Build virtual power plants and energy management systems with EpiSensor sensors, Gateways and Edge software. Connect real-world equipment, visualise data and automate. Run Edge locally with no cloud service or subscription required, or deploy it in the cloud.
Edge runs locally on the EpiSensor IoT Gateway
Our complete sensor product range
EpiSensor designs and manufactures high quality wireless sensors for energy management and Virtual Power Plants: electricity monitors, meter interfaces for water, gas, heat, oil and steam, industrial analogue and digital signal sensors, pulse counters, M-Bus and Modbus interfaces for legacy equipment. They all communicate with the Gateway.
EpiSensor designs and manufactures high quality wireless sensors for energy management and Virtual Power Plants: electricity monitors, meter interfaces for water, gas, heat, oil and steam, industrial analogue and digital signal sensors, pulse counters, M-Bus and Modbus interfaces for legacy equipment. They all communicate with the Gateway.
Edge supports standard Zigbee 3.0, so thousands of off-the-shelf switches, lamps, sensors and meters from over 400 vendors can join the same secure, wireless mesh network beside EpiSensor devices. You can view data and set up automation rules with devices from different manufacturers, even across different wired and wireless protocols.
The Gateway also supports thousands of third-party LoRaWAN devices for long-range, battery-powered monitoring and control across campuses, large sites and utility infrastructure, where a local mesh does not reach.
Connect the Gateway to the building management system already in place. Edge reads and writes BACnet points, so heating, ventilation and lighting appear beside the wireless sensors and can be controlled from the same rules.
Wired Modbus talks to existing plant equipment, BMS and SCADA: meters, HVAC, heat pumps, solar inverters, EV chargers and battery storage systems. Wireless Zigbee devices such as the ZDR demand response controller can sit alongside them in the same data model, so Modbus and Zigbee devices coexist on one site and existing assets join without new hardware.
Every device, whatever protocol it uses, has access to the same tools for configuration, data and automation. A Zigbee sensor can command an asset over Modbus, a meter can feed a digital twin, and automation rules run on site without any connection to the cloud.
EpiSensor Gateways support on-board cellular modems that work worldwide. Add your own data SIM card and get secure, high bandwidth remote access without interfacing to on-site IT systems.
Edge supports open Internet-native communications protocols like HTTPS, MQTTS and FTPS. It has a comprehensive API for managing every aspect of the system, and an IDE based on Node-RED for building custom integrations to local or cloud systems. Use EpiSensor Core to manage a fleet of Gateways: secure onboarding, health monitoring and remote management over MQTTS that works behind NAT and firewalls.
Edge runs on the Gateway and puts devices, data, dashboards and automation in one application, close to the systems they serve.
Build a dashboard around the work you do. Combine live values, trend charts, gauges, equipment status and controls, then arrange and resize the widgets for your team or a shared display.
More about dashboards
A plant dashboard. The compressor load stays high because a maintenance override is on.
Edge presents wired and wireless devices through one data model. Monitor their sensors and create automation rules across protocols and physical connections, from a wireless temperature sensor to a Modbus meter or building controller.
More about devices
Respond to a threshold, a schedule or a change in equipment state. Notify the right people, call a webhook or control a device. The rule runs locally, on site.
More about automation
Compare sensors and time periods in one workspace. Choose a date range, show or hide series, and adjust each chart’s axes and presentation. Send a useful view to a dashboard or export the selected data to CSV.
More about data
Battery and solar over 24 hours. Positive battery power is discharge, negative is charging.
Organise a site into buildings, floors, rooms and assets. See live conditions in their physical context, with room views and a spatial model that make the site easier to understand.
More about buildings
Combine sensor inputs into calculated values. Use them in dashboards and automation, just like physical readings, then share the data through authenticated APIs and open export formats.
More about calculations
A calculated sensor averaging two climate sensors.
At EpiSensor, we focus on six qualities we believe every connected device should have. We engineer our products for the real world, because our partners’ businesses depend on accurate data and on secure, reliable systems that are easy to use, communicate over open protocols and scale smoothly across thousands of sites and assets.
Protected at every layer, from field devices and local networks to software updates and remote access.
A complete sensing chain designed for consistent, traceable measurements.
Designed for plant rooms, rooftops, switchboards, and difficult retrofit environments.
One operating model, from a single device to a distributed estate.
Designed to keep operating through intermittent connectivity, imperfect sites, and long service lives.
Open protocols and documented interfaces keep customers in control.
Start with a single measurement point or connect a mixed-protocol energy site. Every EpiSensor device arrives in Edge with the same tools for configuration, data and automation.
