pyharmony

Python library for connecting to and controlling the Logitech Harmony Link

Protocol

As the harmony protocol is being worked out, notes are in PROTOCOL.md.

Status

• Authentication to Logitech's web service working.
• Authentication to harmony device working.
• Querying for entire device information
• Sending a simple command to harmony device working.

Usage

To query your device's configuration state:

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip 192.168.0.1 show_config

It really helps to assign a static lease and hostname for your harmony on your router interface, so you don't have to keep looking up the IP.

Some other commands you can invoke via command line:

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip my_hub_host start_activity 'watch movie'

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip my_hub_host sync

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip my_hub_host show_current_activity

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip my_hub_host turn_off

# to send device commands, look in show_config for the device and
# command name, you can use either the device id or label with --device
#
PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip my_hub_host send_command --device 'yamaha soundbar' \
    --command PowerToggle

For full argument information on the command-line tool:

PYTHONPATH="." python harmony --help

TODO

• Figure out how to detect when the session token expires so we can get a new one.
• Figure out a good way of sending commands based on sync state.
• Is it possible to update device configuration?
