Hi all,
Recently I am bussy with a tsl2591 on a Landid&Gyr kWh meter power use read-out. This is working on a arduino.
The next step is to read out and have the reading on internet.
To do so I bought a esp12E and up-loaded this with the arduino script. Working.( local wi-fi )
Now I would like to have the light and kWh reading on the webpage as wel. (outside local wi-fi )
I like to use the graph already in the script.
As internet is still a bid fuzzy ( do I need realy an website? for a PHP script????)
BTW download and install. of the php script writing program fails two times the file msvcr110.dll is missing?? what to do.
Also apache fails to install.

In fact I have three questions looks like.
Like to hear.
Kind regards,
ilioSS
