GoodWe loses connection in the early morning

[LarsMichelsen]

The problem

I have been using a GW15K-ET for a few weeks now. I have integrated the device via WLAN stick and connected it to my home automation via Homeassistant. The whole thing was quite easy to setup and works quite well most of the time.
However, I have observed a rather fundamental problem since the beginning:

Every morning all values disappear from Homeassistant and the device device does not provide any information via WLAN anymore.

First I tried to solve the issue by resetting the WLAN stick, which sometimes seemed to fix the issue after a few minutes, but most of the times it did not help. Completely switching off the inverter and let it restart helped most of the times.

Now I observed that I can recover the situation way better by disabling the integration for a few minutes and enabling it then again. This constantly recovers the situation every day.

Anyone else with similar observations?

To gather more information, I have set up a ping monitoring in Home assistant. Every morning I can observe a pattern like you can see in the screenshot: The device is several times briefly not connected reachable via WLAN to then come shortly after again again. I don't understand yet what triggers this. Anyone have any ideas?

I suspect that something is out of step with these repeated connection attempts. Maybe the connection between the inverter and the WLAN module. I keep researching in this direction.

However, I think the integration should be able to recover any temporary network connection issue. Looking at the logs I recognized there is something like this, but it seems it does not help in my situation.

To get more data from the integration, I enabled the debug logging and see the same pattern every day, like you can see here:

It goes then on like this for hours.

But when I disable the integration and enable it again after a few minutes, it recovers. Then the
log looks like this:

07:12:30 Disable integration
07:15:08 Enable integration again

Another interesting observation: If I switch off the strings at the hardware switch of the inverter in the evening, this does not happen. As if the WR tries to do something at the first light. As long as the light is not sufficient, the attempt is aborted.

Do you think it might be worth to build a slow down in the recovery logic into the integration? Something like: After 10 tries failed, wait for X minutes to reconnect.

[mletenay]

The trouble is that there is nothing to "reconnect".
The inverter communicates via UDP so there is no session to reconnect and every request is independent communication.

[LarsMichelsen]

Thanks for your fast response 🥇

Understood. From the HA integration perspective we use UDP, and do continuous polling with the WLAN module of the inverter. However, to me it seems there is an internal state somewhere, which might be between the inverter and the WLAN module, because it helps to stop polling for some time and retry after a few minutes.

[LarsMichelsen]

Just wanted to let you know that I found a workaround for me in the meantime.

I added https://github.com/frenck/spook to my HA instance and now use this automation to automatically detect and recover the situation by restarting the integration. I still have a short downtime in the early morning, but that is not a big issue to me.

If it's not only me, it might still be worth fixing this issue. But until someone else complains, we could also leave it as is.

[danriedl]

I do confirm, that I have the same exact issue @LarsMichelsen .

[Onandon11]

+1 got same issue, created an automation for it which force reconnects it to my WiFi AP and then reload the integration.

[XanderF]

I had the same issue as well. Each morning home assistant could not connect to my GoodWe inverter. However the issue wasn't caused by the integration but it was network related. My Unifi AP's were optimizing channels at 3 AM and BSS transition was enabled. Turning those options off (for the SSID the inverter used) fixed the issue.

I’m also using Unifi AP’s, but I disabled channel optimization because I tweaked it manually. What I’m trying to say; is the BSS option guilty of the inverter connection then?

Yes I think so. Disable BSS for IoT devices that do not change position. Like inverters, temp sensors, etc.

I tried.. but no success. Still haveing random disconnects, mainly in the morning, but sometimes also couple of times during the day. I’m now looking into the Channel, also because the Inverter itself sends on fixed Channel 6. Don’t know why it should be a problem but I’m just trying…

[Onandon11]

Still no success... The image below shows an indication about the during-the-day behavior. Every gap in the line is the automation kicking in because the sensors go to unavailable for more than 10 minutes.

I even further decreased the polling frequency maybe that's causing the glitch (although I don't understand how you can "overload" and UDP stream, because the messages just come...)

[Onandon11]

Maybe it will help someone else, but I think I found a solution to the problem, or at least a workable solution.

I created a separate SSID for the inverter to connect to and I’m now running for 48 hours straight without any connection problems - also not in the morning.

I’m not sure what the problem is, but maybe it has to do something with the meshing op the AP’s which the inverter doesn’t like.
