Connect Your Device Fleet
Enterprise-grade MQTT for sensors, gateways, and edge computing. Built on the protocol that powers industrial IoT worldwide.
Built for IoT Workloads
MQTT is the industry standard for IoT. CloudSignal makes it easy to deploy and scale.
Offline Resilient
QoS 1 and 2 ensure messages are delivered even when connections drop. Perfect for unreliable networks.
Low Bandwidth
MQTT's binary protocol minimizes data transfer. Ideal for cellular, satellite, or metered connections.
Secure Communication
TLS encryption and topic-level ACLs protect your device data from unauthorized access.
Sub-100ms Latency
Critical for real-time control systems. CloudSignal delivers messages faster than HTTP alternatives.
Built-in Analytics
Monitor connection health, message throughput, and device status from the dashboard.
Protocol Native
MQTT is the standard for IoT. Works with every device SDK and gateway out of the box.
Industry Solutions
From factories to hospitals, CloudSignal powers IoT across industries
Industrial IoT
Monitor machinery, track production metrics, and enable predictive maintenance.
Smart Buildings
Connect HVAC, lighting, access control, and energy monitoring systems.
Fleet & Logistics
Track vehicles, monitor cargo conditions, and optimize routes in real-time.
Healthcare
Connect medical devices, wearables, and remote patient monitoring systems.
Simple Device Integration
Connect devices using any MQTT client. Python, C, JavaScript, or your device's native SDK.
- Works with Raspberry Pi, Arduino, ESP32
- Industrial PLCs and gateways
- REST API for cloud-to-device messaging
- Retained messages for device state
