One hub for every signal your infrastructure sends.
Sentra Hub aggregates alerts from SMS gateways, IoT sensors, APIs, websites, and vehicle fleets — processes them through intelligent rules — and delivers actionable notifications to your team via push and Telegram.
Input Sources
Monitor anything that sends a signal
Sentra is protocol-agnostic. If it can send an SMS, make an HTTP request, or publish to MQTT — it can feed into the Hub.
SMS Gateways
Native Android gateway app listens for incoming SMS from hardware devices, alarm panels, and industrial equipment — forwarding every message to the Hub in real time.
Website & API Health
Continuous uptime and latency checks for HTTP endpoints, REST APIs, and web services. Get alerted the moment a service degrades or goes down.
IoT Sensors
Ingest telemetry from temperature, humidity, pressure, motion, and custom sensors via MQTT, HTTP webhooks, or direct API — covering industrial, agricultural, and smart building use cases.
Fleet & Vehicle Health
Monitor engine diagnostics, GPS position, fuel levels, and driver behaviour from connected vehicles and asset trackers. Trigger alerts on fault codes or geofence breaches.
Server & Infrastructure
Receive alerts from Prometheus, Grafana, Zabbix, or any monitoring stack via webhook. Centralise all infrastructure events in one place regardless of the source tool.
Custom API Inputs
Any system that can make an HTTP request can send events to Sentra. Open ingestion API with authentication, payload mapping, and custom field extraction.
Platform Features
Built for teams who can't afford to miss an alert
From intelligent routing to two-way Telegram commands — every feature is designed around reducing response time.
Two-Way Telegram Integration
Receive rich alert notifications in Telegram channels or groups. Reply with commands to acknowledge incidents, silence alerts, or trigger actions — directly from the chat.
Intelligent Alert Rules
Define rules using regex pattern matching, severity thresholds, and time windows. Route different alert types to different channels — push, Telegram, email, or webhook.
Sentra Pulse Mobile App
Flutter-based iOS and Android app for field teams. Receive push notifications, browse event history, and acknowledge alerts on the go — with offline support.
Full Event Audit Trail
Every event ingested, every rule triggered, every notification sent — logged with timestamps and context. Complete traceability for compliance and post-incident review.
Live Monitoring Dashboard
Web-based backoffice with real-time event feeds, gateway heartbeat status, alert rule performance, and system health at a glance.
Gateway Heartbeat Monitoring
Each registered gateway reports its status on a configurable interval. Sentra alerts you if a gateway goes silent — before it misses a critical event.
Use Cases
Every industry has signals worth watching
Sentra is sector-agnostic. Here's how different teams use it.
Machine fault alerting
PLC and SCADA systems send SMS or API events when equipment faults occur. Sentra routes critical alerts to on-call engineers via Telegram and push — with full event history for maintenance teams.
Uptime & degradation monitoring
Monitor API response times and website availability. When latency spikes or a service returns errors, the on-call team is notified within seconds with context on what changed.
Vehicle health & geofencing
Connected vehicles stream engine diagnostics and GPS data. Sentra triggers alerts on fault codes, unexpected stops, or geofence breaches — keeping fleet managers informed in real time.
Environmental sensor monitoring
Temperature, humidity, and access sensors feed data into Sentra. Facilities teams receive immediate alerts when conditions drift outside safe thresholds.
Centralised infrastructure alerts
Aggregate alerts from Prometheus, Grafana, Zabbix, and custom scripts into a single hub. One place to see everything — regardless of which monitoring tool generated the event.
Smart metering & grid monitoring
Smart meters and grid sensors report consumption anomalies, outages, and threshold breaches via SMS or API. Sentra aggregates every signal and escalates to the right team before a fault becomes an outage.
Water metering & leak detection
Flow sensors and smart water meters send readings to Sentra. Anomalous consumption patterns or pressure drops trigger instant alerts — enabling rapid response to leaks or fraud before they escalate.
Air quality & pollution alerts
CO₂, particulate matter, VOC, and humidity sensors feed readings into Sentra. When levels breach configurable thresholds, facilities managers and safety teams are notified immediately via push or Telegram.
Soil & crop condition monitoring
Soil moisture, temperature, and irrigation sensors report field conditions in real time. Sentra alerts farm operators when conditions require intervention — reducing water waste and protecting yield.
Chiller & freezer monitoring
Temperature sensors in refrigeration units send readings continuously. If a chiller drifts out of range, Sentra fires an alert before stock is compromised — critical for food safety compliance.
Patient environment & device alerts
Connected medical devices and room sensors report critical readings to Sentra. Caregivers receive immediate push or Telegram notifications when patient metrics or environmental conditions require attention.
Bin fill-level & collection alerts
Ultrasonic fill-level sensors in waste containers report capacity via API. Sentra triggers collection alerts when bins reach threshold — optimising routes and reducing unnecessary collections.
Architecture
Three components, one platform
Each component is purpose-built and works together seamlessly.
Sentra Hub
Web Backoffice
Central management dashboard — configure gateways, define alert rules, browse event history, and monitor system health.
Sentra Pulse
Mobile App
iOS and Android app for field teams. Real-time push notifications, event browsing, and alert acknowledgement on the go.
Sentra Gateway
Android App
Native Android gateway that listens for incoming SMS and forwards them to the Hub via authenticated API calls.
Alerts you can act on — without leaving Telegram
Most alerting tools send a notification and stop there. Sentra's Telegram integration is two-way. When an alert fires, your team receives a rich message with full context. They can reply with commands to acknowledge the incident, silence a noisy rule, or trigger a remediation action — all from within the Telegram chat they're already in.
- Receive structured alert messages with severity, source, and raw payload
- Reply to acknowledge, escalate, or silence — no dashboard login required
- Route different alert types to different Telegram groups or channels
- Audit trail of every Telegram action synced back to the Hub
FAQ
Common questions
- What is Sentra Hub?
- Sentra Hub is a unified observability platform that aggregates alerts from multiple sources — SMS gateways, IoT sensors, REST APIs, website health checks, and vehicle fleets — processes them through configurable rules, and delivers real-time notifications via push and Telegram.
- What input sources does Sentra Hub support?
- Currently available: SMS gateways via native Android app, and custom REST API inputs. On the roadmap: website and API health monitoring, IoT sensors via MQTT and HTTP webhooks, fleet and vehicle telemetry, and server infrastructure alerts via webhook from tools like Prometheus and Grafana.
- How does the Telegram integration work?
- Sentra's Telegram integration is two-way. When an alert fires, your team receives a structured message with severity, source, and payload context. Team members can reply with commands to acknowledge incidents, silence rules, or trigger actions — without needing to log into the dashboard.
- What is the Sentra Pulse mobile app?
- Sentra Pulse is a Flutter-based iOS and Android app for field teams. It receives real-time push notifications from the Hub, allows browsing of event history, and supports alert acknowledgement on the go — with offline capability.
- What industries can use Sentra Hub?
- Sentra Hub is sector-agnostic. Use cases span industrial and manufacturing (machine fault alerting), SaaS and web operations (uptime monitoring), logistics and fleet management, smart buildings and facilities (environmental sensors), IT and DevOps (centralised infrastructure alerts), energy and utilities (smart metering and grid monitoring), water utilities (leak detection), environment monitoring (air quality), agriculture (soil and crop sensors), retail and cold chain (chiller monitoring), healthcare and assisted living (patient device alerts), and smart cities (waste management bin fill-level alerts).
