only one instance of rtl_433 can be running.  if you are running rtl_433 
directly, then running weewx with the weewx-sdr driver will fail.

welcome to the quagmire of keeping up with random changes to rtl_433.

this posting shows "WH1080 / WH3080":

https://groups.google.com/forum/#!searchin/weewx-user/WH3080%7Csort:relevance/weewx-user/X8f8t--TXII/9yShgF_0AwAJ

but apparently the version of rtl_433 that you are using does not have 
spaces, and the 'original' version of rtl_433 used another string.

sigh.

rtl_433 needs to put some structure to the 'model' field as well as to the 
number and types of other identifying fields.

david,

please try the latest sdr driver (0.29 as of 30may2017)

there were changes to the rtl_433 code in the past couple of months that 
broke the weewx-sdr driver when using fine offset packets.

the latest sdr driver *should* work with both the older rtl_433 and the 
newer version.

I am a relative newcomer, too, and am not involved in development or 
support of weewx, so I'm probably wrong, but, since no one has said 
anything,  here goes.

The IDENTIFIER string for FOWH1080Packet is "Fine Offset WH1080 weather 
station", and it appears that string is what is used to tell whether or not 
the packet is known.

So I think, but I am not sure, if you edit sdr.py and replaced your new 
string for the old then it will work.  It would probably be best to add a 
new parser for this new product string, but the string replacement would 
tell if I'm right or not.  Just back up sdr.py first.
