Sorry I got distracted this last week and wasn't able to send requested screenshot or give feedback. Looks like you fixed it as it's working perfectly on my end now
Tiny bug I noticed which doesn't affect functionality is if you set bulb hue to 0, the summary of the button app will state H:(!Missing!) instead of H:0.
Not a bug, but another slight usability suggestion would be when setting a button to speak a notification, instead of formatting as "Send Msg To : [Bedroom Sonos]", it could be formatted something like "Speak Msg 'Nightlight engaged' On: [Bedroom Sonos]".
Thanks for your hard work on this app!
