 This simplifies the integration by creating the sensors for the various Itho Daalderop devices: Heatpump WPU 5G, HRU-350 and related devices, CVE boxes, Autotemp units for floor heating. 
 For best user experience it should be used with the auto-discovery for the CVE / non-CVE devices in the add-on.

 ### What works / should work
 1. Create Heatpump WPU sensors
 2. Create NONCVE / HRU Fan sensors
 3. Create CVE fan sensors
 4. Create up to two Remotes for monitoring CO2 levels
 5. Create Auto temp sensors
