Hi, looking for a new doorbell for home. Have a reasonably large house with two entrances, so would like a doorbell system with two transmitters, and at least two receivers, and haven't seen anything available at a reasonable price in NZ.

Found this on Aliexpress:

Would that combined with simple EU to NZ adapter:

... do the trick? The receiver voltage is AC 220V, 50Hz, I understand I shouldn't have any trouble with this in NZ? It would only be around $40 NZD all up.

Thank you

Yes it would work fine. You just need to be aware that running a device of a power adapter permanently is not recommended, and I'm pretty sure does actually break NZ electrical regulations.

The plug you show is a US plug, not EU. (It's normal nowadays for the same device to run off either 110V/220V). As such, you can twist the pins with pliers to fit into a NZ socket.

You could also search for doorbells with an "AU" plug... Ozzy plugs are the same as NZ.

Another option might be to look at the LinBell (KickStarter project). The doorbell is self-powered (no batteries, no wiring). https://www.kickstarter.com/projects/447699089/linbell-the-wireless-doorbell-requires-no-battery

You might want to try and establish what frequency the door bell operates on as well.

If you are talking about the power supply freq, for something such as a door bell with a wall wart, 50/60Hz won't matter.

On the other hand, checking the freq of the transmitter would be warranted.
