I use Pass2PHP ;-0

Code: Select all


        $input = ($s['Electra']);
        $meter = explode(";",$input);
And dump the data straight into influxdb.

If you would use Pass2Php the function could looks like:

Code: Select all

function influxdb($device,$value)
    if (strpos($device, " ") !== false) { $device=str_replace(" ","_",$device); }
   $postdata = ("device_$device value=$value ".system('date +%s%N'));
//   lg('InluxDB Data: '.$postdata);

    $opts = array('http' =>
            'method'  => 'POST',
            'header'  => 'Content-Type:application/octet-stream',
            'content' => $postdata

    $context  = stream_context_create($opts);
    $result = file_get_contents('http://192.*.*.*:8086/write?db=domoticz', false, $context);
hi mate,
long time no see :p
just wondering if you have an 'updated' version of your influx program in php?
I want to use it also, i was writing something myself, but why writing something on my own, when there is already something existing :p
Indeed indeed
You know how to reach me my friend ;-)
Actually the current setup as shown above has been working ever since. I'm totally happy with it. Something not working for you correctly?
I moved my influxdb to a spare machine and have grafana in a docker on a synology for representing the data. So the domoticz machine is not under a lot of stress..
Using Pass2php since 2016-12

My repy is a bit late so hopefully you found a solution already but on my system (similar setup with RPi3, influx and Monit), I started having issues with Monit restarting domoticz regularly and unresponsive web ui too. It always seemed to coincide with the automatic backup that domoticz was doing of the database (every hours). It got worst after installing influx and I guess it's related to influx producing a lot of read and/or write on the SD card at the same time and thus making the backup of the DB longer (only a guess I can be completely wrong).
I recently bought a PiDrive (hard drive for RPi) to replace my SD card and it improved quite a lot the situation (1 or 2 monit reboot in the past couple of month at most instead of once a week maybe before). I think this is due to the hard drive having faster access time than the SD card I was using before.
I ended up moving influxdb to another RPi that I already had for another purpose. So basically never got to the bottom of this but things went back to normal after the move...:)
