I bought a transformer 220v DC to 5V AC and connected my old bell. Now I'm waiting for the noise suppression kit from Netatmo because it always vibrates (without ringing) despite the gong module. Unfortunately, I haven't received the part yet.

I too set up a home pod as a doorbell, it's simpler, I plugged Netatmo directly into the power with its transformer and then activated it. Beware that the doorbell does not work with the 5 ghz Wi-Fi network

Hi, unfortunately I don't know. I have configured the Apple iPOD Mini as a doorbell via Homekit.
