This looks interesting :D Maybe it is possible, to get a signal from the relay (the big white component on front/top) - for those, who want to experiment with microcontroller-circuits ;) Im pressing my thumbs for you that the missing resistors are by design (not by mistake) and the chime will...

My experience was a little different, but I think, this depends on Chime + Transformer: Chime was not buzzing with powerkit, so I got the impression that its working. But the bell rang accidentally... I couldn't find a connection between current flow (IR mode active/inactive) and triggering the...

@Phontana: I guess you'll never get it to work with missing resistors. But i can understand that you want to fix it yourself, especially after 3 exchanged devices... You can try to solder the missing resistors yourself - Im not 100% sure, but I think, you have to look for 10 Ohm SMD Resitors...

+1 on this - lost one screw, too. And I'm to scary, to remove the remaining one and loosing this one too. Has someone any Details about the Screws or can measure it? Or do you know, if they are the same as on the Ring-Systems? Saw some of them on Amazon (B08MTDZSPN) (including M2 and M3.5...

Another small Update for those who care :D Unit is now installed and working great. For now its wired up to a mechanical chime, because I'm assembling the smart one. I designed a little circuit and want to share it with you; maybe it is useful for anyone out there - but be warned (!) I'm not an...

Well, I made a little circuit-sketch (wrong components, just for imagination): part 1 is the classical chime wiring (Lamp = Chime). The Push-Button (Switch) closes the whole circuit if pressed - the Bulb shines, ehm i mean, the chime rings :D part 2: the doorbell is more than just a...

OK, finally its working. Support answered really quick with standard answer (they described every single step the app force me to follow). Anyway, to describe my problem step by step, i tried it again and it just works. My guess is, they changed something in the backend or whitelisted the...

Again a little Status Update: At first, now i got 2 devices laying around - thanks to amazon i have some time to send back the faulty unit. I spend now over 2 hours to get the new Unit working - i tried it with the following options: EZVIZ App (the regular way) Problem: After configuring WiFi...

I tried it with: 12V, 1A AC (regular Din-Rail Transformer) 24V, 2A AC (Transformer for Surveilance Camera Systems) 8V-16V-24V, 1,5A AC (regular Din-Rail Transformer with 3 Connections for different voltages) Labatory Power Supply, tried with 12V and 24V DC @ max 5A (to avoid frying something I...

The only Diffence I saw (well, just on the surface, no Oscilloscope here) is a ~0.5 seconds rining on mode "mechanical" and 1s to 5s (if i rememer the range correctly) in mode "digital". I tried to monitor the current & voltage in hope of finding something suspicious like a peak, spike, etc...

Yes, I'm aware ot this. My Problem is, that after some time Phantom-Ringing occurs (Chime is ringing, but nobody pressed the button and there is no Notification in the App). BTW: I tried all modes, the App suggests: mechanical chime, digital chime and no chime; none of them works as expected.

Every Suggestion is a good one ;) Well, i am fed up - i give it a try and send the whole package back and try another one. If this unit will have the same problem, i will ask Ezviz for another powerkit (with all resistors). I tried 3 Power Supplies + 1 Labaratory Power Supply, 3 analog chimes, 1...

Just a small Status-Update: My Unit seems to be a strange one. I tested until yesterday with another chime - everything was working. I changed the Chime again to measure (as promised) the Specs of the Chimes, but suddenly they worked, too. So I changed at last to the relay (nothing else...

It's a coil/solenoid one. No further Description on it. It was installed together with an 12V AC Transformer in a House. It seems to be designed for AC btw. At the moment I'm testing with another Chime (coil/solenoid too, but with 2 Sounds). The coilwindings are thicker and its now working for...

Thanks for your quick reply. In Reference to your pictures from the power kit (New RCA HSDB2A 3MP Doorbell IP Camera), there are only 4 100Ohm Resistors missing (I think, the black parts on the backside with "100" print on were resistors), but somewhere in this thread i saw this already, seems...

Hey, maybe someone can help - i'm not able to get the ezviz running with a chime or relay. At first, i though the transformer is too weak or there were voltage spikes (or something other the powerkit can't handle); its a 12V / 1A AC Transformer. I tried a 24V 2A one, but also not working as...
