core: Samsung TV can't be added (Websocket error)

The problem

I’m trying to add my Samsung TV, using the Samsung TV integration from the integrations menu. Unfortunately it says the TV is not supported. It’s a 2017 model running Tizen (UE55MU7000). I had it running with the tizen custom integration, but removed it a while back. This made me wonder why it wouldn’t work with this integration.

When I turned on debug logging while adding the TV, I receive the following log: 2022-03-14 12:07:10 DEBUG (SyncWorker_3) [homeassistant.components.samsungtv] Try config: {'name': 'HomeAssistant', 'description': 'HomeAssistant', 'id': 'ha.component.samsung', 'host': 'xx.xx.xx.xx', 'method': 'legacy', 'port': None, 'timeout': 31} 2022-03-14 12:07:10 DEBUG (SyncWorker_3) [homeassistant.components.samsungtv] Failing config: {'name': 'HomeAssistant', 'description': 'HomeAssistant', 'id': 'ha.component.samsung', 'host': 'xx.xx.xx.xx', 'method': 'legacy', 'port': None, 'timeout': 31}, error: [Errno 111] Connection refused 2022-03-14 12:07:10 DEBUG (SyncWorker_2) [homeassistant.components.samsungtv] Try config: {'name': 'HomeAssistant', 'host': 'xx.xx.xx.xx', 'method': 'websocket', 'port': 8002, 'timeout': 31} 2022-03-14 12:07:10 DEBUG (SyncWorker_2) [homeassistant.components.samsungtv] Working but unsupported config: {'name': 'HomeAssistant', 'host': 'xx.xx.xx.xx', 'method': 'websocket', 'port': 8002, 'timeout': 31}, error: ('Invalid close opcode %r', 1005) 2022-03-14 12:07:10 DEBUG (SyncWorker_2) [homeassistant.components.samsungtv] Try config: {'name': 'HomeAssistant', 'host': 'xx.xx.xx.xx', 'method': 'websocket', 'port': 8001, 'timeout': 31} 2022-03-14 12:07:10 DEBUG (SyncWorker_2) [homeassistant.components.samsungtv] Working but unsupported config: {'name': 'HomeAssistant', 'host': 'xx.xx.xx.xx', 'method': 'websocket', 'port': 8001, 'timeout': 31}, error: ('Invalid close opcode %r', 1005)

It looks like the config is failing on the web socket. When I check the API with: http://xx.xx.xx.xx:8001/api/v2/

I’m returned the correct information of the TV: {"device":{"FrameTVSupport":"false","GamePadSupport":"true","ImeSyncedSupport":"true","OS":"Tizen","TokenAuthSupport":"true","VoiceSupport":"true","countryCode":"NL","description":"Samsung DTV RCR","developerIP":"0.0.0.0","developerMode":"0","duid":"xxxxxxxx","firmwareVersion":"Unknown","id":"uuid:xxxxxxx","ip":"xx.xx.xx.xx","model":"17_KANTM_UHD","modelName":"UE55MU7000","name":"[TV] Samsung TV","networkType":"none","resolution":"3840x2160","smartHubAgreement":"true","type":"Samsung SmartTV","udn":"uuid:xxxxxx","wifiMac":"none"},"id":"uuid:xxxxxxxx","isSupport":"{\"DMP_DRM_PLAYREADY\":\"false\",\"DMP_DRM_WIDEVINE\":\"false\",\"DMP_available\":\"true\",\"EDEN_available\":\"true\",\"FrameTVSupport\":\"false\",\"ImeSyncedSupport\":\"true\",\"TokenAuthSupport\":\"true\",\"remote_available\":\"true\",\"remote_fourDirections\":\"true\",\"remote_touchPad\":\"true\",\"remote_voiceControl\":\"true\"}\n","name":"[TV] Samsung TV","remote":"1.0","type":"Samsung SmartTV","uri":"http://xx.xx.xx.xx:8001/api/v2/","version":"2.0.25"}
