What device is this? How was the attribute "chime" defined? Chances are it was incorrectly defined as something that doesn't exist or maybe boolean isn't working. I couldn't find an example of it anywhere on a google 'site:github.com "hubitat" "bool" "attribute"' search.
I most often see attributes defined as type "string", "enum", or "number" but "bool" should work according to this.
