![]() But it is rather laborious to implement, and the ISY is slow to execute it. MV13, MV16, MV19, MV22, MV25, etc) that are invoked by ISY programs as the user selects different volume levels. As a workaround, I have a list of about 10 separate network resources each with its own volume level (eg. That increment is too small to be useful when dispatching user-invoked volume commands using the ISY because of the delay introduced by the ISY. ![]() I can confirm that I have found no way to implement volume up/down commands in greater increments than 0.5dB. will IH/RPi be stable enough for this unattended location vs Global Cache. Harmony seems not to permit device level macros and has very limited repeates at the device level, only custom button press assignments can be macros, which IH may or may not interface with and, ii. If I can create the command in Harmony with enough repeats sent by Harmony that would work too. ![]() IsyHelper (IH) enables the ISY to interface w my Harmony Hub. Because I am doing this on a keypad it looks like I have two options:ġ) Use a Global Cache to convert back to IR with required repeats built into the command, orĢ) Test IsyHelper for this. I've searched here, AVS, Remote Central etc and not found a way to do: "increase by 5db" etc. That level of volume change is barely audible so as to make that function useless because you cant send enough repeats fast enough to be functional.60 seconds holding a button doesn't cut it with Mrs. If you invoke Volume Down, it changes by 1 unit ie goes from 40 to 39. Its "relative volume", i.e increase/decrease that is the issue. ![]() Yes that is what I meant by "absolute volume", which can be done just as you say. Not sure if this is what you meant by absolute volume. Your command would be MV40 if 40dB was the level you wanted. Look at the pic which is a snip of the service manual for AVR-3312CI/AVR-3312. Not sure of the exact model you have and whether or not this is applicable, but you could try this. the C escape character '\r').Ĭreate a network resource with the following configuration:Ĭlick Update, Save, Save again, select the resource and click Test.Īny other command that your receiver supports can be put in the body. In this example, I will be using the "ON" "PoWer" command which is the string "PWON" followed by carriage return (i.e. the IP address of your Denon AV Receiverįind the command you want from aforementioned control protocol document. get to the ISY994i's Admin Page->Configuration->Networking->Network Resources tab Things you'll need that I won't document here: How to Create a Network Resource That Sends a Command to an AVR from an ISY994i As a reference, this is the protocol that the LinuxMCE project uses to control Denon receivers. The commands (but not the connection details) are also the same for both RS232 and Ethernet. Therefore, I expect Denon to maintain a level of consistency for this control protocol across different models. The protocol document reads like an API spec. While the protocol document references a particular model of Denon receiver (AVR-3808CI), the protocol seems to work the same for both models that I have tried to control (AVR-2808CI and AVR-2113CI, purchased 5 years apart). (in case that link goes dead in the future, google for "Denon AVR control protocol"). Denon AV Receivers have an official control protocol.
