Hullo!

My inverter is showing the correct model now. Thank you.

I've noticed occasionally the inverter will report UNAVAILABLE on all sensors.

The Logs show the following: Any ideas? Both HA and the Inverter Ping with no latency difference during these periods. Would I be better to increase the time between the polling intervals? I'm on 45s presently.

Yes, that seems to be ok, but I get the Unavailable issues whilst the sun is up - EG, i'm receiving ~4000w at present, and it went Unavailable for a cycle.

[alexdelprete]

Sorry, I thought the inverter was offline, but I see it's 9am over there.

No, it's not normal. Turn on debug logging on the integration, wait 2-3 minutes, then check the full HA logs, search for "abb" so you see only linea related to the integration. Post the log here.

Actually, this log set may be better.

As you can see from the below snippet (see the check_port lines), port 502 on that IP was not available at socket level: I do a check port before connecting, and this means there's something not right at network level. How's the wifi signal of the VSN card? How's the RPi connected, Wifi or ETH?

Also, this is not a very nice error: RPi already give a lot of weird issues, if you don't power it correctly, it's even worse.

[homeassistant.components.rpi_power.binary_sensor] Under-voltage was detected. Consider getting a uninterruptible power supply for your Raspberry Pi.

Signal strenth looks ok. UniFi is reporting no drops, and the inverter's interface reports Strong.
I've got a new legit RPI PSU being recieved today. I saw those popping up in the last week too.

[alexdelprete]

I see this, what does it mean? Poor is not a good indicator...

[lucasdaly90]

I think I'll look into the Ethernet module, they seem cheap and that will take any RF issues out of the equation.

Pi is Ethernet, Inverter is Wifi - the AP is about 4m away in direct line of sight.

[alexdelprete]

The undervoltage is an issue too, RPi is very power sensitive. Fix all the issues and you won't have the connection problems.

[lucasdaly90]

I'm somewhat ressurecting this thread. I'm constantly getting unavailable for requests from this inverter. I've replaced PSU etc, and that seems to be rock solid now.

the log doesn't say anything, enable debug in the integration and restart.

once you have the debug log I can see what's happening.
