I have the same problem. Someone sent me an email saying to reset it and check settings but I've done all that and it still doesn't function right. Mine is also freezing every few seconds. It's just not a good product. I'm currently waiting on a ring doorbell.

Not required. The installation instructions are based on utilizing your existing chime and existing wiring running from the chime to the chime button (at entry door). Consider also, the chime is typically running off of low voltage (10 - 12 volts); your existing chime is running off a low voltage transformer.
