Fronius integration timeouts with inverter #61783

Closed Gollam closed 2 years ago

Gollam commented 2 years ago

The problem

Since I switched to the refactored fronius integration, quite frequently a lot of the data becomes 'unavailable'. This wasn't happening with the older integration code, I guess it is now more sensitive to errors. I discovered that when this is happening, the inverter api returns some kind of error response like on this pic:

And I think this transfer timeout is the reason for the entities becoming unavailable. Now my question is, are these transfer timeouts normal, or do they indicate a problem with the inverter firmware maybe? I don't know if these transfer timeouts happened all the time before, our inverter is around 1 years old.

What version of Home Assistant Core has the issue?

core-2021.12.1

What was the last working version of Home Assistant Core?

core-2021.11.4

What type of installation are you running?

Home Assistant Container

Anything in the logs that might be useful for us?

These are quite frequent since the update:

Error fetching fronius_power_flow_http://192.168.0.102 data: Connection to Fronius device failed at http://192.168.0.102/solar_api/v1/GetPowerFlowRealtimeData.fcgi.

Hey there @nielstron, @farmio, mind taking a look at this issue as it has been labeled with an integration (fronius) you are listed as a code owner for? Thanks! (message by CodeOwnersMention)

Hi 👋! Thank you for raising this issue! It seems that the internal connection of the Datalogger and the inverter (I assume you run a Symo or Primo) is kind of unstable. I just ran some tests: 8 out of 1000 requests raised Code: 8 - LNRequestTimeout. Reason: Transfer timeout.. I guess we should catch that directly and just try again before setting the entity to unavailable.

Can you confirm that this only happens to the fronius_inverter_1_http://<host> endpoint? My setup also queries power_flow and meters, but only inverterseem to raise this error.

Gollam commented 2 years ago

Sadly we do not have smart meter installed, so I cannot tell :/

farmio commented 2 years ago

You still have logger and power_flow - do these raise any unexpected issues or do all begin with fronius_inverter_1_? Especially power_flow is queried 6 times more often than the inverter endpoint but doesn't error on my system 🤔

Gollam commented 2 years ago

I also have this kind of logs:

Error fetching fronius_power_flow_http://192.168.0.102 data: Connection to Fronius device failed at http://192.168.0.102/solar_api/v1/GetPowerFlowRealtimeData.fcgi. 2021-12-14 07:59:29 ERROR (MainThread)

I cannot see any error logs starting with logger.

farmio commented 2 years ago

Oh, I see you wrote this in the original issue description too. Are there as many occasions as for the inverter error (BadStatusError), or just a few? This will also happen when your inverter powers off when not producing (eg. sunset - if it is setup to do so).

Gollam commented 2 years ago

Okay, I collected all errors from today.

Actually now I see there were 2 logger issues.

Also I have

Loading Fronius via platform setup is deprecated. Please remove it from your yaml configuration

But I guess this is not related to the problems.

farmio commented 2 years ago

Oh dear... is your inverter connected via flaky Wifi?

Gollam commented 2 years ago

It is strange, because the router is right next to it, and everything else has stable connection. Although I upgraded datamanager's fw a few days ago. I pinged it during the day, most of the pings were under 100 ms, but sometimes 1-2 went with a higher delay.

farmio commented 2 years ago

Fronius Wifi is not particularly known for its stability. Maybe try to connect it via cable.
