After upgrading to ios 15, I noticed that Siri now says that she cant lock/unlock a door via the HomeKit integration even though the action still happens. She is happy controlling lights/switches as before. It just seems to be a problem with locks. I tried re-adding the bridge, to no avail. Anyone else seen that?
I am also having this issue… I don’t often use Siri to do much but since noticing I tried a few days in a row and same thing… she says she is unable but it always works… … I am using An Apple Watch to make the request…
So oddly enough the day after I posted this it has now been working successfully when using my watch… multiple days in a row but usually only once a day… it just worked again on my way in tonight. Is yours working now also?
