Can not connect to ECU. Check log

[dclobato]

After upgrading HA and the integration, I'm getting an error when I try to add my ECU.

After click on "Add Integration", select "APSystems PV solar ECU" and inform the IP address of the WiFi interface, I get a "Can not connect to the ECU" error message. I tried twice, and same error on both...

Below, the log:

2022-02-21 21:14:37 ERROR (MainThread) [custom_components.apsystems_ecur.config_flow] APSystemsInvalidData exception: Error getting checksum int from 'Inverter data' data=b''

    checksum = int(data[5:9])

During handling of the above exception, another exception occurred:

My ECU is on version 2.0.5017 (I think)

Same problem here sinds today

If you both are using an ECU_R_PRO with firmware 2.0.x, you might be running into same kind of issue as reported in #42

You could follow the suggestions in that issue to get integration working.

Yeah! It's working again! 🥇
