My Google nest doorbell (battery) is connected wired and the Google Home app also says it is wired. However, the battery is still draining and seemingly not charging. It is now down to 68% in 2 days while it says it is plugged in in the Home app.
Hello ElV... It sounds like the power on your transformer might be too low to power the doorbell. Can you find the transformer that powers your doorbell and look to see the rating on it? Here is what to look for: There are 2 important numbers. The VAC should be anywhere in the range of 8–24 VAC (which it most likely is or your nest camera would not be working at all) . But the next important number is the "VA" rating. For this doorbell it must be 10VA or higher. If your transformer is lower than that you will probably need to replace it with a strong one. The good news is they are inexpensive. You can buy them at your local home supply store or Amazon. You will definitely want to match the VAC number that you currently have just just get one that is also rated for 10VA or higher. Hope this help.
Hmmmm, yes, I'm pretty sure you have that correct as "VA" means (volts x amps). I'm pretty sure that is why your Camera is showing the falling battery level. So here is what else this mean, If we do the math backwards and we know the Doorbell is asking for 10VA, then (10VA / 8 volts = 1.25 Amps). So you would want to find a new 8V transformer (since that is what your old doorbell wants for voltage) and at least 1.25 AMP (or slightly more).
Looking on Amazon I see many transformers that offer oth 8v and 16v depending on which screw terminals are used.
Love to hear how this turns out.
Could you maybe share a link? What I see mostly is ac/dc power supplies and what the doorbell seems to need is AC-AC.
The power supplies that specifically mention the old model Hello doorbell have 18V at 500mA, which would give 9AV,which is just a bit too little for the new nest doorbell model.
Hi, I have the same issue, my transformer is 8v 1.0A. Doorbell is showing 20% charge and doesn't seem to be increasing. What would be the recommended transformer rating for the doorbell to work and charge effectivley?
You basically need something that says 10 VA or greater.
Yours has 8V * 1.0A = 8VA
I ordered a new one from Amazon that gives either 12 VA or 24 VA ( a VEMER VN318200).
It should arrive today and I'll see if I can get it to work.
Hi there, folks.
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 am terribly sorry to hear that your Nest Hello Battery doorbell is not charging all the way, and draining. Definitely some form of power issue from the sound of it. Thank you all for helping each other out! I think it may help if you do a multimeter test reading, if you haven't already. If you continue to run into these issues, please reach back out.
The battery should last you an average of 3-4 weeks on a single charge. You may want to adjust your settings as that could lower the amount alerts and notifications coming through. I have see that work quite well for others who are trying to save their battery life. Please let me know if you need anything further.
Just wanted to jump in here to check to make sure that you saw our response. Please let us know if you have any other questions or concerns as I will be locking this in 24 hours.
Have a great day.
It looks like we haven't heard back from the OP so I'm going to go ahead and lock the thread. If you have any further questions or concerns, feel free to create a new thread.
Have a great day,
Yeah, well my brand new transformer is 16v 30VA and mine too is ‘potentially’ draining as well. If i turn off the breaker and force the doorbell to battery mode, it showed 68%. Now is it draining, maintaining, designed to fluctuate….not sure yet? One would think it would always be topped off at 100%, but maybe not to maintain optimum battery life? Maybe it cycles from 50% to 100% and back again???
Also, I had a 24v installed to begin with, but unfortunately, it was over producing at 26v and it was causing problems with my digital chime.(it would only provide a .5sec chime regardless of how many seconds I selected; it would click per second and provide the brief chime at the end) Per tech support, the over voltage more than likely was the issue. After replacing with a 16v 30va my chime issue was resolved and door bell chime rings normally (3sec chime). BUT, it does occasionally randomly click which can only be heard if the room is completely silent. Tech support is aware, but has not provided any further suggestions.
