When receiving packets from a Ventus WS155 vind sensor, the temperature is wrong see example:

The correct temperature can be seen on the "'Alecto' id='2c:01'" humidity sensor, as this is the same device.
The wind sensor alternates between two different packets, one with temperature and humidity and one with wind speed, according to http://www.tfd.hu/tfdhu/files/wsprotocol/auriol_protocol_v20.pdf
Thus the packets from RTXcom-device must include some other data or some junk.
Could this be filtered out ?
Acrording to support at RFXcom, the first byte string 0x10 0x56 0x07 0x05 0x2c 0x01 0x00 0x87 0x00 0x04 0x00 0x08 0x68 0x74 0x20 0x52 0x69
represent a WIND, subtype WIND7, which does not include temperature information, the RFXmanger decode the result as:
Packettype = WIND
subtype = WIND7 - Alecto WS3500,WS4500
Sequence nbr = 5
ID = 2C01 decimal:11265
Direction = 135 degrees SE
Average speed = 0.4 mtr/sec = 1.44 km/hr = 0.89 mph
Wind gust = 0.8 mtr/sec = 2.88 km/hr = 1.79 mph
Signal level = 6 -72dBm
Battery = OK
I think that the temperature information should be left out for the subtype 7 0x07: 'Alecto WS4500'
.
Looke like WIND6 might be same:
2020-07-19 05:39:54:566
Packettype = WIND
subtype = WIND6 - LaCrosse WS2300
Sequence nbr = 1
ID = 4E00 decimal:19968
Direction = 90 degrees E
Average speed = 0 mtr/sec = 0 km/hr = 0 mph
Wind gust = 19,3 mtr/sec = 69,48 km/hr = 43,17 mph
Signal level = 6 -72dBm
Battery = OK
