Hi,
after the firmware of Fronius inverter have been updated, 4 days ago, the plugin stopped working.
The problem is on some parameters that now are "null", like P_Grid, P_Load, ErrorCode, LEDColor, ....
This is the string passed from the inverter, as logged by your plugin.
Thanks a lot for your great work!!

HI,

I have a fronius TL4.0 inverter with a datalogger unit. I discoverd the messages from the datalogger unit can be retreived with:
<IP>/solar_api/GetInverterRealtimeData.cgi?Scope=System
So I replaced this line in plugin.py, however I get thes errors:

__

Maybe I need another plugin for python? Or is the data structure incompatible? This is what the datalogger sends to me.

Hello,

It's not obvious that one will have only one inverted at 1 adders.
According to documentation DeviceId could be in range from 0 to 99 thus assuming address '1' could lead to potential problems.

My suggestion is to Parse Scope=System request's answer and check how many (and with what addresses) devices there are in the system.
Based on that create devices with proper index.

BR,

I'm using this plugin a while now and it works great. I have an issue with a negative peak in daily generated energy graph, witch is reccurring every day at the same time. This negative value changes the scale of the graph, and I'm not shure if this affects also the calculated value.

I just installed this plugin from git to Domoticz V2020.2 and it's giving me the following errors into the log:

Hello, I installed this plugin, then configured it like on the screen
I've got Fronius Symo 6.0-3-M

When I hit enabled and apply - then domoticz stops working - hardware table is empty, when open devices it says loading in endless loop, other tab like temperature utility etc is empty.

Where Can I find logs of this plugin?
Is there something that could I miss? additional library?

IP is corect - I can reach fronius via browser

To get domoticz working again, need to disable FroniusHttp
sudo sqlite3 -header -list domoticz.db "UPDATE Hardware set Enabled = 0 where ID = 6"
then restart domoticz

Hello!
It would be interesting to be able to see in real time the load on the strings, voltage, current from which the power produced results. I noticed that there are API commands that can query to get this data for the two strings of the inverter.
"solar_api/v1/GetStringRealtimeData.cgi"
I would be very happy if you could also implement this information in this plugin.
Thank you!

Hello,

Can you tell me what's this data mean ?

Hello,

I haven't an AKU, but I'm really interested about having data from the grid or from my solar panel in live... Because from type Fronius instead of Fronius AKU

we haven't those data...

But even I choose it, my data stay to 0. Any idea why ?
