F750 Airflow sensors lack of units #111

Open pacco788 opened 11 months ago

pacco788 commented 11 months ago

Hi, I'm using the NIBE Integration in HomeAssistant. Was wondering why there are no units for the airflow sensors. Couldn't use it for automations and it didn't show a graph.

After a little research I found the problem. The airflow sensors in your F750 file have no units. Should be m3/h. Affects EB100-BS1 Air flow (40050), Airflow ref. (43124) and EB100-BS1 Air flow unfiltered (40051).

Would be nice if you could add it.

I see that 40050 and 40051 have different multiplication factor for the value. How can we make sure units are right and converted values are right?

pacco788 commented 11 months ago

Ouch, didn't see that. 40051 wasn't in use in my setup. Activated it for now.

The value of EB100-BS1 Air flow (40050) in HA is the same as in the NIBE display (m3/h), that's correct. 40051 is a tenth of 40050. I could solve this in HA for myself, but I don't know how to suggest a value for that. m3/h/10 sounds not very charming ;-)

Greate there is an issue opened! @yozik04 not sure how you can make sure that values are correct. But at least there is a need to override values from the modbus manager. Beside of the missing units for 40050 and 40051 and the factor, there is also wrong units for fan_speed_current_43108 it is shown as % but the value is the selected Fan mode e.g. a value between 0-4 @pacco788 is that the same for you

You need to fix this by mainly adjusting the extension filer here: https://github.com/yozik04/nibe/blob/master/nibe/data/extensions.json and running the generation script (https://github.com/yozik04/nibe/blob/master/README.md#2-convert-source-csv-files-to-json)

Thank you @elupus reading the doc more closely may have helped me ;)

I will fix: sensor.eb100_adjusted_bs1_air_flow_41026 sensor.eb100_bs1_air_flow_40050 sensor.eb100_bs1_air_flow_unfiltered_40051

all of them affects only F750 and f730. Having a f730 I can test it: image

For the Fan speed current I will create a separate request... As they are used by different Models and I'm unsure if all have the same issue... Do you have tester for: f370_f470 f1145_f1245 f1155_f1255 f1345 f1355

For my F730 this makes more sense: image than: image

My Nibe app however shows 30% - 30% is configured for Mode 2 on my system.

yozik04 commented 2 weeks ago

Do you have the last version of the firmware?

I thought that all F1xxx series are ground heat pumps. No idea if these can have any fan unit attached.

tizianodeg commented 2 weeks ago

I just checked where the id is used: https://github.com/search?q=repo%3Ayozik04%2Fnibe+41258&type=code Guess it depends if a ventilation is installed or not like a Exhaust air module FLM?

No idea I can only test my F730, could do the change also only for the f730/F750 guess they should behave similar. Let move the discussion on current fan speed to #164. For the Air flow I created a PR it only affects F750 and F730 as they are the only one with those parameters.
