Cannot change TV power state #14

Open daciand opened 5 years ago

daciand commented 5 years ago

First of all, thanks for the plugin!

I have a Panasonic TX-55FZ800E and, even if the TV shows up fine in the Home app, I am not able to change its power state by clicking on it. The current state is correctly reflected in the app, but as I said, I cannot change it. By using the TV Remote 2 app on my iPhone, I am able to change its power state, which I guess it means that the TV can be started remotely. It may also be worth mentioning that the TV is connected to my local network via WiFi (802.11n, 5 GHz band).

My config.json looks like this: { "accessory": "Panasonic-TV", "name": "Panasonic TV", "ipaddress": "192.168.0.153", "inputs": [ { "id": "TV", "name": "TV", "type": "TV" }, { "id": "HDMI 1", "name": "Apple TV", "type": "HDMI" }, { "id": "Netflix", "name": "Netflix", "type": "APPLICATION", "appID": "0010000200000001" } ] }

In the homebridge log I can see the following lines each time I'm clicking on the TV's icon from the Home app: May 19 20:50:03 raspberrypi homebridge[29149]: [2019-5-19 20:50:03] [Panasonic TV] Powering TV on... or May 19 21:07:10 raspberrypi homebridge[29149]: [2019-5-19 21:07:10] [Panasonic TV] Powering TV off...

Am I doing something wrong or the TV is not supported by the plugin? Thanks!

Issue is still reproducible with plugin version 6.0.1. I'm using latest iOS and latest version of homebridge.

LeBaron90 commented 5 years ago

try to reinstall the plugin (delete it and install it again, not just overwrite), maybe that helps. I have nearly the same settings like you, and it works on my tv. I checked your config on https://jsonlint.com and it looks good…

daciand commented 5 years ago

I did try doing that: sudo npm -g uninstall homebridge-panasonic-viera-tv --save sudo systemctl restart homebridge.service sudo npm install -g homebridge-panasonic-viera-tv@6.0.1 sudo systemctl restart homebridge.service

But still doesn't work: May 21 08:42:45 raspberrypi homebridge[17460]: [2019-5-21 08:42:45] [55FZ800_Series] TV is off May 21 08:43:07 raspberrypi homebridge[17460]: [2019-5-21 08:43:07] [55FZ800_Series] Powering TV on... May 21 08:43:43 raspberrypi homebridge[17460]: [2019-5-21 08:43:43] [55FZ800_Series] TV is off

Maybe some of the API implementations have been changed for the 2018 series?

Hi! Thanks for making me aware of this issue. Thanks to @LeBaron90 for the suggestion and sorry that it still doesn't work. I'll be sure to have a look at this!

I'm having the same issue with a Panasonic 49FX740, which is also a 2018 model TV. Also the same as @daciand , I can control it with the Panasoic TV Remote 3 App on my iPhone, including power on/off.

The TV shows in the Home App, but state is often incorrect and none of the switches work: on/off, or changing inputs, etc.

Here's a wee snippet of the logging of actions from the Home App when running homebridge -D

[5/07/2019, 12:25:59 AM] [Living Room TV] TV is off
[5/07/2019, 12:26:04 AM] [Living Room TV] Powering TV on...
[5/07/2019, 12:26:26 AM] [Living Room TV] Switching to TV
[5/07/2019, 12:26:34 AM] [Living Room TV] Opening Netflix app
[5/07/2019, 12:26:39 AM] [Living Room TV] Switching to Chromecast
[5/07/2019, 12:26:42 AM] [Living Room TV] Powering TV off...

None of these actions have any effect.

I did notice that when setting up the Panasonic TV Remote 3 App on iOS for the first time a pairing PIN code was required (displayed on the TV, needed to be keyed in the App.) Is this possibly part of the issue? Does homebridge-panasonic-viera-tv need to authenticate somehow?

Thanks for all your hard work on this, it looks really promising and obviously works well for others!

bartong13 commented 5 years ago

@g30r93g I've done a bit more analysis by taking a tcpdump of network traffic while using the Panasonic TV Remote 3 App on iOS. It appears that the app is sending encrypted commands, presumably using a key that was created at the time I "paired" the App with the TV (when it prompted for the PIN).

If it's of any use I can share the pcap file with you to look at in Wireshark, but I think this encryption may render your plugin useless for this model of TV (and presumably any other recent Panasonic TV that uses the same encrypted remote control protocols.) :-(

Very sad....

FX750 over here with the same issue as reported above.

I think it’s awesome that you’re putting the effort in to make this happen. Thanks so much! I sure wish I could use it. However, I think it’s going to need the ability to pair with the TV if it’s going to work the same way as the Panasonic smartphone apps.

Interestingly, however, I know it’s possible to execute commands without the pairing / encryption as I was able to control my TV using the simple node.js module here: https://www.npmjs.com/package/viera.js

It just doesn’t integrate with Homebridge as-is. I was hoping to make a Homebridge wrapper for it; but I failed and don’t have much free time to spend on it....

Hi guys. Thanks for your breakdown of the issue here. I'm not entirely sure how to go about resolving this since I don't have a newer TV but I guess if you still have that pcap file I can take a look and understand how the newer models are communicating.

Hello, it seems someone managed to reverse the device association Link, I hope this could be usefull.

Best regards

AntonioMeireles commented 4 years ago

hi folks!

FWIW - i recently got a GX830 (2019 model) which didn't work out of the box due to the lack of encryption support. So, at the lack of a better options, i implemented it :-) https://github.com/AntonioMeireles/homebridge-vieramatic / https://www.npmjs.com/package/homebridge-vieramatic.

it mostly works already (it's a work in progress) and i just made it public - feedback is welcome!

A great weekend for all!

@AntonioMeireles nice work, I've got it working on a FZ952B. I can turn it on and off and change the volume all by Siri, but what commands do i use to change inputs with Siri?
