But my AC plug/adapter that plugs into the outlet buzzes very loudly. Significantly loud. Not something I would consider within a normal acceptance/tolerance.
Is this normal for your plugs? If not, what should I do?
@holtzco - send an email into support@rachio.com explaining the situation and I think they’ll send a replacement unit out PDQ. Be sure to specify which Generation (1, 2 or 3) device you have. Rachio provides a two year warranty and they’ve been good about that.
@DLane is right, the solution will most likely end up being to contact the support, but just for my personal curiosity, can you please perform a couple of tests?
Does the transformer buzz without load / while rachio is disconnected?
Does the transformer buzz while plugged into a different power socket elsewhere at home?
It would help to figure out if the root issue lies with transformer (likely) or wiring (worth a check).
