Realize this isn’t strictly smartthings, but I’m not sure where else to look. Skybell support isn’t being terribly helpful.
My chime (analog, mechanical) recently started buzzing/humming. Doorbell transformer is fine (Skybell is trying to convince me that’s it), but it appears to be entirely the chime. Anyone had this before? Have a chime that they like and know works? Have a fix? I know Ring has a power board they supply with the Pro, and August seems to have some type of power unit they provide as well. Both jumper across the chime to resolve humming, but I can’t figure out what they actually are (maybe glorified resistors). One video doorbell manufacturer recommends just throwing a 10Ohm resistor in series (which Skybell also does if you don’t have a chime). I can certainly do that if we think it’ll fix the hum (which only bugs me when the house is empty).
