Compal-Wifi-Switch

Contributions Only: I no longer have a Compal modem and can therefore not actively work on this project anymore. So all future development will be from pull requests submitted by the community.
What I will do:

• review pull requests
• publish new releases upon request

A command line tool to switch on/off the wifi signal of a Compal-CH7465LG cablemodem.

Wifi radiation should be turned off if not used (better for your health and for IT security reasons). Unfortunattly the Compal-CH7465LG cablemodem does not offer a physical button to switch on/off the wifi signal. There is also no configuration available to switch the wifi signal on/off based on a time schedule.

The compal-wifi-switch tool can switch the wifi signal on/off via a command line interface. The tool can be installed on any device where Python3 runtime is available (NAS, Raspberry Pi, etc.). To schedule compal-wifi-switch you can use any scheduling mechanism (e.g. cron, Synology task scheduler, ...).

For the use within Home Assistant use the custom component hass-compal-wifi.

This module is not official developed, supported or endorsed by Compal.

Installation

Using pip

1. Install python3.7 or higher
2. Install compal-wifi-switch with pip install compal-wifi-switch.
3. Run compal-wifi-switch with compal-wifi-switch --help.

Without pip (e.g. on Synology DSM)

1. Download package from PyPi (tar.gz) to your server.
2. Run the following commands:

# Install
user@dsm:~> tar xfv compal-wifi-switch-<version>.tar.gz
user@dsm:~> cd compal-wifi-switch-<version>
user@dsm:~/compal-wifi-switch> python3 setup.py install --user

# Run
user@dsm:~> python3 ~/compal-wifi-switch-<version>/compal_wifi_switch/main.py --help

Usage

General syntax

usage: compal-wifi-switch [-h] [--version] {status,switch,reboot} ...

Compal-Wifi-Switch configuration

optional arguments:
  -h, --help       show this help message and exit
  --version, -v    show program's version number and exit

command:
  {status,switch}
    status         shows the current status of the cablemodem
    switch         switches the wifi state of the cabelmodem  
    reboot         reboots the cabelmodem      

Command switch

Usage

usage: compal-wifi-switch switch [-h] [--band {2g,5g,all}] [--guest]
                      [--pause PAUSE] [--host HOST] [--password PASSWORD]
                      [--verbose]
                      {on,off}

positional arguments:
  switch
  {on,off}

optional arguments:
  -h, --help            show this help message and exit
  --band {2g,5g,all}, -b {2g,5g,all}
                        band to switch power state for (default = all)
  --guest, -g           activate guest network while switching ON wifi
  --pause PAUSE, -p PAUSE
                        number of seconds to pause after wifi state change
                        (default = 60); when the pause is too short, the
                        following modem commands may block forever
  --host HOST           host name or IP of compal cablemodem, or use env
                        variable COMPAL_WIFI_SWITCH_HOST
  --password PASSWORD   password of compal cablemodem, or use env variable
                        COMPAL_WIFI_SWITCH_PASSWORD
  --verbose             verbose logging

Example

To enable the wifi signal for the 2GHz band including the activation of the guest network, use the following command:

> compal-wifi-switch switch on --host 192.168.0.1 --password <YOUR_PW> --band 2g --guest

Switching wifi ON (band = 2g)
Wait 60s till wifi state is changed ...
Finished.
