Unable to connect shutters via matter to Homekit

[maltic42]

Hello,

I am using an ESP32 development board with new latest version of Tasmota (14.0.0). I tried to create a kind of prototype to check how shutters or blinds are exposed via matter to Homekit and Google Home.

Therefore I created to relays in the configuration (the GPIOs are not connected), added the commands

SetOption80 1
ShutterMode 0
Interlock Off
Interlock On
Interlock 1,2
ShutterMode 1

The startup looks like this:

00:00:00.515 SHT: About to load settings from file /.drvset027

The UI displays up and down arrows, open close sliders and ON/OFF above the arrows, the virtual shutter can be opened and closed.

Now I want to expose the shutter via matter to Homekit. I added one device to matter (type Shutter and parameter 1??). When I connect to Homekit, the device (shutter) is added, but Homekit says there is no answer. Same in Google Home.

What parameter do I have to add?

I can answer my own question. Everything works when settings 0 as the parameter, not 1. I do not know if this is a bug, but setting 0 exposes the blinds Shutter 1 as a matter device. However I think I found another bug, when adding shutter + tilt the device hangs after about 20 seconds and has to be rebooted manually. I will open an issue.
