Water meter in HA (NZ)

1

Hi,

How do I integrate this water meter in HA? I have no starting point. This is in New Zealand.

Thanks.

Edit: This is a smart meter using the LwM2M protocol. More on this here - https://www.edmi-meters.com/wordpress/wp-content/uploads/2023/02/WP20-Factsheet-English.pdf

After doing a bit more research on this, looks like it uses the LwM2M protocol. Would there be an ESP32 route for this?

Lwm2m is the protocol, but you first have to establish communication with the device.
It seems to use NB-IoT, if enabled.

Just googling around, here. First time I hear about either.

Maybe useful:

Too bad I’m not in your shoes. Would have been a fun project :slight_smile:

Thanks. This gives me a direction to look further into.
