This firmware 2.25, for now, is working very well.
Yesterday I had my adsl down for about 18 hours, on the return of the adsl I found myself on WL.com all the data, even those of when I had no connection. I'm using the wifi logger with uploads on WL.com every 2 minutes, in case of internet shortage, how many hours or days can the wifi logger accumulate data with my update interval?
If the power goes out and the batteries run out too, do I lose all the configurations of my wifi logger?
Normally weather services takes real time data. WL.COM works different. It take real time data (please set to 1 min WLIP and WL PC standard). It is only current data they make no history from it. History charts are from data logger memory which WiFiLogger contains.
Only WL.COM and PHP&MySQL use history data from data logger memory. Cumulus and WL PC as well, but those are not weather services.
Problem is in two connections:
1. Ask for last entry date.
2. Send data from this moment from point 1.
WeatherUnderground will accept history data, but it gives no feedback information about last entry. So this is not easy to make. I will try in the future.
BTW. Real time data is being send to WL.COM by WLIP/WL PC/WiFiLogger in 1 min. interval, but this can be change in WiFiLogger to 3 sec. RapidFire on WL.COM
Who would like to test it? Firmware change is needed for that.

About firmware 2.25. It contains new set of libriaries from producer of WiFi chip. I was expecting better working.
I had never more than 14 days without reboot. Today I have 20. This also means, that I didn't make any firmware changes for 20 days

WiFiLogger is working like a pipe. Takes data from console and send it to the Internet.
WiFiLogger keeps all settings in flash memory. It can be power on off 20 times per minute, no problem.
We should take care of console and console data. Console should be stand by 100% of the time.
I like backpowering from MeteoPi. I will do it with WiFiLogger. All units around the world can be made as back powering using soldering iron. This means no one will make it
I will try to put to the shops version with cable. How it will work?
- You are not connecting power supply to console, but to special wire which is soldered to WiFiLogger and it should be taken outside.
- Console is powered through diode.
- When there is no AC power then WiFi chip is off. No WiFi ability, but no power, no WiFi from router. Console has own batteries for itself and data logger memory.
Console can work as remote thermometer for 1 year on batteries.
Console can work as logging thermometer for 3 months. (console + data logger RS232/USB/WiFiLogger with back powering)
I would like to provide version of WiFiLogger which will have power cable (not nice looking). This version will be able to restore battery backup in console.
Console with WL IP can work on batteries 3 days
with WiFiLogger1 3 days
with WiFiLogger2 1 day.
All modern loggers are destroying console battery backup functionality. WiFiLogger with power cable will restore it.
