HomeKit controller string indices must be integers

The problem

I am getting an error about string indices must be integers in my HomeKit controller which I use to control my alarm through the alarm control panel. This problem just started in the latest HA version- I have changed nothing about my configuration other than updating HA, and this integration has worked for a long time.

What version of Home Assistant Core has the issue?

2023.1.1

What was the last working version of Home Assistant Core?

2022.12.9

What type of installation are you running?

Would you please provide debug logs

Sure, thanks for taking a look. The error only happens on closing/opening during the shutter roller is opening or closing, hope this helps.

I opened a pull request:
Jc2k/aiohomekit#278

since I believe the problem is located in this lib and it fixes the problem at my home. Hopefully it will be included in next release of aiohomekit, next release of home assistant would need to update the dependency aiohomekit.

Happy to get feedback if I'm on the right track.
