You can wait for Matter support (but often Aqara Matter only works in combination with an Aqara hubs)
Or maybe dev Martin feels like to add it to the Homekit Controller app, which he initially built to support Aqara FP2 presence sensor, which also uses Wifi.
You could request for G4 doorbell support with Martin here; But I’ve read there’s no API for the G4, chances are not high;
He probably needs a unit from one of you, or buy one as a group?
Also, it’s request at the request-a-brand site already,
but I’m afraid it’s another bottomless idea box it can take months or years, when I look at the tons of requests.
