@Piwtorak,
The converters (XSLT) will move SQRemote AV-codes to the corresponding AV-codes in Vera/MiOS.
MiOS doesn't have any API exposure for AirConditioner codes, so these codes will remain (unchanged) in the target D_ and I_ files, but will all have a ServiceId of "*Placeholder*"
This would include any learned codes since they don't map to AV-codes in MiOS. You could hand map these in the file over to the AV-codes for "up, down" (etc)
Having said that, any learn'ed codes need to work first between the SQRemote and SQBlaster. If you've learned codes and they're not working there, then they won't "come to life" under the SQBlaster plugin either (since I simply replay the code that you've previously learned)
In talking with Matt some time back, there was effort put into making aircond units work, although I don't have the list of what ones were specifically done, or where that effort went.
