Well I think I found you on WU. You are IBLUMENA15 right? Your station is running the following firmware:
EasyWeatherV1.2.2
Therefore it is not an Ambient Weather branded hardware as I suspected. Ambient's firmware that their original WS-2902 ran was AMBWeatherV3.x.x. The EasyWeatherV1.2.2 that you are running indicates that you have some other Fine Offset clone brand.
So you are unlikely going to be able to upgrade your hardware to run Ambient firmware. Even if you managed to get it installed it still would not work because Ambient checks the stations reporting to ambientweather.net against MAC address hardware numbers that they sold.
There is a way for you to upload to ambientweather.net. You'll need a compatible ObserverIP device and you'll need a Meteobridge. Then you'll need to pay Ambient one time $150 for for the ability to upload to ambientweather.net. After paying for the $150 license they will enter in the Meteobridge MAC address into their allowed device list for uploading. You could also buy a prelicenced WeatherBridge from Ambient as that is the same as a Meteobridge with Ambient's license already registered (you still need the compatible ObserverIP).
You are tottaly right my friend, it itsnt a Ambient Weather branded station.
So, I think i can live without reporting to ambientweather.net, WU and weathercloud are enough to me.
Knowing that the sensor and console are the same, thats good to me and the station is working flawlessly and totaly accurate in my place.
Lastly, and just to know, do you think if i purchase a brande Ambient Weather 2902A console, will it work with my outdoor sensor, or they put some lock on the outdoor sensor too?
Oh yes, you find me on WU!!! Thats me.
And thank you so so much for all the help.
