Network Requirements for Spiio sensors

To ensure your Spiio sensors are able to connect to the Internet smoothly, you should understand the types of network that are supported, how they maintain WiFi security, and how they communicate through a firewall. This will help you advise your end-users and troubleshoot their network-related technical queries. Don’t hesitate to get in touch with Spiio if you encounter any problems at:


Every sensor is designed to use 802.11n WiFi operating in the 2.4GHz band. They are compatible with older 2.4GHz 802.11b and 802.11g networks.

Some 802.11n routers are marked ‘dual band’ — they can operate in both the 2.4GHz and the 5GHz bands, sometimes simultaneously. These routers should be set to provide a 2.4GHz network, either in place of a 5GHz network or alongside it.

For security reasons, no sensor can be configured to operate as a WiFi hotspot (access point).

WiFi Channels

The Spiio sensors can rarely have troubles using WiFi channels 12 and 13. Please ensure the wireless router is not set to channel 12 or 13.

WiFi Security

Every sensor is capable of determining what kind of security — WEP, WPA or WPA2 — is being used by the network it is attempting to connect to. It supports all of these ‘consumer’ security mechanisms, including non-password protected WiFi connections.


The Spiio sensors can receive a WPS (WiFi Protected Setup) code and use it to securely log into your router.

Removing Your Password

If the sensors  is configured to connect to a password-protected WiFi network but the security level is subsequently downgraded by removing the password, the sensor will no longer connect to the network. To re-connect, the device must be reconfigured.

This is by design. It is intended to prevent sensors (and other devices on the network) being ‘captured’ by a rogue WiFi access point masquerading as your network router. It can do this by transmitting the same SSID as your network but at a higher signal strength, but without the password, which the assailant does not know.

Enterprise WiFi

Sensors do not currently support enterprise-level WiFi authentication, 802.1x, which requires that you log in with a username and password as well as the customary SSID. A sensor will not be able to connect in such an environment at this time.

Captive Hotspots

The Spiio sensors do not support networks which present an HTML form in which the user enters login details before network access is granted. Some consumer routers use this approach, but it is most commonly encountered with public hotspots and some guest networks in corporate environments.


The sensors will only make outbound connections, so firewall configuration is only required if the firewall stops outbound connections. This is rarely the case in consumer routers, but commonplace in corporate environments.

Sensor communications make use of the following ports, which need to be open through a firewall:

31314XInitial sensor-server connection
993XFallback sensor-server connection
80XSensor firmware updates

The sensors will attempt to connect via TCP port 31314. If this fails, they will attempt to use TCP port 993, which is typically open by default for email traffic. They do not use UDP.

Port 80 is used to request and transfer sensor firmware updates. This port is typically open by default for HTTP/HTTPS communications.
