Internet access will typically be needed for each installation to allow measurements taken from meters and sensors to be pushed online to Wattics. In sites where the existing IT infrastructure cannot be reused for logistics or security reasons, the deployment of a
GPRS/3G Router is necessary to provide an independent Internet point dedicated to energy monitoring.
The Wattics WattROUTER is a DIN-rail mounted GPRS/3G industrial router suitable for a
variety of industrial deployments. The WattROUTER requires a sim card that you must source from one of the local providers (e.g. O2, 3, Vodafone in Ireland). You need a broadband data contract with at least 5Go data per month for real-time data.
With the sim card in your hands, the WattROUTER must be conﬁgured to enable Internet access. This procedure must be conducted only once. After that, the WattROUTER will
automatically connect to the Internet when powered up, and will provide a live Internet point to your metering equipment.
4. To remove the SIM card, gently push the SIM card. The card will click out. 2 – Connect the antenna
Screw the antenna into the back MAIN SMA connector. You may use the provided magnetic antenna to receive a better signal in basement or remote locations.
3 – Connect the power supply
1. Connect the WattROUTER to an electrical socket using the power adapter provided, or power the WattROUTER directly from a suitable DC12V/1A DIN Rail DC power supply. 2. The router initialises. The Power LED lights green, the CONFIG LED ﬂashes, and all the LEDs temporarily light in sequence. Then the router activates after a few minutes.
4 – Connect the cat5 cable
Connect the 3G router to your laptop for sim card conﬁguration. 5 – Conﬁgure the 3G router for Internet access
When the router has booted up, browse to 192.168.100.1 in your web browser, enter the username and password below and click login:
Username: root Password: admin
explaining that after you have made changes, you will need to switch the WattROUTER to conﬁg1 for the changes to take eﬀect. This step is explained further later on.
Read the message and click OK.
To conﬁgure the 3G connection, go to the top menu, select Network -> Interfaces.
1. Ensure you have selected the General Setup tab.
2. For single SIM implementation, in the SIM drop down menu, select SIM 1.
3. Enter the correct APN information and PAP/CHAP username and password for your sim card. A PIN may be required for the sim card, but you can leave this ﬁeld empty if unknown. The document below should be used to ﬁnd the correct APN credentials for your sim provider if you don’t know it yet.
Find your APN credentials
4. Click Save & Apply.
Next step is to conﬁgure the WattROUTER to reboot when Internet connectivity fails. To add a scheduled script to ping a remote destination IP and reboot the router on a failure, proceed through the following steps:
Select the System Tab and select Scheduled Tasks A screen opens as below:
Paste in the following: */5 * * * * ping -W 3 -w 20 18.104.22.168 || reboot The ping will be executed every 5 minutes and will run for 20 seconds Submit
Finally, if you have seen the warming message saying that the meter is in Factory
Conﬁguration Mode, you will now need to switch the WattROUTER’s factory conﬁguration ﬁle to the new conﬁguration (otherwise you can directly reboot the WattROUTER). For that go to System -> Backup/Flash Firmware in the top menu.
In the Flash Operations Backup/Restore section, where the text says “Switch to conﬁg1” click on “Switch conﬁg” to make the new conﬁguration the default one. A rebooting message appears to let you know that the WattROUTER will reboot into the new conﬁguration and this may take 2 to 3 minutes.
6. After reboot, to check for Internet connectivity, return to the top menu, and select Network -> Interfaces. The WAN interface will show receive and transmit packets and an IP address. 7. To view 3G connectivity information, select Status -> Mobile Stats. The Mobile/3G
You may run a ﬁnal test to check that the WattROUTER is providing a suitable Internet Access point using your laptop:
Remove the cat5 cable from the Wattics Gateway Unit
Connect the cat5 cable to your laptop (make sure you have DHCP enabled, which is the default settings on most laptops)
Open your web browser (Internet Explorer/Firefox/Chrome)
Try to access wattics.com. If you can then you know that your WattROUTER is working as expected.
You can remove the cat5 cable between the laptop and the WattROUTER, and from now on you have an Internet Access point via the WattROUTER and you will not need to repeat that conﬁguration process again unless you change your sim card provider.
Follow the steps below to verify that your Wattics WattROUTER is conﬁgured correctly: The power supply cable must be connected to the WattROUTER and power source An antenna must be connected to the 3G MAIN antenna slot
Both the POWER and CONFIG LEDs must be on
The sim card has not been removed from the SIM1 slot and the SIM 1 LED is on
Signal strength can also be improved with a better antenna location. Try moving the antenna around closer to wall openings to get a more reliable signal (at least two LEDs on). For
deployments in areas where GSM signal is extremely poor, we can supply indoor and outdoor high-gain antennas with long leads, please contact us at email@example.com to discuss your requirements.
Additional checks should be done if you have diﬃculties in enabling your Internet Access point. You must analyse LED behaviour to understand Internet connectivity status as
The WattROUTER has single colour LEDs for Power, Conﬁg, SIM1, SIM2 and signal strength. When the router is powered on, the LED is green.
Example of power and conﬁg LED activity: power and conﬁg are on The possible LED states are:
Flashing slowing Flashing quickly On
LED behaviour and descriptions
Check how many Signal LEDs are On when the WattROUTER is operational. Poor signal strength may result in frequent disconnections, and a high gain antenna may be needed in environments when GSM signal has low reachability.
The Ethernet port has two LEDs: a LINK LED (green) and an ACT LED (amber). When looking at the port, the LED on the left hand side is the LINK LED, and the ACT LED is on the right hand side.
Ethernet LED activity
Check that the Green LED is On and the Amber LED is ﬂashing when the WattROUTER is operational.
