So i ordered 2x 2.7 50F capacitors and began to upgrade.

With 100F, is the battery even necessary? Can it run all night on the super caps?
Perhaps pulling the battery out overnight might help show whether it can or not. It should be in the "worst case" which would be winter, which we are now past. (at least on this side of the Equator  :grin:)

As an engineer, I view Davis' design as rather elegant.

Solar panel to provide environmentally-friendly free power most of the time.
Supercap, charged by the solar panel during the day, to provide power at night.
A dry battery to provide a bit of power if there was not sufficient stored energy in the supercap (cloudy, etc.)

AND that battery provides days of full-time power in the event the solar panel or supercap completely fails, thus providing time to diagnose and correct the failure without major loss of data.  And of course the system monitors the battery voltage to provide several days of notification that there is a problem.

If the battery suddenly fails for some reason, the system will still continue to operate with perhaps some loss of before-daylight data.  And, of course, will provide warning of the situation.

[Oh, and the option of providing external power through the included jack.]

Going to a system of just solar-panel-plus-rechargeable-battery would:
1.  Require a substantially larger solar panel.
2.  Complicate the ability to diagnose impending battery (or solar panel) failure. (Less reliable warning)
3.  Cause total loss of data if, for some reason, either the solar panel or the battery suddenly fails.

But what about those of us who ONLY want to use WL-IP to get our data over to CWOP?

then you do not have to worry about that. You go to setting which is a wrench  and check the boxes.  However... I do recall Davis saying they were going to take all the wl1.0 accts and move them to 2.0 sometime during the 2nd quarter of the year, which we are there.
Yep, that is what I was alluding to.

Call off the Calvary :!:. I just refreshed the page. Looks great. Thanks, Jerry for taking a look. Ken, you can go back to sleep ... :grin:

Poking around in the forums tonight and discover that we are all about to lose our free
API access to Wunderground. According to the forums many Private weather stations are
already abandoning the WU ship as they are not keen on providing data for a company (IBM)
that plan to sell the data for profit.

Reading more into the forums, monthly API data packages will start at around $800 per month.
WUnderground no longer replying to emails, forum posts or support tickets and their contact telephone numbers have been disconnected.. Sucks for paid or paying API members!

Looks good here, Breezy!  I'm not sure what the problem is you're referring to.

Ken,

Not sure as to what's going on but I probably didn't follow your installation instructions correctly. Maybe something to do with the "cache" as I was running the previous version?  http://indiantrailweather.com/wxmesonetmap.php   :oops:

Thanks for all of your time and effort. Much appreciated!  =D>

Many many moons ago, I collected data from an inadvertent experiment when the battery in an ISS went dead and wasn't noticed for a couple of weeks. In looking back at the database, in late November at about 35 N 120W, on close to the least daylight time of the year, the stock ISS started up promptly a little after local sunrise, and ran for about 11 hours after sunset. This behavior was consistent over several days.

It remains unknown if the limiting factor was solar output or capacitor capacity.

Do check out your ./WL/NOAA-reports/ directory on the webserver and remove any files that don't match NOAA*.TXT names.  I've seen instances where some rogue files disturbed the script.

For the atom-top-warning.php error, change line 874
Code: [Select]
  $total_time = '';
to
Code: [Select]
  $total_time = 0;
