Rain gauge problems 10.113x

I’m not sure whether this is a bug or a misunderstanding.

I have the AAG rain gauge counter with the backup lithium battery.
It is one month old.

My understanding is that it keeps track of the rainfall dumps even if WD is not running or the computer if off.

Last night we had a big series of thunderstorms. The power went off at 1AM local. The glass rain gauge showed 2.2 " of rainfall.

Now power is back on and WD was restarted.

WD shows only 0.2" accumulated. It appears not to have picked up any of the rain which accumulated after the power went off.

Is this a bug or a misunderstanding?

hi
yes, its supposed to work that way, in theory, but i never quite got it to jell

there is alable on the dallas 1 wire setup page that, rain since program was last running…see if there is a number there…and then use that to increase the rain totals, under setup, control panel, baromeeter offset, rainfall , etc

i will see if i can mimick having a rain guage here…and test…
so much to do …

Should have looked immediately upon restarting. Have had several restarts since this morning. Right now it is zero. Zero is correct since no rain has fallen between any of the restarts. Did manually increment the amounts by an estimated amount. BTW version is 10.13x not 10.113x.

Didn’t know if the problem was because of the crash type shutdown of the program caused by the power outage. Presumably the value is stored in some kind of random file and some recent value for the last counter amount would have been stored.

Clearly this crash scenerio is just when one wants this feature to work. We have very few power outages in clear wx…

While playing with the rain gauge trying to “debounce” it, I used the AAG software. It clearly was able to “remember” how much “rain” had fallen between runs. One could directly see the values of the two counter registers.

What I expected to see upon startup was a spike in rainfall on the plot and the rainfall amounts appropriately incremented.

I’d do some more fooling around but the gauge is now on a radio tower and would have to climb. Can do but as last resort.

By the way, the rain fall amounts on the 0- 4 " plot scale suffer from round off problems. It shows the following amounts at tics 0, .4, .8, 1.2, 1.6, 2.0, 2.4, 2.8, 3.1, 3.5, 3.9 . The last three showing the roundoff problem.
