Nest Doorbell Battery with Byron 776 Chime

I have wired my new Nest Doorbell (Battery) to my home’s existing Deta c3504 mains powered chime with integrated transformer (output 10V AC). The doorbell charges fine, but the chime does not sound and the doorbell does not recognise that it is wired - it states that it is running on battery but the level stays at 100%.

I know that the first generation Ring Doorbell (also a battery powered device) worked with the Byron 776 mains chime with integrated transformer (outputs 8V AC) and was wondering if anyone here had experience of successfully wiring the Nest Doorbell (Battery) with this chime so that it both charges the doorbell and sounds the chime when the doorbell is pressed?

Thanks in advance for your help.

I have just wired-up the Byron 776 with integrated 8V AC transformer and can confirm that the Nest Doorbell (Battery) recognises that it is wired-in and also chimes the doorbell when pressed.

Hmmmm,  mine said battery but the moment I connected it to the doorbell wires it changed (in the app) to show it was NOT using the battery.  So I'm not sure what is going on with yours.  I see the specs say "Doorbell power: Rechargeable battery (included), or existing doorbell wires (8–24 VAC, 10 VA, 50/60Hz transformer).".  It does not matter which of the 2 wires you connect because it is AC power.  Can you get out a voltmeter and set it to AC and see what is says for the voltage coming out of those wires just to confirm?

Thanks mdr2 - mine says battery, but is staying at 99-100% charge. I suspect it is drawing power from the chime but that the chime itself isn’t compatible as pressing the button doesn’t cause it to ring.

Older posts for the original Ring doorbell demonstrate that the Byron 776 chime works with that battery operated device. At £12 on a major online retailer named after a river, it’s worth a pop. Are you using the Byron chime?

I do not have that doorbell but I just confirmed from the specs that it looks like it should work.   If you are interested in doing a bit more trouble shooting you might try and find another power source just to test it.  Look around the house and see if you have any AC power adapters that say they have an output of about 12-16VAC... but make sure it says AC.  You do not want to send DC into this doorbell.  Once connected to the 2 screws on the back of the camera it should see the AC power source and it should work.   If you are not comfortable with a bit of DIY electronics then you may not want to attempt this.

Hi @brisgasdoc is your 776 keeping it charged please? I have just "upgraded" a 6v chime to this one at a huge cost of £13 on Amazon 🙂 and it (for the first time) was saying "plugged in" rather than a bettery percentage. I did connect it at only 25% though, and now it is showing 20% after 2 hours. To be fair I had video on Max quailty and clips at 30 seconds, and I have a busy household (plus I have been live viewing for bit) How is yours holding up please?

One thing about the 776, and the device in general, is that my doorbell did not operate the chime at first, after I swapped out the low powered 6v one. After much head scratching I worked out that the doorbell was automatically assuming battery power, despite being connected to the newer transformer. this was due to being only only at 2% and me disconnecting it forcing it into this mode. After a quick burst of charge to get it to 25% it recognised the new power source and stated "plugged in"

Hi there,

 

Sorry for my late response. Thank you for all of your patience while waiting for a reply. I just wanted to make sure that your issue is addressed. I can definitely understand how frustrating your situation must be. I would love to help you find a solution to this issue. 

  • Do you still need help with this issue?

  • What troubleshooting steps have you done thus far? 

  • Have you tried to restart your device if you haven’t already?

  • If the restart didn’t work, have you tried to do a Factory Reset? This would be a last resort option, but would clear out issues and the device would essentially be ‘brand new’

Please let me know if you need further assistance. 

Best Regards,

Brad.

Sorry, only just catching up with your posts out of order. Given the intermittent sounding of your Byron chime, I wonder if there is a problem with the wiring between your doorbell and the chime? We had a power cut at home the other week and when it came back up I noticed the doorbell still thought it was on battery until I power-cycled the chime a couple of times. If there is high impedance in your wires between the chime and the doorbell (owing to degradation or similar) it might be that it is flipping into battery rather than accept an intermittent power supply?

Why not try wiring your doorbell into the chime inside (using a short length of stripped down Cat 5 cabling) and see if it holds its charge?

Alternatively, I started my doorbell on its wired journey with a 99% charge, so maybe it just needs to be higher if it is trickle charging from a low voltage power supply?

All the above comes with the extreme caveat that I am certainly no electrical engineer 😂

An update….. ok so after a week on the 776 as a power source my doorbell is down to 14% and not showing the “plugged in” icon when I check the battery - BUT I did set it max quality video and upped the recording time and sensitivity. I live on a really busy street and I think the camera wakes to everything, even if it is not in a zone - I can imagine it has to in order to apply the zone rule for notifications and recordings. I’m going to try and reduce the settings and see how I get on. I’m also going to look for a more angled mount so I pick up less of the street - one on Amazon US website but not in UK at the moment 

The first time I connected my Nest Doorbell (Battery) to the 776 it still showed the battery indicator. I had to reset the device and set it up from scratch again, and when I flipped the power switch to the Byron chime it detected it was wired and the battery indicator disappeared from the app. I have a similarly sensitive setup, although not at the highest quality and there are no problems holding charge (indeed there is no charge indicator).

My bet is that your doorbell hasn’t detected it is connected to a power supply for some reason. Hope this helps.
