Thank you ray63, to your question, all i need is to save to a cloud some exception messages of the forme
Local time ... Internet shortage from x to y
Or
Local time ... Pir sensor bitmap 001 111 000
Or, every 15 minutes
Local time... I am Alive
Or
Local time... Starting up
What do i do with the data? I simply read it with my phones chrome browser. I can see for instance if i had a mains shortage, an internet failure, or the infrared activity around my house so as to set an intrusion discriminator. In short, arduino sends some messages, i (hunan) read them in my leisure time and use the data to improve my project.
The project mainly for home surveillance for when I'm away
Thanks again
