Every time my logger gets a lot of data that hasn't been sent to weewx because system is offline (like power outage for last 2 days), the system comes up, vantage driver fails a CRC16 error well documented and then the only thing you can do is manually pull all the power to the envoy and restart weewx. it will download some data to the database and then get an error again and exit the vantage driver. You may get and hour or 2 of data and then have to stop, pull power, start weewx and view log.
I used to have the data being pumped to CWOP and WUNDERGROUND. I turned off CWOP and it behaved slightly better but it seems as soon as a WUNDERGROUND record went out it would stop working pretty close to that point. Today I decided to do a wee_device --dump. I'm confused why using the exact same drivers it has no problem reading and streaming all the data in to the database (obviously error-ing out on duplicate keys) and never gets a CRC error. Obviously no WUNDERGROUND data is sent but the process does finish. If I then start weewx, it goes right in to the loop process and doesn't fail. I know people have chased the USB cable, power supply (my logger is wrapped in AC duct foil tape (including the cable) and has a 2 ferrite ended cable. Doesn't help. Power supply is new and fine on Rpi. I think it may be the vantage driver and trying to pause during a push to one of the services while downloading all this data. Can't prove that but that is my observation. I modified vantage.py today to allow me to not have to say yes to the dump command with a --dumpauto option. I took weewx out of rc.d and run a job a startup using cron that calls wee_device --dumpauto and then immediately starts weewx. While that is the backstory, what am I missing by taking this approach that at least has the system back up and running when the power goes down or multiple hours of data end up on the logger without weewx running? I get I am probably not getting data to wunderground for all those periods. it is in the database. not sure what else to try. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
