Step 2: If your wireless network coverage is sufficient, there may be a problem with your router. To find out if this is the case, please follow these steps:
Are you using a wireless network with a frequency of 2.4 GHz?
In order to be able to integrate the Sense device into your wireless network, the network needs to use a frequency of 2.4 GHz. The device will not work with a frequency of 5.0 GHz. You can view and change the frequency in your router’s settings.
Is your private wireless network secured with WPA/WPA2?
GROHE Sense does not work with open wireless networks. It requires a wireless network that is secured with WPA or WPA2. Your private wireless network therefore needs to be protected by a password that has at least eight characters.
Is MAC filtering activated?
MAC filtering is a method for protecting wireless networks. If it is activated, the wireless network router will only give approval to known/registered devices. MAC filtering is not normally activated by default. It usually needs to be set up manually. If you have activated MAC filtering, please deactivate it or add the MAC address of the GROHE Sense to your router’s list. To find out the MAC address of your GROHE Sense, download the app for testing your wireless network and initiate the device’s integration mode (blue flashing LED) by inserting the batteries. Then connect the device to your smartphone. The app will display the MAC address of your device.
Are the ports 433 (HTTPS) and 80 (HTTP) open?
Ports are network connectors. They enable your wireless network to communicate and also facilitate other services. Ports 433 and 80 need to be open in order to establish a connection between GROHE Sense and your wireless network. In most cases, these ports are open by default. If this is not the case, please read your router’s manual.
Is DHCP activated on your router?
DHCP is a communication protocol for communications between devices and the wireless network. It needs to be activated in order to use GROHE Sense. DHCP is normally activated by default on routers. Visit the following web page for an explanation of how to find out if DHCP is activated and how to activate it: http://www.wikihow.com/Configure-a-Router-to-Use-DHCP
Does the router support IPv4?
The IPV (Internet Protocol Version) is the way that your router communicates with the devices connected to it. There are different versions: IPv4 and IPv6. The GROHE Sense device communicates using IPv4, so the wireless network router also needs to support IPv4. In most cases, routers support both IPv4 and IPv6. You can check and change this in your router’s settings. This web page explains the process: http://testingfreak.com/change-enabledisable-ipv4-ipv6-computer-windows/
