Just installed my first Innovelli switch, a LZW31-SN dimmer. It replaced a dumb dimmer that, because it was connected to a pair of Philips Hue RGB BR30 E26 bulbs, was always set to the maximum level. There was no buzzing with the dumb dimmer.
I got it paired to my SmartThings hub and immediately disabled the relay. So far, so good.
But now one of the Hue bulbs buzzes whenever it’s turned on. It seems to only be one of the two bulbs, despite the fact that they’re identical. They did not buzz when connected to the dumb knob dimmer previously. The switch was set to full power when I disabled the relay.
In my SmartThings app the dimmer level is reported at 99%. When I drag the slider to 100%, after about 1 second when the “busy” circle fades it drops back to 99%. I don’t know why and there’s no perceptible difference.
The power meter reports 17w and the energy consumption is 8Wh.
I realize that it’s not an ELV dimmer, but since I was going to use it basically as a scene controller and not use the line load dimming function in the switch I wasn’t expecting any compatibility issues.
Has anyone had this buzzing with Hue smart bulbs before? How can I get rid of the buzzing?
