Zigbee (or other) water clock/water meter for indoor use (Germany 3/8")

Hardware

Hi there,

I’m looking for a water meter with ZigBee or other connectivity. Was not able to find a decent solution for a good price. Living in Germany, our standard water pipe threads are 3/8" iirc

Bluetooth or Wi-Fi would also be acceptable, but using it with z2m is preferred.

Thanks

Lars
