Domoticz

Can you try to just type in the IP of the ECU-R in your browser and see what it returns?
Webpage with navigation or maybe an error message?

When communication is done for Zigbee from converters to ECU-R can you not add them directly via a Zigbee controller?

Perhaps I should replace the ECU-R with a ECU-3 module? Does the ECU-3 support QS1 inverters?

I have been successful to pull the 5min timestamps from the EMA database into PVoutput, so I could load into Domoticz from PVoutput

I do have a zigbee stick in my Synology server, but so far it does not see the inverters.

Perhaps it is better to look a bit into the APsystems EMA web client to understand their API calls

Yes, my data is uploading to PVO by a python script (apstopvoutput.py) in crontab every 5 minutes. Is there a python script available that sets up the domoticz sensors etc. on which I could build (basically merging both scripts)?

Is there a custom solution for a virtual sensor to compute my power consumption per 5 minutes by adding the PVO value to my reported P1 energy consumption value (which is negative in case I produce more than I consume)?

The other device is PVO Solarmain, giving the produced energy of my PV panels per 5 minutes. I want to create perhaps two other virtual sensors: one: the consumed energy over 5 minutes (same interval) and another one combining both in the energy (per 5 min) consumed in my house.

        level = domoticz.LOG_DEBUG, -- change to domoticz.LOG_ERROR when all works OK
        marker = 'PVO - P1' ,

Why didn't we discussed that last year? By the way, does it still functioning, to your satisfaction?
Would Zigbee2MQTT be a good solution? See: https://www.zigbee2mqtt.io/.

The Micro-inverters of APSystems are not in the list of supported devices. I did not expect that, but they could be added.
If they are supported by Zigbee2MQTT, the ECU is not needed anymore and you are completely free from APSystems.
That would be an interesting option, at least for users of Home Automation Systems. What is your idea?
