Thanks for confirming the manual makes sense, Sipke 
Can you show the MQTT Explorer screen with the itho/ithostatus topic? Especially the speed-status and fan-speed_rpm (or something similar), like this:
Because it shouldn’t, but it could be possible they’re not named exactly the same with our NRG add-ons….
The point is, these names should match with the ones of the valueTemplates in the MQTT device:
When the names appear to be different at MQTT Explorer, you should adjust the ones in MQTT device topics to have it matching.
Does this make sense? Just ask when things are unclear.
