I'm looking for a doorbell for my Dahua NVR setup.Thanks - I was just reading a post you made on the Yoosee support site.
IPCTestTool - or at least the English-y version V01.00.00.62 - does not seem to be able find my device. Onvif test tool sometimes discovers it. Onvif Device Manager reliably finds it, can query 'capabilities' successfully, but anything else fails. CMSclient keeps throwing Password Errors, but won't allow me to proceed with a blank password.
I was getting frustrated running WireShark - the device just keeps closing TCP connections.... but RTSP streaming (main stream, anyway) works fine to my Dahua NVR.
It's so close..... but so far.
Hello guys, it is possible to connect this doorbell to a mechanical chime. You need a Power Regulator for this. See links. DS6855 | module voor aansluiten bestaande gong op de DS6840/6841 - (in Dutch)I also checked for a drop to zero and got the same results. Was getting ready to respond when I saw your reply. Not to confuse the issue, but as mentioned in one of my previous posts... since YouSee is the app creator for this doorbell I believe the YouSee SD-M5 is actually a renamed KW-05 as made by KONX Electronics LLC but marketed my YouSee.
In any event, per KNOX LLC, the KW-05 works "with" your existing mechanical doorbell, however I have been unable to find any reference or documentation as how to acheive this.
Also... unlike advertisement for the SD-M5 ... some ad for the KNOX KW05 show a "Power Regulator" as an optional accessory. I can't help but wonder "if" it's a requirement for connecting a mechanical bell. In the meantime... I sent an email to KNOX LLC asking for clarification on how to accomplish the mecanical doorbell connection.

From the connections, it looks like it's a relay more than a fancy name "power regulator", it doesn't seem there is power regulating here. Correct me if I'm wrong.

No, it is not a Power Regular. It is likely to be called so, so that the price can increase. It looks like a 443MHz receiver in combination with a relay. You can indeed buy this on AliExpress for a few Euros. You just have to be careful that the contact is not constantly closed when the relay is triggered. The contact must therefore only be closed for a short period, otherwise the chime will continue to sound continuously (Output way: Momentary). See link on Aliexpress:From the connections, it looks like it's a relay more than a fancy name "power regulator", it doesn't seem there is power regulating here. Correct me if I'm wrong.
The relay NO/COM connection acts as original door bell mechanical button. NO is normally open. When there is trigger, NO becomes closed, same as press the button to close the loop of the door bell. From the browser's translation, it said "From the doorbell, a wireless signal goes to this module when the doorbell button is pressed outside."
So, my guess is it's basically a 433Mhz RF single relay. It's powered by the Vcc/Gnd, and paired with the Yoosee button (in fact, can be paired with multiple buttons)
For a RF relay, it's way overpriced at 39 Euro. It's only a few US dollars at aliexpress, the one I got for adding more cheap remote to my garage door.

There are many choices depends on voltage and with remote or not, might be able to find one using the power from the transformer of your chime so not requiring another transformer to power the relay.

I haven't used an RTL SDR before, but just ordered one for tomorrow delivery. Can you give me some tips of how to use it in relation this this please?
Since you are using BL, you can grab it from BL instead, for example if your BL server is 192.168.10.140 and you are using the default port 81 for ui3, with a cam named in BL as FrontDoor, try the following, under your camera section in your configuration.yaml:
camera:
- platform: mjpeg
name: FrontDoor
mjpeg_url: http://192.168.10.140:81/mjpg/FrontDoor/video.m3u8
still_image_url: http://192.168.10.140:81/image/FrontDoor
Thought only one sec pulse short time! maybe should have feature setting long pulse 8 sec door bell, have done?
I believe mechanical chime only needs a short pulse and that's how the door bell button work. You don't hold the button, you just press and release.
12-24V DC input POE Injector straight to doorbell only, separate POE Switch/NVR 48V wont through POE Injector to doorbell, looks like here picture, all be fine safe, Maybe POE Switch/NVR 802.3at/af won't work communicate data through doorbell standard ethernet, because Doorbell is Passive PoE only.
