More sensors for Tellstick local access

After obtaining local network access to the Tellstick net I also have a wind sensor and a rain sensor close to my Tellstick net. Again, translating the Telldus .cpp code to python, the following python code gives the same results as the Telldus Live page. The code for the 1984/1994 sensors are identical except for the:

checksum = checksum + 0x1 + 0x9 + 0x8 + 0x4

vs

checksum = checksum + 0x1 + 0x9 + 0x9 + 0x4

checksum calculation. Here are the python code.

Just add some more checks in the while loop

while 1:
try:
data,(address, port) = sock.recvfrom(1040)
#print data
if (data.split(":")[6][6:10]=="F824"):
#print data.split(":")[7][5:5+14]
print decodeF824(data.split(":")[7][5:5+14])
elif (data.split(":")[6][6:10]=="1984"):
#print data.split(":")[7][5:5+16]
print decode1984(data.split(":")[7][5:5+16])
elif (data.split(":")[6][6:10]=="2914"):
#print data.split(":")[7][5:5+16]
print decode2914(data.split(":")[7][5:5+16])
else:
print data
#fp.write(data + '\n');
#fp.flush()
except KeyboardInterrupt:
print "done"
#fp.close()
break
except: # time out, try again
pass
