HomeKit Scene Failed

I had never had a problem with my any of my HomeKit scenes working until just the last couple weeks or so. It only seems to be one scene that I’m having a problem with.

The scenes in question seem to be:

Goodnight:

Turns off the Lutron Caseta dimmer switch (lights)

Turns off 7 Philips Hue lights

Turns on iDevices plug in outlet for box fan

Turns off 2 iDevices nightlights

Locks August Smart Lock (this is the regular August Smart Lock from before the Smart Lock Pro)

If I try to activate this scene via Siri she just tells me, “Your secure scene is still in progress. To confirm, ask me about your secure devices again in a few moments.” And nothing is triggered (including the lock). The strange thing is that I have additional scenes that trigger the lock and there are no problems. If I remove the lock from the scene it still fails, and if I try to trigger it through Siri without the lock she says, “Setting your scene with HomeKit...” But nothing happens.

Now what’s really strange to me if that if I open the scene in the Home app, check the details, and select “Test This Scene” everything works perfect including the door locking. I have no idea what’s going on, there seems to be no consistency here. Again, it’s only one scene working and I’ve tried removing devices that aren’t in other scenes and it still refuses to trigger, I’ve tried deleting the scene and re-adding it and nothing seems to work.

Anyone else having an issue like this? Anyone able to off help, please?

Additionally, this happens whether I attempt through the app or via Siri on my or my wife’s iPhone 6s, my iPad Pro 10.5, my HomePod, my Apple TV 4th gen, my Apple Watch, or my wife’s iPad Mini 3.
