I am sorry, I don't have acces to my weewx database now. I will check and post the database data later.
The almanac is the set of historic records stored in the weather station internal memory. It can be (and actualy was) obtained by calling wee_device --history The almanac records are very similar to - if not the same as - loop records obtained via USB connection by weewx. mph Dne úterý 20. srpna 2019 7:46:20 UTC+2 Andrew Milner napsal(a): > > what are the database values for rain? > > not sure what the almanac is - or do you mean database? does your > database store rain, ticks or both? > > > > On Tuesday, 20 August 2019 08:02:07 UTC+3, mph wrote: >> >> Ok, >> >> I've decoded all the almanac data and there is an excerpt: >> >> 01:19:00, 265 ticks >> 01:49:00, 267 = 2 >> 02:19:00, 268 = 1 >> 02:49:00, 271 = 2 >> 04:49:00, 272 = 1 >> 05:49:00, 273 = 1 >> 07:49:00, 274 = 1 >> 08:19:00, 275 = 1 >> 10:49:00, 276 = 1 >> 19:19:00, 279 = 3 >> >> As you may see, my almanac has 30 min interval, all times are local time. >> Between 01:19 and 03:00 local time there are 5 ticks recorded, but weewx >> shows just 4 ticks.
