OK. I find the easy way....   1. Create virtual device 2. Choose set of buttons 3. Set label name: Power ON (for powering up the AVR) 4. Enter in text box for string to send: GET http://"DENON IP"/MainZone/index.put.asp?cmd0=PutZone_OnOff%2FON HTTP / 1.10x0D0x0A0x0D0x0A (Replace "DENON IP" with your IP of Denon AVR!!!) 5. That's all...Works great    Add more buttons for more commands...
