I've been using the UDI Portal with the ISY V3 Alexa skill for several years to control my devices with spoken commands. I also have several A/V Virtual devices that control a Roku TV and a Windows PC with Windows Media Center.
All the A/V Virtual device functions under the Basic, Volume and Playback tabs work perfectly.
However, I cannot get the 8 inputs under Input Select tab to respond to spoken commands on any of the A/V Virtual devices I have created.
The spoken syntax is supposed to be: "Alexa, change input to <input name> on <device>".
Alexa responds with "I don't know how to set <device> to that setting" on the first attempt and with "" on subsequent attempts.
Example: I have an A/V Virtual device with the device spoken "media center" and input-1 named RECORDED. When I speak the command, "Alexa, change input to recorded on media center" the response is "I don't know how to set Media Center to that setting".
If I then speak the command for another input on the same device, the response is a soft "bong bong" which shows up as "" in the Alexa app voice history.
I experience this behavior with the A/V Virtual devices for both the Roku TV and the Windows PC with Windows Media Center.
The A/V Virtual device for the Roku TV uses network resources for all 8 input selects and the Windows PC uses programs for all 8 input selects. The network resources and programs work fine when triggered manually through the management console. I'm pretty sure my A/V Virtual device names are okay because functions like On/Off, Mute/Unmute, Volume Up/Down, Channel Up/Down, Play/Pause/Stop, etc work fine.
I've tried different device spokens, different input names, deleting and recreating the A/V Virtual devices. I've even tried just waiting for a few weeks since some folks have reported that strange Alexa integration problems sometime clear up on their own after waiting for a few days. Nothing seems to work for input select.
I've searched the forums here but I can't seem to find any reference to this issue. Any ideas?
