Would the Google Nest Battery Doorbell be compatible with my Siemens Door Chime JSJS-303 (DCW5), which operates at 8V and 1Amp?
The British General Fortress 8-24V AC 8VA Bell Transformer Module can provide either 12V or 24V. Would it be better to power the Nest Doorbell with 12V or 24V?
Would a chime connector also be required for this setup?
There is approximately a 5-second delay between pressing the doorbell button and receiving a notification on my phone, often resulting in couriers leaving before I am alerted. Is there any way to reduce this delay? Please note that my internet speed and mobile network connectivity are excellent.

Hi Jim789,
Thank you for taking the time to reach out to us.
I'll be glad to answer your questions about the compatibility of the Nest Doorbell (battery) with your Siemens chime, the recommended Voltage and the notification delay.
The Google Nest Doorbell (battery) is designed to be compatible with wired doorbell systems operating between 8V and 24V AC. Your Siemens Door Chime JSJS-303 (DCW5) operates at 8V, which falls within this range. Therefore, in terms of voltage, it should be compatible. To learn more, please refer to this useful Google Help Center article: Check Nest Doorbell compatibility.
To provide you with more precise assistance, please post a picture of your Siemens Door Chime JSJS-303 (DCW5) wiring.
The Nest Doorbell (battery) requires 8 to 24 V AC with a power rating of 10 to 40 VA. Since your transformer can provide either 12V or 24V, both voltages are within the Nest Doorbell's requirements. Using 12V or 24V should both work, but generally, a higher voltage within the compatible range (like 24V) can sometimes provide a more stable power supply, ensuring consistent charging for your doorbell's battery. For more information, please visit our Google Store website and review the Nest Doorbell Installation and Tech Specs.
For the Google Nest Doorbell (battery), a chime connector is generally not required for wired installations. The battery version has internal circuitry that manages trickle charging without needing a chime connector. However, if you experience issues with your mechanical chime buzzing or not ringing correctly after installation, there have been some rare cases where a chime connector resolved the issue, though it's not typically included or required for the battery model.
I look forward to helping you get the most out of your Google Nest Doorbell!
Best regards,
Virna

Thank you, this is extremely helpful!
The primary question now is: can I power the doorbell using 24V and the chime with 8V, considering that my British General Fortress 8-24V AC 8VA Bell Transformer Module is capable of providing 8V, 12V, and 24V? Additionally, how would the wiring need to be configured in this scenario?
