The most common EnOcean RORG values are RPS (F6, Repeated Switch Telegram, push-buttons), 1BS (D5, 1-Byte Sensor, magnetic contacts), 4BS (A5, 4-Byte Sensor, temperature / CO2 / lux sensors) and VLD (D2, Variable Length Data, modern multi-function devices).
True
EnOcean defines a small set of telegram families to match the energy budget and payload size of each device class. RPS (F6) carries 8 bits of user data and is used by piezo rockers. 1BS (D5) carries a single byte and is typical of magnetic contact sensors. 4BS (A5) carries four bytes and is used for analogue sensors that report temperature, humidity, CO2 or illuminance. VLD (D2) supports a variable-length payload for richer, modern devices such as metering or HVAC actuators. Secure variants (RORG 30 / 35) wrap any of the above with EnOcean Secure encryption.
When you sniff an unknown device, look at the RORG byte first: it instantly narrows the search space in the EEP catalogue from thousands of profiles to a few dozen.
