On-call alerts by text
Last updated 3 October 2026
Thermofi texts heating and cooling alerts to the people our customers put on call for their buildings. If your workplace has added you as an on-call contact, sign up from your own phone:
Text ALERTS to (478) 242-6687
What happens next
- If a customer has added your number, we reply to confirm which buildings you will
get alerts for, and alerts start then:
Thermofi: Confirmed for heating & cooling alerts at [building name]. Msg frequency varies. Msg&data rates may apply. Reply HELP for help, STOP to opt out. - If no customer has added your number yet, we tell you so and send nothing else. Ask your building manager to add you, then text ALERTS again.
- We never text an on-call contact before they text us.
What you will receive
- Operational alerts only. A zone that is too cold or too warm, humidity high enough to risk condensation, heating or cooling equipment running without effect, and devices that have stopped reporting, each followed by an all-clear when it resolves. No marketing.
- Message frequency varies. Alerts are sent when a monitored condition changes; a quiet building may go weeks without one.
- Message and data rates may apply.
- Reply STOP to opt out at any time. Reply HELP for help, or contact ken@thermofi.ai or 617-733-4370.
By texting ALERTS you agree to the Terms and Privacy policy. We do not sell or share your phone number or opt-in data with third parties for marketing.
