The bridge does not care what the A-B-C switch is set to on the sensors.
The A-B-C switch just sets an identifier in the data stream so sensors can be told apart by the consoles. It does not change the frequency of the radio transmission.
The bridge only decodes 433MHz data from sensors it thinks it understands. Sometimes it gets it wrong for non-compatible Acurite gear. Usually it will ignore non-Acurite sensors on 433MHz, but there's a chance they might also be mis-identified.
All 5n1 sensors are compatible with the bridge, including the one with the 01515 kit.
