denonavr-cli 3

denonavr-cli is a trivial CLI client for Denon AV receivers based on the denonavr library. Its biggest advantage is receiver autodiscovery, so you don’t have to specify the IP address.

When run without arguments, it scans the network for AVRs. If it finds exactly one, it displays its status:

$ denonavr-cli
Power: ON       Volume: -54.0 dB         Input: HEOS Music

Note that if there are more AVRs on the network, you need to specify the host explicitly:

$ denonavr-cli -H 192.168.1.6

After every call, the executable caches the host used, eliminating the autodiscovery delay for subsequent commands (but -H always overrides the cached value). If the cached host is no longer responding, it is discarded and autodiscovery is reenabled. You can also manually clear the cache via:

$ denonavr-cli --host-cache=reset

To see the available commands and options:

$ denonavr-cli --help

In general, commands without additional arguments print the current status in a machine-readable format, e.g.:

$ denonavr-cli volume
-54.0

The commands that alter the state generally print the new value after performing the action:

$ denonavr-cli volume up 4
-50.0
