeds X, get notified. Looking for a working freezer temp sensor. I see many BT + gateway versions but would prefer to use something Someone already has in play vice finding a solution.

Post 29 is my contribution. Been using that setup for over a year, might have changed the Zigbee module battery once. The temperature sensor just keeps on doing it's job.
