Honeywell RUD (4557a-rexuanz)

[mcattle]

Has anyone been able to get readings from a Honeywell RUD (4557a-rexuanz) two-way smart electricity meter?

Here's what I've been able to dig up on the communications chip:

I am also interested in whether anyone has done this successfully. Toronto Hydro has installed one of these on the unit I'm renting, and I would very much like to be able to track power usage at the meter without going to stick a camera or some similar sensor to it.

I would also like this.

I have a Neptune R900 water meter that I am able to read, but the 4556-REXUANZ power meter isn't showing up.

Also located in Ontario, East of Toronto.

I do see an occasional SCM+ message, but after 12+ hours of logging there's only 4 unique MeterID's. Also after 12+ hours of logging, I've only captured 2 SCM (non-plus) messages

If helpful to the author, I can capture some raw audio samples.
