[New Device] TCM / Tchibo Weather Station 602012
Hi team, I captured and decoded a currently unsupported weather sensor sold by Tchibo/TCM in Germany and Austria.
Device: TCM / Tchibo 602012 (DC 3V)
Modulation: OOK / ASK (PWM in Gaps)
Frequency: 433.92 MHz
Payload: 42 bits
Measured Timings (approx):
Pulse: ~480 µs
Short Gap (Logic 1): ~1950 µs
Long Gap (Logic 0): ~3900 µs
Sync Gap: ~8300 µs
Payload Structure:
[Temp] [ID] [CRC] [Hum] [Status] (e.g. 41 86 7F 58 1)
Temperature: (Decimal value of Byte 1 - 17) / 2 (e.g., Hex 41 = 65 -> (65-17)/2 = 24.0°C)
Humidity: BCD encoded in Byte 4 (e.g., Hex 58 = 58%)
Attached are the .sub files and pictures of the device. Let me know if you need more samples!
