Address Types

Depending on your doorbell system the device addresses can have a different length and structure. If your receiver log shows addresses like [XXXX > XXXX] your system uses 2-byte addresses. For 3-byte addresses the format is [XXXXXX > XXXXXX] and you need to set three_byte_address: true when transmitting any messages to the bus.
