Eltako ZGW16WL-IP Modbus Meter MQ TT Gateway Over IP
Only skilled electricians may install this electrical equipment otherwise there is a risk of fire or electric shock!
- Temperature at mounting location: -20°C up to +50°C.
- Storage temperature: -25°C up to +70°C.
- Relative humidity: annual average value <75%.
ZGW16WL-IP
- Modular device for DIN-EN 60715 TH35 rail mounting.
- 2 modules = 36 mm wide, 58 mm deep.
- IP interface either via WLAN or LAN.
- The WLAN connection uses the 2.4 GHz frequency band.
- The LAN connection is via RJ45 connector with 10/100Base-T
- Only 0.9-watt standby loss.
ZGW16NI-IP
- Modular device for DIN-EN 60715 TH35 rail mounting.
- 2 modules = 36 mm wide, 58 mm deep.
- IP-Schnittstelle über WLAN.
- Die WLAN-Verbindung nutzt das 2.4 GHz Frequenzband. Only 0.8 watt standby loss.
- ZGW16WL-IP and ZGW16NI-IP hereinafter called ‘ZGW16-IP’.
- Gateway with IP interface for ELTAKO Modbus electricity meters.
- The IP connection is via LAN or WLAN. The gateway transmits data from any ELTAKO Modbus electricity meter via the MQTT protocol and REST API.
- The data is transferred from the ZGW16-IP to any external MQTT broker.
- For more details about MQTT see www.mqtt.org.
- The current meter values and history can be viewed via the ELTAKO Connect app and web interface.
- Initial commissioning and configuration are possible via the ELTAKO Connect app and web interface.
- Firmware updates are done via the web interface. A REST API is available via the device‘s online product page.
Controls
The ZGW16-IP has a rotary switch with positions 1-10 and an integrated LED (green/red). When delivered, the LED flashes green, although the rotary switch must not be in position 1 or 10. Once the initial commissioning is complete, the LED goes out.
Factory reset
If the rotary switch is set to position 1 or 10, the LED lights up green
continuously. If the rotary switch is turned back and forth from position 1 5
times within 10 seconds, the ZGW16-IP is reset to factory settings and the
delivery status is restored.
Error indication
If data transfer to the MQTT broker is not possible (e.g. MQTT not configured
or data connection interrupted), the LED lights up permanently red. The next
time data is transferred successfully, the LED goes out.
Initial commissioning via the ELTAKO Connect app
- After the power supply to the ZGW16-IP has been established, a WLAN access point is provided.
- SSID: Eltako-ZGW16-IP
- Password: zgw16-ip
After connecting to the WLAN access point, the ELTAKO Connect app can be
started. The ZGW16-IP is automatically searched for and displayed in the
ELTAKO Connect app. When delivered, an access password must first be assigned.
The current meter values and history can now be accessed under the menu item
‘meters’. You can find an explanation of the other configuration options later
in the operating instructions. Initial commissioning and device configuration
via web interface
Via WLAN: After the power supply to the ZGW16-IP has been established, a
WLAN access point is provided.
- SSID: Eltako-ZGW16-IP
- Password: zgw16-ip
The IP address of the device is 192.168.4.1 (WLAN) or 192.168.5.1 (LAN) Via LAN (ZGW16WL-IP only): when delivered, the LAN port has the IP address 192.168.5.1 To do this, enter http://192.168.5.1 (LAN) or http://192.168.4.1 (WLAN) in the address. In the delivery state, an access password must be assigned first.
- Connection to the WLAN access point
- SSID: Eltako-ZGW16-IP
- Password: zgw16-ip
After logging in, further configuration can be performed using the menus:
- system
- network
- MQTT
- devices
- Modbus
If there is no access to the website for 4 hours, the user is automatically logged out.
System
Here the ZGW16-IP can be assigned a suitable name with up to 16 characters. It
is also possible to carry out a FW update, change the access password and
reset the device to the delivery status.
The system time can be set via NTP (only with an existing Internet connection) or manually.
network
The LAN configuration is only possible with the model ZGW16WL-IP. If WLAN is
to be used, a connection to an existing WLAN (Station-Mode) can be configured.
This deactivates the access point of the ZGW16.
MQTT
Under ‘MQTT’, a specific MQTT broker can be defined as the target address for
the electricity meter data. mqtts:// or mqtt:// can
be used. The port can be freely selected in the range 1 – 65535. If provided
by the broker, a certificate can optionally be stored. The name for the MQTT
topic (Default ZGW16-IP) can also be adjusted.
The maximum data rate depends on the network quality and the response time of the broker.
Devices
Under ‘Devices’ the detected ELTAKO Modbus electricity meter is displayed on
the RS485 bus with the bus address and the meter type.
The current meter values and the history are visible by opening the device display. The historical data is stored locally on the ZGW16-IP
Technical data
