How to use local ozw_config of z-wave device (HVAC adapter from Systemair)

Thanks @Dennis87, interesting that you link to a case involving the Eurotronic Spirit device. I found the solution to the problem I had in the OpenZwave forum on github about the same Eurotronic device: Thermostat set point fix

My solution was to install Hassbian instead of Hassio. Then I compiled the python-openzawe library with the Open-Zwave Dev branch and installed that instead of the official release. Then I had to make a new device xml and put it into the python-library folder on hassbian. The xml file had to specify the following:

<CommandClass id="67" base="0" typeInterpretation="A" />

Then it works. So until the pull request with the new command class Thermostatsetpoint V3 is merged with the master branch in open-zwave, it will not be possible to run Hassio. The fix is scheduled for the 1.6 release, the official version is still 1.4 I think. So I will have to stick with an unstable development branch for a while…
