KeyError: "Couldn't find extension field Devialet.CallMeMaybe.dvltServiceOptions" #1
Comments
Hi Floris! This project has been sleeping for a while now, glad to see someone else is interested ;) It should have all the building blocks needed to do what you want, although it's all quite messy and experimental. The most complete example usage is probably in
Volume control should be the one of the easiest use cases, probably using
Fixed this error, which is due to my pretty intense usage of internal protobuf python apis (because a lot of custom stuff in the devialet protobuf usage) that didn't mesh well with the cpp backend. Fixed with a hack for now.
It could absolutely be used to fake a speaker. Both speakers and apps implement the same kinds of interfaces, specifically they are both |

Thanks for your quick response! I have been tryin to get a connection, but apparently some things have changed with DOS2. Right now I only use two Phantoms (without dialog). With my Android phone I try to capture the packages from the new Devialet app. But also ports seems to have changed. Both of my Phantoms use different ports for some reason: Do you still have your Phantom(s)? What is your configuration? |
|
Yeah ports are random and there are multiple ones for all the services that are exposed. Did you have any luck with my pyhon fix? |
|
I'm trying to get some results now, but nothing satisfying so far. Should I connect to the Phantom directly you think? And what port should I use? |
|
At least the error is gone now ;) But it's just refusing the connection... |
|
What is the output ? |
|
The following test: Results in:
And my most positive try so far (port 37703 is always the first port in my trace file): Results in: |
|
I've had a look at the Devialet app binaries, and it looks like the DOS 2 protocol is quite different, for one they are using protobuf 3 now. This repo works with DOS 1 only for now. I haven't updated my phantom, looks like there are only downsides to it (although the spark app does suck)? |
|
Can you send me a capture of chatter between your phantom and app ? |
|
I'm surprised if they also changed the multicast discovery protocol though, I would still expect to see UDP traffic on port 24242 |
|
I sent the capture to your email. When I change to a wifi network without Phantoms, it starts searching with UDP at 224.0.0.251:5353, which seems to be a mDNS discovery(?). |
I think the DOS2 update is fine, Airplay working and Bluetooth (don't know about Spark?). Also nice you don't need a Dialog any more te create a stereo pair. And I use a Sonos connect to get my Phantoms in one app. However, the Phantoms still have a Master volume in my case, so I just need to get this in my Home Assistant app. :-) |

From your capture, it seems they switched the wire protocol to websockets, and are now using new protobufs for the higher level protocol. message BaseRequest {
enum Type {
InvalidType = 0;
Request = 1;
Reply = 2;
Notification = 3;
}
enum SubType {
InvalidSubType = 0;
Open = 1;
Close = 2;
Call = 3;
PropertySet = 4;
PropertyAdd = 5;
PropertyRemove = 6;
Exception = 7;
PropertyReplace = 8;
}
.Devialet.CallMeMaybe.BaseRequest.Type type = 1;
.Devialet.CallMeMaybe.BaseRequest.SubType subType = 2;
.Devialet.CallMeMaybe.TrackingInfo tracking = 3;
.Devialet.CallMeMaybe.RequestTarget target = 4;
.google.protobuf.Any body = 5;
}which looks a bit like the old The chatter looks like: resp |
|
What do you think is the best approach? Perhaps create a new repository with a DOS2 API? (finally it should be in a PyPi library).
Bold are most interested to me, I would prefer to start with this. Some functions don't need to be available for Devialet. |

Hi Henri,
Is there any chance you can help me to create a working volume control for
the Phantoms? I would be really happy if so!
Please let me know.
Kind regards,
Floris.

Hi Henri,
I hope you are doing well. At this time, I have some time to spend on the
Phantom volume control API. Perhaps you are willing to help me a little
further with this? I'm stuck on how the chatter should happen, so just for
the volume control.
Thanks, I hope to hear from you soon!
Kind regards,
Floris.

Hello,
First thanks for this impressive piece of work! Personally I'm very interested in creating a Devialet integration for Home Assistant. Especially volume contol is what I'm interested in. Can you please help me getting started with this? First I have the following issue, any idea how to solve this:
C:\Repositories\etincelle>python client_test.py
Traceback (most recent call last):
File "client_test.py", line 8, in
from dvlt_client import WhatsUpClient
File "C:\Repositories\etincelle\dvlt_client.py", line 15, in
dvltServiceOptions = dvlt_pool.FindExtensionByName('Devialet.CallMeMaybe.dvltServiceOptions')
KeyError: "Couldn't find extension field Devialet.CallMeMaybe.dvltServiceOptions"
Also, do you know if it is possible with this repository to fake a speaker? Because my Devialet Phantom's are on DOS2, I am not able to update my Devialet Dialog unless I have a Phantom (or fake one) with DOS1. Thanks in advance!
