A doorbell chime bypass circuit includes a first node, a second node, and a bi-directional FET switch in series with the first node and the second current node. The bi-directional FET switch includes a first FET and a second FET in series, and is configured to cease conducting current between the first and second nodes when gate voltages of the first and second FETs are below a cut-off threshold. The bypass circuit further includes a sensing circuit configured to determine a level of current flowing through the bi-directional FET switch, and a switch controller configured to set the gate voltages of the first and second FETs to a level below the cut-off threshold when the sensing circuit senses that the level of current meets a doorbell press current threshold, causing the bi-directional FET switch to cease conducting current between the first and second nodes.
