Model: Tapo D235  
Hardware Version: V1
Firmware Version: 1.1.14

I've bought the Tapo D235 for the purpose of having a doorbell that I can use the camera feed as a cctv camera and store the recordings on a NAS. After reading that with the firmware update ONVIF/RTSP is now supported (v1.1.14 upwards) - I bought it.

 

However, ONVIF/RTSP only functions with the always-on mode (which I knew), which requires power (which I have). I can get the doorbell to be powered by the transformer built in to my chime, but cannot enable the always-on mode. As I understand it, this requires the use of the jumper cable (supplied). When I use the jumper cable to connect/short the 2 connections where the doorbell wire attach, the chime/solenoid will constantly engage and buzz, and then the Tapo app will complain it isn't wired correctly.

 

Can anyone suggest how to get this to work please?

(The transformer is meant to provide 8V AC 1Amp according to the documentation, but I get 16V AC across pins 0 and 2).

Just google this model and find some information on Byron's website, this model's built-in transformer can only provide output of 8V 1A AC, it does not support doorbells that require higher voltage.

You can try using another qualified transformer to install with the D235, check if similar issue still exists.

Hi, thanks for the reply. I'll be honest, I'm utterly confused with this set up, but because I actually got it working.

 

You are right, the transformer is rated as 8V AC 1A in the documentation as I noted, but I was getting 16V AC when I measured. The D235 is rated to accept 8-24v AC so the voltage isn't the problem but at 1A it will be below the 10VA minimum required. I hooked it up yesterday anyway, even though my testing the day before showed it wouldn't work as I wanted.

 

I don't know why, maybe I got the D235 in a weird state of settings during my testing, but when I hooked it up it worked fine. It is powered by the wires/transformer without the jumper installed and always-on mode is enabled with the ONVIF/RTSP stream connected to my Synology Surveilence Centre. There isn't any buzzing from the chime/solenoid, but as expected, when using the always-on mode I have to use the wifi chime instead to replace it.

 

A mystery to why it is working in all honesty. At least for the moment.

Tapo D235 operates within a voltage range of 8-24V AC. If your current measurements fall within this range, the device should function correctly. It is possible that an incorrect option was selected during your previous configuration process so there was a error message. I recommend monitoring the device's behavior closely to ensure it's working properly.

I think I have the same chime..

 

Had a Ring Doorbell4 installed for the past 3 years (hardwired from existing doorbell) with no issues...just sick of paying £50 a year subscription...

 

Installed the Taps D235 and my chime just won't stop buzzing? The bypass cable stops the power going to d235, without it, it powers the d235 but makes a continuous buzz... Any solutions please?

@GusB  As mentioned here, the official specifications for this model clearly state that the transformer can only provide a maximum output of 8V 1A AC, and it doesn't support connecting doorbells that require higher voltage.

 

I'm not sure how @ritchie1 managed to wire it to get higher output power, you can check with him.

 

@ritchie1  @GusB However, for safety reasons, I strongly recommend that you contact the Byron's technical support to confirm the current transformer connection is correct and doesn't pose any safety risks.

The wiring is correct - pins 0 and 2 are for doorbell wire.

 

Don't use the jumper.

 

The hardwire mode should be recognised automatically. You might have to configure which type - using the chime or always-on (not using the analogue chime). I suspect you want to keep the old chime as a chime which is not how I'm using it.

 

Try connecting, then turning on power and see what gets recognised by the door bell.

 

I still might change mine - I believe there are power issues with the infrared turned up to maximum. I'm waiting for all other bugs to be fixed first so that I can narrow down what might be power related.
