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 Mod-
bus 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 a history can be viewed via the ELTAKO Connect app and web
interface. Initial commissioning and confi guration is 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 integrated LED (green/red).
When delivered, the LED fl ashes 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 confi gured or data connection
interrupted), the LED lights up permanently red. The next time data is transferred successfully,
the LED goes out.
If the LED fl ashes red, approx. 5 times per second, there is a HW error and the device must be
replaced.
Initial commissioning via 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 fi rst be assigned.
The current meter values and a history can now be accessed under the menu item 'meters' .
You can fi nd an explanation of the other confi guration options later in the operating instructions.
Initial commissioning and device confi guration 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 fi rst.
After logging in, further confi guration 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.
