Hi Kiwi friends!

Does anyone have recommendations for a wireless, battery-powered smart button available in NZ (or that ships to NZ)? I'd like to use it with Home Assistant to act as a doorbell.

I can see things like this online, but the "easy to use, free app!" is off-putting... I'm after a button that has minimal capability to spy on me, and that can be integrated with HA.

Any suggestions welcome - or if anyone has any better ideas on an alternative option, go for it! We can't get mains power or PoE where I want to put the doorbell.
