I merged your PR and made some small changes. But I will not release until above error is fixed. And when adding a new device in Homey the message 'migrating, please wait' is gone. The UI just shows the device as unavailable, so user has no clue what is going on.

Also my linter has an issue with this code (the ?). if (values?.light_mode === 'temperature') {

Can you check/fix it? PS: Im traveling this week. So will be next weekend before I have a chance to merge and test.

Will do that, maybe it's a nice idea to add automatic linting to PR's?
