Why no freeze sensor alarm behavior options?
I would like to see an option in the device settings for freeze sensors to allow the user to select either "secret alert" or "alarm" when the sensor is triggered. As it stands now, if the temperature at the sensor is outside the allowed range, an "always on" alarm is automatically triggered and monitoring staff are notified to call the user's phone. While this is a good procedure in many cases, I would prefer to have the option to have a "secret alert" sent to my phone.
In my case, I am monitoring the temperature in my storage shed with one of my freeze sensors. If it goes below freezing or above 120, I'd like to be alerted but it does not require urgent action and I don't want to be alerted in the middle of the night by a loud alarm or phone call. On the other hand, I also have a freeze sensor in my well house where I have a heater to protect the pipes and equipment in winter. For that, an "alarm" setting is appropriate if a freeze is imminent. So it would be nice to have the alarm behavior be selectable for each freeze sensor - just as it is for each entry sensor.
Comments from other users about this topic (work-arounds, or something I don't know about) would be appreciated.

The switching part can be thermostatic switches, or a couple of cheap heating/cooling thermostats, wired in-series. Advantage of the cheap thermostats is you could adjust your upper and lower limits.
For thermostatic mechanical switches, there is cheap Chinese stuff to be had for $2.51 each, pick your temperature. At that price, you could run several in-series to decrease the odds of a fail-badly.

For the cold side thermostat, you would get a special low-temperature thermostat, which look to run $25-30.

Not sure that one will have the required normally-closed contacts, so might have to re-purpose a replacement (or salvaged) refrigerator thermostat.
Curiously, looks like a water heater lower thermostat would be the right choice for the hot side. It is adjustable and will go to 125 F where a wall thermostat won't, and only costs $6.

The temperature alerts are impossible to live with. My greenhouses are set to warn of temps below 40 degrees. Once an alert, it repeats every hour all day and night long. It is impossible to go to bed with this system because it'll wake you up all night long. There should be an option to not repeat alarms until the temperature reset above the trigger point occurs. I only need one freezer alarm to know to go take care of it. But alarms all night long means nobody sleeps.
