Watshome YT6018-2 weather station
The Watshome wireless sensor is realy a Fujian Youtong device see http://www.youtonggroup.com
With the protocol analyser from www.nethome.nu I got the following sample:
Error creating thumbnail: Unable to save thumbnail to destination
The 8ms gap is the start of the package. A '1' is a pulse followed by a gap of three times the pulse duration. A '0' is a pulse followed by a gap of the same duration as the pulse.
so in the example the package is:
1111 1010 1010 0000 1100 1011 1111 0000 0000 ---- ---- --CC TTTT TTTT TTTT ---- ---- ---- F A
CC is channel 00 ch1 01 ch2 10 ch3
T is the temperature times 10
In the above example the temperature is 0000:1100:1011 which is 203. So it is 20.3 degrees Celsius.
1111 1010 1000 1111 1101 1011 1111 0000 0000 ---- ---- --CC TTTT TTTT TTTT ---- ---- ----
the sensor on channel 1 has 1111:1101:1011 which is -37. -3.7 degrees Celsius.
