* Decode Ambient Weather F007TH, F012TH, TF 30.3208.02, SwitchDoc F016TH.
|
|
* Devices supported:
|
|
* - Ambient Weather F007TH Thermo-Hygrometer.
|
|
* - Ambient Weather F012TH Indoor/Display Thermo-Hygrometer.
|
|
* - TFA senders 30.3208.02 from the TFA "Klima-Monitor" 30.3054,
|
|
* - SwitchDoc Labs F016TH.
|
|
* This decoder handles the 433mhz/868mhz thermo-hygrometers.
|
|
* The 915mhz (WH*) family of devices use different modulation/encoding.
|
|
* Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
|
|
* xxxxMMMM IIIIIIII BCCCTTTT TTTTTTTT HHHHHHHH MMMMMMMM
|
|
* - x: Unknown 0x04 on F007TH/F012TH
|
|
* - M: Model Number?, 0x05 on F007TH/F012TH/SwitchDocLabs F016TH
|
|
* - I: ID byte (8 bits), volatie, changes at power up,
|
|
* - B: Battery Low
|
|
* - C: Channel (3 bits 1-8) - F007TH set by Dip switch, F012TH soft setting
|
|
* - T: Temperature 12 bits - Fahrenheit * 10 + 400
|
|
* - H: Humidity (8 bits)
|
|
* - M: Message integrity check LFSR Digest-8, gen 0x98, key 0x3e, init 0x64
|
|
*
|
|
* three repeats without gap
|
|
* full preamble is 0x00145 (the last bits might not be fixed, e.g. 0x00146)
|
|
* and on decoding also 0xffd45
