ah thats not the proxy, for this you still need 1985 to be open… ?
yes, using port 1985
But I still have issues with the ISAP request on hangup button.
Not sure how that needs to be configured correctly…
Getting message:
“Die Aktion text/set_value konnte nicht ausgeführt werden. required key not provided @ data[‘value’]”
Guys, updated my advanced card tutorual using the proxy! much easier, no https needed anymore for go2rtc!! No open ports needed, no nginx 
Hi, does this extension works with EZVIZ CP7 Doorbell/Camera ?
You can try…
Hello,
I have a Hikvision Dormell DS-KV8113-WME1(C) (V3.7.0 build 250929). I have two issues:
- I get always an error “[CHikProtocol::DoRealCommonRecvInFollow] 4.fatal head-packed data error” and the service needs to reconnect.
- I get always an info “mqtt:update_door_entities:340 - Door 1 unlocked by 4849485755495554505700 , updating sensor and device trigger” but nobody opens the door?
Can me anyone tell me what the problem is? Below is my protocol. I marked three lines with ==>
Thank you Ludger

those door unlock events are old events, first time starting the addon , its downloading the complete backlog, so its quuite busy …
For the ones interested to try out the beta addon, i have added an image entity , you can take a snapshot , also on incoming ring event, it should create a snapshot automaticly, its also stored on the /media drive…
Hello,
Great project, thank you very much.
I’ve come quite a long way, but now I’ve been stuck on a problem for many hours: I can’t communicate with the outdoor station in the sense of two-way communication. No microphone is displayed in the camera card. With the help of AI, I’ve already tried “everything possible” without success.
Video stream is running (prepared on a Raspberry Pi by Frigate NVR with go2RTC and WebRTC). The camera is stored there as follows:
go2rtc:
streams:
Doorbell:
- rtsp://admin:[email protected]:554/h264/ch1/main/av_stream
- isapi://admin:[email protected]:80/
In Home Assistant (OS on Proxmox, other computer on the same network), the HIKvivion integration is running (the MQRTT entities appear to be all set up), I can also cancel/stop a call and open the door (relay) and hear the sound from the outdoor station, but I can’t get it to work with the microphone.
The Frigate, WebRTC, and go2RTC integrations are also running.
The devices are:
Outdoor station:
DS-KD8003Y-IME2/NS#EU
Firmware_V3.7.1_250819 (latest)
Indoor:
2x DS-KH6320Y-WTE2 (V2.2.96 build 241111)
How can I get the 2-way audio to work? Under 192.168.178. IP-HIKvison:1984 > on the left it says “Video+audio” (2-way audio is not checked). In Frigate, the stream info also says “Two-way communication is not possible for this stream.”
I think it’s a problem with http/https (I don’t really know much about that).The AI said something like that and suggested I try “flag” (“Insecure origins treated as secure”) to get around the problem, i.e., activate the IP of HP and webRTC-stream of HIK-visoin as secure.
Do I need to adjust any settings in the HIK UI? The AI suggested various options, but I can’t find them.
Can anyone help me?
Best regards,
Florian
There is guide on my GitHub page to use it with the advanced card
Hello,
I missed that! Sorry. Yes, that’s how it works.
Thank you very much!

Hello Fabio
I use a DS-KV8213-WME1(B) doorstation.
When i press the shnapshot button, the activity says the snapshot is taken, but there is no file in /media folder of HA.
Is there any advanced configuration necessary?
Best regards
Can you look at the addon log? Was it succesfull? Do you see it on the image entity?
This ist the printout of the addon log:
2026-01-27 18:23:13.558 | INFO | mqtt_input:_take_snapshot_callback:436 - Received take snapshot command, doorbell: Videotürklingel
Nothing more then that? What beta version are you running? Can you try to enable debug mode in the system options and try again? Can you post it on GitHub instead?
I don’t use a beta version. I use Version3.0.27.
can you try stop addon, and install 3.0.0-beta.116
you can just copy over the config, and start the beta
lots of things changed in the code
test again with also DEBUG enabled
