[make-all]

The way this device splits its settings across multiple dps makes it difficult to support, unless that rather dipswitch like control interface is just simply copied instead of trying to integrate it as native Home Assistant entities..

[bepluy]

Dps 108 and 109 are just temp. and hum. sensors. Others are like dipswitches - on/off. Global switch - id 1, others are speed, vent. modes. And probably if you set "code": "speed_three" - to true, then other speeds become false.
So i think it's ok to integrate this device just with switches - and use it in scenes or automations.
Or we need to make it suitable for fan or climate integration ?

[perimos]

I would also welcome the support of the HRV KCvents and have tried my hand at a device configuration. Due to this special distribution to individual dipswitches, I was unable to work out a nice solution.

@make-all: are you planning to support this special behavior at some point or have I overlooked how to do it? It would need something like that:

ID 104	ID 101	ID 102	ID 103	speed percentage
1	x	x	x	0%
0	1	0	0	33%
0	0	1	0	67%
0	0	0	1	100%

Without this functionality, the device would look like this (ugly, but works in general):

[make-all]

No, I don't have any plan to cater to this type of multi-boolean instead of integer encoding in the short-medium term.
If you want to add an ugly config based on what is possible, then I will include it.

[perimos]

Thank you for your feedback. I will test a little more and open a pull request in the next few days.

[make-all]

I might suggest instead of Speed 0,1,2,3, you could use Speed 1, 2, 4, 8 which gives some hint that you can add them to create speeds up to 15.

[perimos]

No, unfortunately it is not the case that the fan offers 15 levels. It only has 3 levels (33%, 67%, 100%) and the sleep mode (0%). However, I have seen in the meantime that the device overwrites the other modes in sleep mode and sets the bit at 33% for speed.
I therefore suggest adding sleep mode to the other modes:

[make-all]

In that case you might be able to use value_redirect to chain the values. I thought they had to be all added, which would make it impossible with the current capabilities of the integration.

Something like:

  - id: 101
    type: boolean
    name: speed
    mapping:
      - dps_val: true
        value: 33
      - dps_val: false
        value_redirect: speed2
  - id: 102
    type: boolean
    name: speed2
    mapping:
      - dps_val: true
        value: 66
      - dps_val: false
        value_redirect: speed3
  - id: 103
    type: boolean
    name: speed3
    mapping:
      - dps_val: true
        value: 100
      - dps_val: false
        value: 0

I'm not 100% sure this will work, as I haven't chained value_redirects in any previous config, but if it does it might allow a better interface (a fan entity rather than a group of switches)

[perimos]

Thanks for the suggestion. It correctly shows the speed in HomeAssistant when I set it in the app. However, it is not possible to control the speed from HomeAssistant.

Do you see any other solution with more options? Or would the options 66% and 100% already have to be “announced” in ID 101?

Unfortunately, it's my only fan in my system, so I don't have a working example to make comparisons. But perhaps interesting: in the developer tools it shows the attribute “percentage_step: 100”. Shouldn't that be set to 33% for the 3 possible states?

[make-all]

Maybe they need to be announced in the speed dp, as you say. I don't know if it will be possible to do this, as using dummy values will lead to incorrect behaviour. The current code only really deals with two linked dps, any more just makes things exponentially more complex so I didn't implement it.

[perimos]

I'll play around a bit and get back to you as soon as I have time. But thank you very much so far.

[perimos]

The following seems to work:

    - id: 101
      type: boolean
      name: speed
      default: false
      mapping:
        - dps_val: true
          value: 33
        - dps_val: dummy_speed1
          value: 66
          value_redirect: speed2
        - dps_val: dummy_speed2
          value: 100
          value_redirect: speed3
        - dps_val: false
          value_redirect: speed2
    - id: 102
      type: boolean
      name: speed2
      default: false
      mapping:
        - dps_val: true
          value: 66
        - dps_val: false
          value_redirect: speed3
      hidden: true
    - id: 103
      type: boolean
      name: speed3
      default: false
      mapping:
        - dps_val: true
          value: 100
        - dps_val: false
          value: 0
      hidden: true

Is there anything against it? If not, I would do the same for the modes during the next week.

[make-all]

If it works and does not result in the dummy values being sent to the device when setting any of the options (which might cause problems), then it should be OK.
