Energy Monitoring
Wireless, revenue-grade energy monitoring for commercial and industrial sites. Deploy in hours, integrate with any platform, and scale without limits.
Metering-Grade Precision
Accurate and reliable energy data you can trust
The ZEM wireless electricity monitor delivers Class 1 accuracy as standard, with the ZEM-63 achieving Class 0.5S (IEC 62053-22) revenue-grade accuracy. Split-core and Rogowski current transformers are included and factory-calibrated for immediate deployment.
Deploy Fast. Stay Connected.
Install once, monitor forever
EpiSensor's ZigBee Pro mesh network eliminates the need for complex cabling runs. The self-healing network automatically reroutes data if any node goes offline, ensuring continuous monitoring without manual intervention. One gateway supports up to 100 nodes and 1,000 sensor feeds.
Open Architecture
Open platform, no lock-in
The ZGW-10 Gateway runs on a quad-core ARM processor with Ubuntu Core, delivering enterprise-grade compute at the edge. Data flows to your platform of choice via HTTP(S), MQTT, or FTP(S) in standard JSON or CSV formats. Over 50 pre-built integrations are available out of the box.
Beyond Electricity
Monitor every utility from a single platform
EpiSensor's wireless sensor network covers electricity, water, gas, temperature, and more — all managed through one gateway.
Electricity
ZEM wireless 3-phase monitors with Class 0.5S accuracy. Up to 36 data feeds per device covering power, energy, voltage, current, and power factor.
Water & Gas
ZPC pulse counter wirelessly captures output from existing water, gas, and heat meters — no meter replacement needed.
Temperature
TES probe sensors, ZHT ambient temperature and humidity sensors, and ZTS air quality monitors for complete environmental monitoring.
Any Meter
ZMB Modbus interface connects existing wired meters wirelessly. ZIO and ZVO interfaces support 4–20mA and 0–10V signals for flow, pressure, and more.
