Nest Hello doorbell (battery) not working on auxiliary power

mickeyr61 — Fri, 10 Dec 2021 14:52:23 GMT

Last week I have received the Nest Hello Doorbell (battery) powered. I removed the old button (bell) and installed the device smoothly. Because there are some extra options when you power it using the bell transformator, I later on installed the Doorbell on the auxiliary power. (8W transformator/ 1A). This worked fine, when I checked the settings the doorbell was externaly powered. So far so good. But after a couple of days, the doorbell was switching back to batterypower. The percentage battery dropped down to 61%. Contacted google support, the advice was to reinstall the application on Google Home and then choose external power (instead of battery power). That worked, for a couple of hours unfortunaltely. The doorbell is again back to battery power.

I want to use the external power because it also is connected to a mechanical gong. This makes a much more louder sound than the Google mini. When a person presses the doorbell I mostly miss it because the sound on the mini is too soft. I can turn it louder, but when my family plays music they turn the volume down, and the bell sound is very weak. I also find no settings in the home application to make a louder volume on the mini when somebody rings the bell.

The reinstall the application every couple of hours is a workaround, but not a good one 🙂 Maybe the auxilairy power has nog enough power (1A / 8V)? Or maybe the cold temperatuur outside (2 degrees Celsius)?

Before I forget I checked all the cables with a universal voltage device and they are ok.

Got exact the same thing. Did you find anything?

What I found out at the moment is this: The Google Nest Doorbell (battery powered) can be used with a 8V connection. The transformer I am using (which is a quite common one in Holland) gives 8V volts, however it supplies 8VA. The doorbell uses a little bit more than 1A, say 1,25A so you need a transformer which supplies about 10VA (or more). It is possible to replace the transformer with a 12V or higher one, but then you also have to replace the ringer (which now uses 8V). Sending a higher voltage to the doorbell could ruin it. This is my theory, I didn't have time yet to prove it. Proving it, means bying a 10VA or more transformator which suits in the same socket as the previous one. To be continued....

Please see my remarks above. Is it correct that 8VA is not enough to power the Google Nest Hello Doorbell (battery powered)?

I have a TS8/8 SWH transformer. With 8V and 1 A. So is this the actual problem? What transformer do I need to make it work? It's still kinda strange it worked for like 4 days, and now it barely works.

@Spelvout

Nest Doorbell (battery) can be powered with wires delivering 8 - 24 V AC, and at least 10 VA, 50/60Hz, worldwide. I will state now, I am not an expert at all when it comes to wiring and electrical work. Have you tried to test using a multimeter yet? If so, what are the readings?

Best regards,

Brad.
