Hopefully someone can give me a definitive answer

I am located in a colder environment on the Atlantic coast using a boiler system for heating. Fear is frozen pipes; and the boiler did fail once this year while I was away for an extended period. Just by luck the person who was checking in on the house had his friend with him who is a burner tech.
Currently I have a newer DSC 1832 installed with the EnvisaLink 2DS , and would like to be able to receive a notification if the house temperature falls below a certain range as I do travel a lot, and would like to have some indication if I should send in a contractor to repair / service the boiler should things go wrong.
I noted that the web portal has been updated to include a Thermostat section, but unlike the cameras, does not include any indication of what thermostats are compatible.
1. Is there a comprehensive list of programmable thermostats that work with the EnvisaLink 2Ds or 3?
2. Have these been vetted / tested to confirm they work?
3. Would any of these wireless (or hard wired) thermostats have an alarm system connection to activate the alarm system?
If anyone can give some guidance / information on these it would be most appreciated.
