For quite some time, I’ve been holding back a post introducing my Miele@home Android project. So in the wrong order, here’s an attempt to get in touch with some fellow Miele@home geeks: Sharing my findings about the new XGW 3000 firmware upgrade, which was released last week.

My findings are only about the Homebus protocol and multicast packets, since the new JSON-RPC protocol isn’t for public consumption (or so it seems). So here we go – changes since version 2.0.0:

• Element ‘type’ in http://<gateway>/homebus/ seems to be working again (e.g. <type>WMV960</type>). I’ve never seen this work since the original firmware of my gateway (1.1.0).
• Prior to 2.0.3, multicast packets would refer to a ZigBee MAC address (at least when communicating with XKM 3000 Z modules): “id=hdm:ZigBee:<MAC>”. This is now changed to device UID.
• For some devices numeric values are now included in the http://<gateway>/homebus/device XML:

  <key name="State" value="Running" type="state" raw="5"/>
  <key name="Program" value="Cottons" type="program" raw="1"/>
  <key name="Phase" value="Rinses" type="phase" raw="5"/>
  

  This is true for my WMV 960, but not my TKR 350 WP or H 5581 BP. They all have the XKM 3000 Z module, but the WMV has firmware version 1.16, while the other two are version 1.02 (does anyone know if these modules are firmware-upgradeable and/or where to find a changelog?).

Bugs still present:

• Language parameter not respected for http://<gateway>/homebus/device?language=en. Gateway language is always used.
• Bizarre values for key “Start Time”. Will update the post on this later.

That’s it for now. I’ll return later with more information about my project as well as rants about the Homebus protocol and Miele’s secrecy and lack of support.
