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!
