|
|
* LaCrosse TX 433 Mhz Temperature and Humidity Sensors.
|
|
* - Tested: TX-7U and TX-6U (Temperature only)
|
|
* - Not Tested but should work: TX-3, TX-4
|
|
* - also TFA Dostmann 30.3120.90 sensor (for e.g. 35.1018.06 (WS-9015) station)
|
|
* - also TFA Dostmann 30.3121 sensor
|
|
* Protocol Documentation: http://www.f6fbb.org/domo/sensors/tx3_th.php
|
|
* Message is 44 bits, 11 x 4 bit nybbles:
|
|
* [00] [cnt = 10] [type] [addr] [addr + parity] [v1] [v2] [v3] [iv1] [iv2] [check]
|
|
* Notes:
|
|
* - Zero Pulses are longer (1,400 uS High, 1,000 uS Low) = 2,400 uS
|
|
* - One Pulses are shorter ( 550 uS High, 1,000 uS Low) = 1,600 uS
|
|
* - Sensor id changes when the battery is changed
|
|
* - Primary Value are BCD with one decimal place: vvv = 12.3
|
|
* - Secondary value is integer only intval = 12, seems to be a repeat of primary
|
|
* This may actually be an additional data check because the 4 bit checksum
|
|
* and parity bit is pretty week at detecting errors.
|
|
* - Temperature is in Celsius with 50.0 added (to handle negative values)
|
|
* - Humidity values appear to be integer precision, decimal always 0.
|
|
* - There is a 4 bit checksum and a parity bit covering the three digit value
|
|
* - Parity check for TX-3 and TX-4 might be different.
|
|
* - Msg sent with one repeat after 30 mS
|
|
* - Temperature and humidity are sent as separate messages
|
|
* - Frequency for each sensor may be could be off by as much as 50-75 khz
|
|
* - LaCrosse Sensors in other frequency ranges (915 Mhz) use FSK not OOK
|
|
* so they can't be decoded by rtl_433 currently.
|
|
* - Temperature and Humidity are sent in different messages bursts.
