I have defined a Slider and a Setpoint widget for a Dimmer item that is bound to an MQTT topic:
Slider item=dg_LichtDachboden_Dimmer Setpoint item=dg_LichtDachboden_Dimmer minValue=0 maxValue=100 step=10
Changing the slider does in fact set the dimmer. But pressing the +/- keys on the Setpoint does not have any effect. The value published to MQTT when using the Slider is an integer (“10”). The Setpoint does send a floating point number instead “10.0”).
Is there a way to control the output format of a Setpoint?
