It took me a while to get things working for me, as I’m no expert in scripting.

This script runs between sunrise – 30 min and sunset +30 min
After that it looks at the state of the converter, if it is running than it will retrieve data and update the sensors.
A long time ago, but thanks for your script.
I changed your script to dzVents. I also made the call to Fronius async so the Domoticz will not hang if Fronius Inverter is not reachable.

}
I also changed another few things but basically it is doing the same.
I'am not completely happy with the devicetype of the 3 energy devices. It is showing Watt instead of Wh as a unit. I think a custom sensor as device type is better.
I also used some user variables for the IP addresses. Debug is done a little bit different.

Hi, I also wanted to share my script which I improved to cover my expectations. It was initially found in the "photovoltaikforum". User Gerhard told me that he got great support here; so credit to Gerhard and thanks to all who helped him.
I have also added the Own consumption measurement. This is supposed to count just what I consume from self-production. Important for that sensor is that the energy is "computed" based on the power. I have added a side note on the sensor creation string.

Code: Select all

   local idx_VERBRAUCH = 71               -- idx of PowerMeter (Energy provider supply)
   local idx_EIGENVERBRAUCH = 69          -- idx of Eigenverbrauch (House consumption W and computed KWh)
   local idx_PEIGENVERBRAUCH = 70          -- idx of PEigenverbrauch (House consumption own consumed W and computed KWh)

as i was rebuilding my Domoticz from scratch, i rewatched my old post.
Thanks glsf91 for editing the script, to be more resource friendly.
On the old script, i never used the values UAC IAC UDC and IDC. so i commented them out of this script
Also added some more help on what sensors to create.
Hope this helps others.

Does this script still run after updating the Fronius Inverters?
I had some issues with openWB but they fixed it there ;-) However in Domoticz I need to adjust the script. Any idea how?
Thanks

There is a change in an url parameter.
I used before "DeviceID". It should be "DeviceId" now.

P.S. The script works. You had to remove the last line that was not from the script, but somehow found itself in the frame on the forum.
Question:
How to limit readings to 1 minute?

Thanks glsf91 for editing the script, to be more resource friendly.
On the old script, i never used the values UAC IAC UDC and IDC. so i commented them out of this script
Also added some more help on what sensors to create.
Hope this helps others.

Hi,

After (I think) a firmware update of the Fronius device, I get these errors:

This is the problem. Look at my post a few above yours. It is caused by a firmware update.
Search for DeviceID and change to DeviceId. It is in the url sended to Fronius inverter.

Wow Thanks! That solved it.

Had the device and installed and upadated in december, so did not think that would be relavent.

Thanks glsf91 for editing the script, to be more resource friendly.
On the old script, i never used the values UAC IAC UDC and IDC. so i commented them out of this script
Also added some more help on what sensors to create.
Hope this helps others.

        end

How would I set the "Fronius_Opbrengst" to 0 in the part after sunset/before sunrise?

Do something like this after "domoticz.log('Sunset in minutes: ' ..timeofday['SunsetInMinutes'] + 60, domoticz.LOG_DEBUG)":
-- set day energie to 0 at start of day
if (minutes_now == 5) then
domoticz.log('Set day energy to zero at start of day', domoticz.LOG_INFO)
domoticz.openURL('http://'..IPdomiticz..'/json.htm?type=command&param=udevice&idx='..idx_Fronius_Opbrengst..'&nvalue=0&svalue=0;0')
end
This will run at 00:05

HAd the bright idea to put it behind:

domoticz.log('Fronius inverter Offline because of SunSet', domoticz.LOG_INFO)
domoticz.openURL('http://'..IPdomiticz..'/json.htm?type=command&param=udevice&idx='..idx_Fronius_Opbrengst..'&nvalue=0&svalue=0;0')

Is there a way, to not override the last value? Or something like:

domoticz.openURL('http://'..IPdomiticz..'/json.htm?type=command&param=udevice&idx='..idx_Fronius_Opbrengst..'&nvalue=0&svalue=0;'..DAY_ENERGY)

Get the current value of day energie and use this as last value.
domoticz.devices('Fronius_Total_Energy').counterToday
All times are UTC+02:00
