HomeKit Bridge blind covers no longer open and close

[ZetaPhoenix]

The problem

After updating to 2021.8.x I was no longer able to use voice commands or tap on the blind covers to open and close them as I could before.

The blinds still respond if I manually set the tilt angle but do not respond to open or close commands from the iOS devices.

core-2021.8.7

What was the last working version of Home Assistant Core?

Hey there @bdraco, mind taking a look at this issue as it has been labeled with an integration (homekit) you are listed as a code owner for? Thanks!
_{^{(message by CodeOwnersMention)}}

[bdraco]

Please post a dump of the state of the blind from the developer tools.

Also which integration provides it

It sounds like the supported features might be missing a bit

[ZetaPhoenix]

current_tilt_position: 50
friendly_name: Main Bedroom Blinds
assumed_state: true
supported_features: 187
device_class: blind

This is provided by ESPHome yaml. The cover still works just fine with the open and close buttons in HA but it seems the command from HomeKit does not show up in the logbook.

[ZetaPhoenix]

Ah, the image shows them closed right now but if I open them then the status updates and the tilt_position also changes. Right now Open sets the tilt position to 50% and closed to 100% as I have not added lift motors yet.

[bdraco]

Its missing SUPPORT_SET_POSITION so its not bucketing correctly.

>>> 187 & 4
0

[ZetaPhoenix]

Did this change between 2021.7 and 2021.8?

[bdraco]

Yes. It regressed in #53130
