The Hidden Sonos Web Interface

Sonos Connect Getting started

Sonos controllers interact with the players through the HTTP protocol. It is actually possible to directly use this underlying interface to communicate with the players without being limited by the feature set made available in the controller.

In order to access this interface, you first need the IP address of the player you want to interact with. It is listed in theĀ  "about my Sonos system" menu of the Sonos controller. We'll refer to it as <sonos_ip> below.

Status Screen

The status screen can be used to gain insight into the player setting, its hardware, and its environment. It is available at the following URL:

http://<sonos_ip>:1400/status

The screen displays a large collection of submenus that you can explore at your leasure. Many of these menus such as 'dmesg', 'netstat', and so on will be familiar to Unix users since they display the result of the corresponding command (Sonos players run the Linux operating system internally).

Support Screen

The support screen is available at the following URL:

http://<sonos_ip>:1400/support/review

It will print one link per player, as well as one link for the controller and one for the network matrix.

Player Name 1 (RINCON_000E5812345671400)
...
Player Name n (RINCON_000E5876543211400)
Controller
Network Matrix

The information available under each player name is very similar to the one provided by the status screen of that particular player. I haven't yet looked carefully into the Controller menu.

The last link, the network matrix, is extremely useful to diagnose wireless connectivity issues. It looks like this:

Sonos network matrix

Colors in the left column denote the ambient RF noise seen by the Sonos unit. Colored cells in the body of the matrix indicate the state and strength of the 'tunnels' across the mesh:

OFDM signal levels go from 0 to 5, where 5 is best and 0 is way too low to get a reliable connection. Noise floors are typically in the [-80 -110] range, where -110 is considered excellent and -80 bad.

If a unit isn't sending or receiving data wirelessly (i.e. the corresponding row and column in the matrix are both gray) the wireless adapter can be turned off to save power and reduce wireless interference.

Rebooting the player

Accessing the following URL will trigger an immediate reboot of the player:

Troubleshooting Network Connectivity

Sonos offer 3 traditional network debugging tools (ping, traceroute and nmblookup) from this URL:

Controling the WiFi network link

The WiFi link can be enabled or disabled through the wifictfl URL. If the WiFi is turned on, it will use different frequency channels based on the region in which the player was sold. For example, the use of channels 12 through 14 is not allowed in the United States. You can update this setting at the following URL:
