Can't connect to a breaker energy measurement device

[Moncader]

I'm trying to connect via b-route to a Toshiba HEM-EM35A-B2 unit.
It is WiSun-based and has a ID and Password along with a hard-coded IPV6 address written on it.

I also have a smart energy meter and can use this library just fine with that. However I can't seem to get it to discover this product.

The device says it's in network register mode (Which I would assume to be discoverable since the official documentation says to connect it to your home gateway when it's like that).

Debugging the raw serial line with data-serial event shows nothing happening on the line besides the EVENT 22 going on forever.

Have you ever tried working with a unit like this before?
If it not, do you know of a way to try to debug this device further?

According to the official web site, Toshiba HEM-EM35A-B2 seems to support Wi-SUN HAN, not B-Route.

Unfortunately, this module does not support Wi-SUN HAN, and is not planned to support it for now.
