[F750] Boost preset sets fan to 0%

[jonkristian]

Selecting boost preset results in my ventilation being set to 0%. Same happens also via my automation which used to work fine.

service: fan.set_preset_mode

  entity_id: fan.nibe_83039_ventilation
data:
  preset_mode: boost

Hi jonkristian

Have this settings in Servicemenu: Boost is working

I have the same problem. Previously worked fine.

@msandvold I see that you have speed 1 as the highest and four as the lowest, which is interesting. according to https://api.nibeuplink.com/docs/v1/Parameters the ventilation_boost does this:

Start a ventilation boost, i.e. ventilation speed 4, lasting the system specific return time hours.

i.e. not the highest speed, but the highest numbered setting. which would set your ventilation to 25%, not 100% if you are correct, that means that the nibe doc is wrong (quite possible), and it is setting speed 1. I guess that a reasonable test would be to set speed 1 to 0, speed 4 to 40 and then see what boos results in :-)

@jonkristian what is the order of your ventilation speeds and have you perhaps done a firmware upgrade on your f750 between working and not working?

I just tested on my F370 (not 730), I have speed 4 set to 100%, and speed 1 to 25%, normal is 52%. when I apply the boost, the web page at nibeuplink.com shows 100, as does the fan speed in home assistant.

[msandvold]

@sunqan57 - I have adjusted these values in the sevice menu of my F750. 0 seems to be "normal" and 1 is boost (100%) for my setup. Ran a test to confirm.

[sunqan57]

@msandvold interesting, that means that the info in the api doc is outdated (or at least incorrect) What is the fan speed according to Home Assistant?

[msandvold]

@sunqan57 Home assistant display correct value, same as my F750. I don"t remember, but I think I had to rearrange the value "physically" in the F750 to get boost 100%, from HA. Default the value was arranged from normal, Then "Low to high". Have You tried to rearrange these values?

[sunqan57]

@msandvold no I haven't (I have a F370 which is different from the F7xx heat pumps) and I don't have any problems.

But when you say that you had to rearrange the values in the f750 to get the boost to work - I am guessing that there is a bug in the nibe uplink api itself and not in hass_nibe. It also means that @jonkristian and @sami-one shoud try to change the fan speed settings so that 1 is 100% and 4 is 25% (like you have).

there is one firmware change in v9086R6 that might be related: "Updated features regarding ventilation adjustment", but 9086R9 makes me think that anything can happen when you upgrade the firmware.

[msandvold]

@sunqan57 I have not checked the details, but its working for me, so if it's not broken...

Regarding SW, Iam running 9086R10, I have not updated to latest that seems to be 9086R12 .

[sunqan57]

@msandvold i don't want you to change anything. If it works when the order of the fan speed values are changed to what you have then that is what the two persons with the problem have to do as well. It apparently has nothing to do with hass_nibe.

[msandvold]

@sunqan57 Agree 👍

[jonkristian]

Sorry for the late reply.

@sunqan57 @msandvold I can confirm my speed settings were "wrong" (not like yours), I've done some firmware upgrades throughout the years but not sure if that was the cause. The boost is now working :)

I've adjusted them like yours, but could you please tell me what your settings on "Tilluft" is, since they aren't matching, and I don't really know if they should match or not.
