seg fault in meters.cc line 682 about wmbusmeters HOT 5 CLOSED

Thanks for the bug report! There was no support for parsing the libmbus secondary address. But I have now added support for this! Also the segfault has been translated into a warning if somehow a bad address would get to that part of wmbusmeters.

Please test again!

A fully specified libmbus secondary address is 16 hex digits, for example:
100002842941011B
this includes the id 10000284 and the manufacturer 2941 (translates to PII) and the version 01 and the type 1b.
wmbusmeters had support for the fully specified address:
10000284.M=PII.V=01.T=1b
where you can leave out M,V,T as you like.

But since libmbus is frequently used, I added support for their version of a fully specified address as well. :-)

As for the driver, I am working on a new text based driver system. As long as you get good data, the warning can be ignored. It is probably just another version of the meter but with a lot of similar values, perhaps all.
Please post a telegram here so that we can take a look.

Landis+Gyr rebadge some of their meters for other suppliers. e.g. The ista ultego 3 is exactly the same as the T230 even down to the ordering information.

Currently exploring the driver.xmq to save hacking around with the ultraheat.cc source - Any documentation available aside from the dvparser.h ?

Appears to be working, and exits gracefully with an invalid address.
