Hi @pravussum,
I’ve been monitoring “Extract Fan Step” a few times since yesterday, so here’s the results I have at this time. First, when setting the step manually using “Manual Fan Speed” as a test to see if the values will match (which they should):
Manual Fan Speed -> Extract Fan Step
- 10% -> 11%
- 20% -> 23%
- 30% -> 34%
- 40% -> 45%
- 50% -> 56%
- 60% -> 68%
- 70% -> 79%
- 80% -> 90%
- 90% -> 100%
- 100% -> 100%
A little bit strange, but especially step 9 and 10. I can clearly deduct step from current power consumption in Watt. Step 8 will use ~71 W, step 9 ~91 W and step 10 also ~91 W. When changing between step 9 and 10 from openHAB in manual mode, I can see the steps change accordingly on my Link CC display, but power consumption doesn’t change. And also, “Extract Fan Step” doesn’t change - but is 100% for both steps. So somehow it doesn’t seem to represent the steps exactly, but perhaps something related, although slightly different?
Just note: I have been using Link CC to see actual step as I have been having issues connecting from PC-Tool and openHAB binding at the same time. It seems to get updated quite quickly when changing manual steps from an openHAB sitemap, so I believe results are pretty accurate/consistent.
When mode is “demand”, more “Extract Fan Steps” come into play. For example, I’ve observed:
Extract Fan Step -> Step
- 70 -> 6
- 71 -> 6
- 72 -> 7
- 73 -> 7
- 75 -> 7
- 77 -> 7
- 79 -> 7
- 88 -> 8
A bit strange how extract fan steps relate to actual steps between 6 and 7.
From the linked document, is “FanStep” and “Resultant FanStep” currently being mapped to any channels? Could also be candidates for this value I’m seeking? Don’t know if “FanStep SP” (as being writable) is mapped to the manual fan speed - in this case one of these two seems likely.
Best regards,
