[Nhcoll-l] freezer-alarm systems

[Opitz, Cindy]

Hello!
Does anyone have experience to share or recommendations for freezer-alarm systems that send notifications when pre-set temperatures are reached? We have a new walk-in freezer (-20) and would like to install an alarm system that alerts us when the temperature gets too high. Our old freezer (may it rest in peace), had only an audible alarm, but we had to be in the room to hear it. I would love to have something that sends me a text message or email instead. The freezer installers want to sell us a fancy control unit that would allow us to monitor/adjust operation from afar, in addition to notifying us when temps get too high, but it seems complicated and like much more than we want or need. I know there are temperature alarms available that are either hardwired via telephone or internet network, or that operate using wifi. Can anyone recommend what has or has not worked for them or good companies/systems to consider?
