Purpose-built hardware for real sites
Wireless sensing, energy metering, environmental monitoring and retrofit-ready devices designed for reliable deployment in the field.
Hardware for your site
Measure electricity and temperature, collect readings from existing meters, and connect industrial equipment. Choose the family for your application, then use its datasheet and configuration options to specify your installation.

-
ZEM
Measure electricity where it is used.
Monitor three-phase circuits with pre-calibrated current sensors. Bring electrical measurements from distribution boards and equipment onto the wireless site network.
- Measurement
- Three-phase electricity metering
- Current sensors
- Split-core CTs and flexible Rogowski coils
- Communications
- Zigbee wireless mesh
-
ZDR
Measure demand. Respond locally.
Combine three-phase metering with local control for demand-response projects. Choose the controller and current sensors to suit the response service and installation.
- Measurement
- Three-phase electricity metering
- Control
- Relay switching; capabilities depend on configuration
- Communications
- Zigbee wireless mesh

TES
Temperature data from the places that matter.
Monitor pipes, equipment and storage conditions with battery-powered wireless probes. Choose the probe style, cable length and number of channels for the installation.
- Sensing
- Single or dual external temperature probes
- Probe options
- Waterproof, pipe and general-purpose steel
- Power
- Replaceable battery
-
ZPC
Bring existing meters into your network.
Collect pulse outputs from water, gas, heat and electricity meters. Send readings wirelessly to the Gateway without replacing the meter.
- Input
- Meter pulse outputs
- Channels
- Single or dual channel
-
ZIO/ZVO
Connect the instruments you already use.
Bring analogue measurements from flow, pressure and other industrial transducers onto the wireless network. Choose current-loop or voltage inputs to match the instrument.
- Current input
- 4–20 mA transducers
- Voltage input
- 0–10 V transducers
- Channels
- Single or dual channel
-
ZHM
Read an M-Bus meter wirelessly.
Connect one wired M-Bus meter to the EpiSensor wireless network. Collect utility readings through the Gateway, with an integrated relay for suitable valve-control applications.
- Meter connection
- One M-Bus meter per interface
- Valve relay
- 1 A at 250 V AC, resistive load
- Enclosure
- IP67
-
ZMB
Connect serial equipment to the wireless network.
Read and write Modbus RTU equipment through a local wireless interface. Integrate existing meters and controllers without running a data cable back to the Gateway.
- Protocol
- Modbus RTU
- Interface
- Serial connection to the equipment
- Power
- Integrated mains supply

Built for real sites.
A Gateway and a ZEM installed beside distribution boards. Choose sensors and interfaces for the measurements, environment and communications at your site. Their datasheets specify the installation requirements.
- Wireless mesh
- Zigbee connects wireless devices to the Gateway. Range depends on the building and installation.
- Enclosures
- Check each product’s protection rating, mounting and operating conditions for its location.
- Local logging
- On-device storage varies by product. Retention depends on the readings enabled and reporting interval.
- Encrypted connections
- AES-128 protects the Zigbee network; TLS protects supported connections to external services.
Complete the system
Sensors report to a Gateway. The Gateway runs Edge.
Every device on this page is one layer of a three-layer system. Choose the sensors for the site, add one Gateway, and Edge gives you the data, automation and integrations locally.

Gateway
ZGW-20 supports up to 250 devices, depending on the sensors and reporting load. Wireless radios, cellular and other connections depend on the selected hardware and installed integrations.

Edge
Edge runs dashboards, data and automation locally on the Gateway. Connect external platforms when needed; remote access, notifications and exports need their network connection.
