Invalid payload in SensorMultiLevelReport #78

Open RicoSuter opened 11 months ago

RicoSuter commented 11 months ago

Somehow my ZWave Stick reports wrong payloads - is there maybe some bug in this library (not according to specs) or is my ZWave controller not working as expected? Can we maybe fix this so that a 2-byte response is also allowed?

Payload should contain at least 3 bytes: Sensor Type | Size | Value

Payload: 01-03 Byte 1: Sensor Type: 01 = Temperature Byte 2: Size (3 bits): The size field indicates the number of bytes that used for the sensor value. This field can take values from 1 (001b), 2 (010b) or 4 (100b).

3 is an invalid value and the sensor value is missing
