A powerful, rugged and secure embedded computer with an IoT app store and many wired and wireless communications interfaces: ZigBee, Wi-Fi, Bluetooth, 4G Cellular, LoRa, GPS, CANbus, RS-485

EpiSensor Gateway

Powerful hardware

  • Quad-core 1.5GHz ARM Cortex-A72 Processor (based on RPi CM4)
  • Ubuntu Core operating system with a secure IoT app store
  • Wide operating temperature range, silent and low-power with passive cooling

Industrial interfaces

  • Wide Area Network: Gigabit Ethernet, 3G/4G/5G Cellular, Wi-Fi, GPS
  • Local Network / Serial / Sensor Network: Bluetooth, ZigBee, RS-485, CANbus, USB, LoRaWAN
  • Industrial / Legacy Protocols: Modbus, OPC UA, BACnet, CAN

Developer friendly

  • Comprehensive HTTP API for monitoring, automation and remote management
  • Supports software packaged as ‘snaps’ for Ubuntu Core with OTA updates and transactional updates
  • Minimal attack surface, automatic vulnerability scanning, and snapshots/rollbacks for reliable software updates

Open standards

  • Export data in open web-style formats like JSON, CSV and XML
  • Supports modern Internet communications protocols like HTTP(S), MQTT(S) and (S)FTP
  • Compliant with enterprise-grade network security policies
EpiSensor Gateway Nodes List. Connect multiple nodes to each EpiSensor gateway to build scalable energy monitoring solutions.

Manage Nodes

Monitor and manage large networks of EpiSensor wireless nodes from the Gateway’s web interface.

Take actions like restarting or factory resetting a wireless node, upgrade firmware, sync, and enable and configure each ‘sensor’ (which is an individual feed of data) to report data the way you want it to.

Data View

The data view on the Gateway is intended to assist installation teams with confirming that data is being produced correctly.

Expecting the Total Active Power on a 3-phase supply to be 100kW for the last 30 mins? Access all of the sensor data in the Gateway from your laptop or mobile device to confirm a system has been installed and configured correctly, before leaving site.

Layout View

Visualise how nodes in the wireless mesh network connect back to the Gateway in real time.

Identify areas of poor wireless coverage, monitor signal strengths, adjust power levels, and confirm that you’ve build a reliable wireless network before leaving a customer site.

System Architecture

EpiSensor’s Gateway routes data from networks of wireless sensors to the software platforms of our customers and partners – no sensor data passes through EpiSensor servers in the process.

The Gateway can be deployed within a corporate network, or isolated automation network, behind NAT and firewalls. The data the system produces is yours, and yours only.

Data Export

Export any feed of data in the Gateway to 3rd party servers and applications, or other apps running locally on the Gateway.

Choose from a variety of ‘web style’ communications protocols and data formats, like CSV via FTP or JSON via HTTP(S) – as well as messaging protocols like MQTT(S).

EpiSensor’s Gateway is compatible with a variety of cloud based IoT services like AWS IoT Core and Azure IoT hub.

Manage the Gateway’s Ethernet, Wi-Fi and Cellular interfaces from the web interface and API. Set IP addresses, configure DNS and DHCP, cellular APN and authentication. Configure SSL for encrypted communications to the Gateway’s web interface.

The built-in connection watchdog can poll an external server to verify connectivity and take action to redial, reconnect or reboot if a connection fails. You can also configure industry-standard networking features like NTP time sync and syslog server logging.

CM4 Inside

Built on the Raspberry Pi Compute Module 4, an industrial-grade ARM computer module from Raspberry Pi.

With CM4 inside, you get best-in-class performance, low power consumption, a future-proof hardware platform, and compatibility with the world’s best open-source software.
