Regarding 3 the data logger does have the data. So why can't the sql database be reconstructed? One (hopefully last!) Question. Does the script you have for rorpi setup work with stock systemd. In preinstall step if I don't replace systemd with sysV does it still work ? -- You received this

Hi Praveen, 1) It will keep increasing in size as data is accumulated - the size will be dependent on archive interval and time (measured in years usually!) I wouldn't sweat on the size increasing to the point where it would be a serious problem though, or at least not before you became aware of

Re: [weewx-user] Re: Barometric pressure correction the right way

I ask the question because whenever I put the heating on I see a change to the barometer readings on my graphs which implies to me that the pressure is changed (it appears to fall as the temperature rises). My console is 2/3 up the wall (too high to even read, but good for sensor reception!)

Thanks Glen for such a detailed reply. A few more questions as i m doing my homework :) 1) The SQL database has data for how many days? 1 day? Wondering how it's size doesn't just keep increasing 2) If i do rapidfire on WU, WU would also maintain its own archive from live data i assume

Hi Praveen, It's on the first page, but I agree that it probably doesn't leap out at you. You can put it anywhere you like but the default is in memory. The filesystem layout is defined around an apt install of weewx. The directory /var/lib/weewx is moved into RAM and mounted as a tmpfs with a

[weewx-user] wee_import WU vs Cumulus

The reports are generated each archive interval so yes fairly frequently. The problem is the process that generates the reports generates from the last generated report to the current time, it doesn't 'fill in the gaps'. So when you first did the import weeWX would have generated the early 2013

[weewx-user] wee_import from WU

Hi, Can you be a little more specific with what you mean by 'the new records from April to Dec 2013 don't show up in the monthly or yearly HTML page'. I would not expect data from 2013 to be appearing on the month or year page, as those pages would be showing data from January 2018 and 2018

Re: [weewx-user] Re: Barometric pressure correction the right way

As far as I was aware the difference between pressure inside and pressure outside is negligible (unless of course you live in a sealed house). So deriving barometer and altimeter using inside pressure rather than outside pressure has negligible effect. Of course if you use inside temperature

Tom - this has always baffled me - when the pressure reading is taken from an indoor console which is at a different temperature than outdoors. Maybe Tom knows the answer - if one carries a console from inside at 20 degrees o outside at 3 degrees does the pressure recorded on the console

RE: [weewx-user] Re: Barometric pressure correction the right way

The inside temperature does not enter the calculation. You are correcting for the weight of the air column outside, which is a function of outside density, which is a function of outside air temperature. -tk Fat-fingered from my Android On Jan 13, 2018 8:59 AM, "'ml' via weewx-user"
