Hi jeanmarc,

After I come home, I try and tell you what happens
Thanks again.

Hi jeanmarc,

this is the error:

"PHP Fatal error: Call to undefined function curl_init() in /var/www/123solar/scripts/protocols/fronius.php on line 14"

You need to enable Json, Calendar and Curl extensions in php.ini, it's mandatory to run 123s or meterN.
Edit /etc/php/php.ini and uncomment extension=calendar.so extension=curl.so
Then you may need restart the PHP service.

Hi jeanmarc,

I reinstalled php5 "sudo apt-get install php5-curl", and this is the answer of the test comunication:

Communication is ok !

Arrays
I1V : 352.5 I1A : 1.4 I1P : 493.5
I2V : I2A : I2P :
I3V : I3A : I3P :
I4V : I4A : I4P :
Grid
G1V : 232.6 G1A : 2.23 G1P : 462
G2V : G2A : G2P :
G3V : G3A : G3P :
Inverter
FRQ : 49.96 EFF : 93.62 INVT : BOOT : KWHT : 1149.817

but 123solar don't start, the botton on the admin page remains OFF

Metern is ok

Thanks

enable debug in main configuration, then start 123s and check the errors log in debugger

Hi jeanmarc,

yes, it's running all

Thanks very very much

Now I try to load the historical data, downloading them from the inverter

[jeanmarc]

Neat Is the pooling refreshing time fast ? The local network load isn't too busy with the requests ?

Hi jeanmarc,

Is the pooling refreshing time fast ?

yes, I think so.

The local network load isn't too busy with the requests ?

it does not seem to me, but there is a system to understand that
