In 2019 I got a TV2 system from 2DI that contacted me when temperatures went out of range, low or high, on refrigerators and storage rooms. It used cabled probes. I was happy with the system, less happy
with my institution’s IT, with whom I was forever negotiating to allow the 2DI system to contact me (email and phone). I never did get it working reliably.
I am now in a new building and interested in the responses to this.

If you are using monitoring devices for your 4C flammable-rated refrigerators, and these devices are able to either send an email or (better) place a phone call, I would be very interested in learning what
you use and your experience with it. I would like to be able to add monitors to ~6 flammable refrigerators while we essentially close down floors for several weeks for construction. We do not have 'built in' monitors for these refrigerators.
It is pretty cheap and easy to do this for nonhazarous material refrigerators but my initial lead is turning out not to be either...
