},| notification | payload | description |
|---|---|---|
| VOLUME_GET | - | Getting current volume |
| VOLUME_SET | 0 - 100 | Setting Volume to number. 0 is mute and 100 is maximum |
| VOLUME_UP | {upDownScale: NUMBER} or null for default value |
Volume up by upDownScale |
| VOLUME_DOWN | {upDownScale: NUMBER} or null for default value |
Volume down by upDownScale |
| VOLUME_STORE | null or 0-100 |
Storing current volume and setting the volume to number.If payload be null, volume will not be changed. (just stored) |
| VOLUME_RESTORE | {faded:true or false; upDownScale:NUMBER} | Setting volume with stored previously |
If volume is changed or VOLUME_GET is called, the current volume as result will be notified by CURRENT_VOLUME notification with payload=0-100.
