I have 2 HomeKit homes. The 2 HomeKit homes are actually in the same house, but one of them is for limited use only (contains a bridge that I want to share with others) and the second one is what I normally use with Lutron and other bridges. Over a year ago, using the Lutron Caseta iOS app, I added my Lutron Caseta Smart Bridge PRO (L-BDGPRO2-WH) to one of the two HomeKit homes. The Lutron Caseta and Apple HomeKit integration has been working great ever since. I have no problems with the integration at this time. I can control Lutron devices from either the Apple Home app, or the Lutron Caseta app, or by physically turning on and off the switches, and the Lutron Caseta and Apple Home apps control the devices and show the correct status.
In the past, I recall that the Lutron Caseta app's Settings page correctly showed that Caseta was properly integrated with Apple HomeKit. I haven't looked at the Caseta app's Settings page in months, since everything is working fine. However, I went to its Settings page recently just to check things, and what has me puzzled is that I noticed that the Lutron Caseta app's Settings page, says that there is "No integration linked". I have the latest Lutron Caseta app as of today, version 22.5.3, (and also in at least a previous version), the Caseta app's Settings page has been saying "No Integration linked". When I select "Integrations->Apple HomeKit", I get this message:
"Your Bridge/Main Repeater/Processor may have been paired with another iCloud account, or is not ready for pairing yet. Please ask to be invited by the account that set up the system (they can invite you using the Home App). Also check iOS Settings to make sure that the Lutron app has access to HomeKit."
Again, my Lutron Caseta system and Apple HomeKit integration is working fine. I was able to remove and add a Lutron Caseta device recently, and I can control Lutron devices with HomeKit just fine. It just bugs me that the Lutron Caseta app's Settings page says "No Integration linked". I plan on setting up a lot of HomeKit automations soon, and I don't want there to be any future problems if there is some underlying issue that might cause future problems.
Any reason why the Lutron Caseta app thinks that integration with HomeKit has not been done, even though it has, and is working fine? I'd rather not have to do any resets, since things are working okay.
