IndexError: list index out of range

[JohnnyPicnic]

When toggling the query switch I get an error "IndexError: list index out of range" It looks like the main ECU updates but the individual inverters are not updating. There are three separate errors:

Are you using the latest beta version? If you are not, please try: https://github.com/ksheumaker/homeassistant-apsystems_ecur#beta-program If you do use the latest beta release and it does not solve the issue, please provide some info about your ECU type, inverters and a piece of logging by removing the first # in line 131 and 135 from sensor.py (note the indent and restart HA after editting)

[JohnnyPicnic]

Yes I switched to the beta so I'm running v1.2.15. It does seem to be working better than the main version but I'm still getting the index out of range error.

Firmware: ECU_R_1.2.22 Inverters are YC600

home-assistant.log

[HAEdwin]

Thank you, you can stop the logging again. For my understanding and impact, for what purpose do you use the switch? With your ECU-R there is no need to stop querying when the inverters are offline. In my case I leave it querying 24/7.

[JohnnyPicnic]

When I first loaded the integration I was using the main version and although it loaded and populated all the sensors, the inverter data would not updated. So I thought it was related to the query switch. Now I see I don't need to use the switch. Thanks!
