Telemetry-Initiated SMS: Instant Alerts from Devices, Sensors and Alarms
Telemetry SMS sends an automatic text the moment a device, sensor or monitoring system detects an event. It provides fast, direct communication that cuts through noise and reaches the right people immediately — ideal when every second matters.
What Is Telemetry-Initiated SMS?
Telemetry SMS is the automated transmission of data from remote or inaccessible points to a monitoring system that triggers an SMS alert. When a threshold is crossed, an input changes state, or an alarm activates, your system posts data to our API and Cosmic SMS delivers a text to the people who need to know. No specialist apps required — any mobile phone can receive the update.
Why Use SMS for Telemetry Alerts?
SMS is built into every handset, requires no app install and works even when data coverage is poor. Delivery is quick and reliable, messages are concise, and recipients can act immediately. For operations teams, facilities, security, IT and health & safety, SMS provides a low-friction, high-reliability alerting channel.
Accessible by Design
Visual or audible alarms alone can be missed. SMS adds a clear, personal notification that supports deaf and hard-of-hearing users by delivering critical information directly to the handset. With clear language and optional reply keywords, recipients can acknowledge or request help in real time.
Common UK Use Cases
Fire, intruder and lone-worker alarms; environmental conditions (temperature, humidity, water ingress, CO/CO2); refrigeration and cold-chain monitoring; power and UPS events; generator status; plant, HVAC and lift faults; data centre thresholds; flood and river level sensors; utility and substation telemetry; agricultural monitoring; healthcare and personal alarm triggers; transport and depot alerts. If a device can raise a signal, it can send an SMS.
How It Works with Cosmic SMS
Your device, gateway or software posts an alert to our SMS API with the message text and recipient list. We route and deliver instantly, fan-out to groups if required, and return delivery receipts for audit. You can also ingest replies (2-Way SMS) to confirm acknowledgement or collect follow-up data, all accessible via the API and web portal.
