Custom characteristic

[XciD]

Hello,

I'm trying to define a custom characteristic like here in nodejs:

const TypeChangeTrack = "00000047-0000-1000-8000-656261617577"

type ChangeTrack struct {
	*characteristic.Int
}

func NewChangeTrack() *ChangeTrack {
	char := characteristic.NewInt(TypeChangeTrack)
	char.Format = characteristic.FormatInt32
	char.Perms = []string{characteristic.PermRead, characteristic.PermWrite, characteristic.PermEvents}
	char.SetMinValue(-1)
	char.SetMaxValue(1)
	char.SetStepValue(1)
	char.Description = "Track Change"

	return &ChangeTrack{char}
}

When I add this characteristic, Home+4 report: No Response
Any pointer ?

Thanks for your project

It should work if you set a default value.

char.SetValue(0)

Is this still an issue?
