Add Slat service to an air conditiner or fan

[royfocker19]

Hello everyone, I was trying to add a SLAT to a Heater_Cooler or a FAN, I should see the swing mode but I can't see it. Does anyone have an example of the utilisation os SLAT service?

[maximkulkin]

Here is my accessory that has swing mode

Hi Maxim, I already tested that, but I wanted to use the specific service for slat to have what is described here:

I want to have the possibility of having the slat closed, fixed or swinging. I don't know if it works that way, but maybe if slat is set to fixed or jammed, you could specify the current tilt angle.

[maximkulkin]

In that case you need to add a Slat service with slat characteristics

[royfocker19]

I’m doing that, but it doesn’t show up on de accessory. I’ll share my code

[maximkulkin]

Are you still planning to share your code?

[royfocker19]

Yes sorry, I didn’t have the pc with me till today, I went through a surgery last week. I will share it in a few hours.

Can you also provide definitions of all characteristics used in there

Are you using the Home app to check this? Not every service is properly displayed in there.

[maximkulkin]

It looks kind of correct, it might be the problem is somewhere else. Also, it would be nice to set primary service for you accessory (e.g. Fan)

[maximkulkin]

Ok, I tried to create simple Fan & Slat accessory and there seemed to be no Slat seen. So I removed fan and left just a Slat. And what I've found is that it paired OK, but in Home.app it showed as generic accessory with message "This accessory is not currently supported by the Home app.".

I guess, at this point we can close this issue. Left me know if you have more questions.
