Wolf SmartSet Service - Error fetching wolflink data: Error communicating with API

[Andes1984]

The problem

I've been using the integration since September without any issues. Starting about 1 week ago, the sensors are getting unavailable more and more often during the day, coming back to normal without me changing or restarting anything.

I have a Wolf CHA-10, communicating through a ISM7 (Wolf Link Home) which is connected via WiFi. The network connection is stable all the time (checking with a watchdog).

During the unavailable times:

• the local web interface of ISM7 is accessible and doesn't report errors, e.g. with the eBus connection of the IDU
• all values of the system are accessible using the smartphone app or the cloud interface (https://wolf-smartset.com)

Having the debug mode of the integration activated, these log entries occur when the sensors become unavailable:

2023-11-27 15:53:56.946 ERROR (MainThread) [homeassistant.components.wolflink] Error fetching wolflink data: Error communicating with API:

And sometimes after a few minutes:

2023-11-27 15:57:17.721 DEBUG (MainThread) [homeassistant.components.wolflink] Finished fetching wolflink data in 6.713 seconds (success: False)

Same here since yesterday.

[e0909]

While the sensors was unavailable Ive tried to login to the Wolf-Service via the mobile app. The login took more then 30 seconds - this worked in the past faster. So I believe its more an issue on the Wolf-Service side. On the other side its maybe possible to increase the login-timeout in the integration?

[lefgrter]

Probably this is an issue from Wolf's side. The problem happened for the first time 3-4 days ago. In the begging the portal was down also as they were upgrading their server or something like that. After that interruptions started to occur more and more often. Hope they solve the issue soon.

[Andes1984]

Maybe it is a performance issue at Wolf, since by now more and more heat pumps have been installed, and are operating now, maybe the amount of users simply is too high for their servers. Here's a screenshot showing the outages pretty good. In fact, they Only occur between around 10am and 3pm everyday. In the other hours there's no outage at all.

[lefgrter]

For sure they did something with their server a few days ago, I know it, as a week ago I was setting up my second heat pump and I was in contact with a technician of their representative in Greece. He had difficulties to work remotely from the portal and he confirmed me that something was going on with upgrading or something like that on the server side. Who knows. Hope they fix it soon or we sill need to find a way to get the data locally directly from the system. BTW interruptions here in Greece occurred mostly between 12:00-16:00. Time deference

!:)

[Andes1984]

Now there seems to be a whole outage of the service at Wolf. I'm getting a 503 when trying to reach wolf-smartset.com:

[lefgrter]

For me it is working now. I had a minor outage of a couple of minutes only

[e0909]

Seems to be stable again.

[Andes1984]

As always in the evening 😉

[e0909]

Without any outage today. Ive seen the last error yesterday afternoon. May I was lucky and on the high-performance side of the cluster (-:

[lefgrter]

Greek time around 13:00 was the worst period for today. Tomorrow will be better r day.... I hope:)

[ottelo9]

On my side its actually working good. Wolf CGB-2-14 with ISM7 connected via Wifi.

[Timieh]

Here also no problems. Only some issues because of new internet provider.... Can't connect the linkhome again... what a pain on WiFi will probally get a ethernet cable trough the wall

[bobynator93]

I have using the integration since the beginning of January. Since yesterday evening, I have been experiencing the problem described above. Has anyone else noticed this?

[Andes1984]

@bobynator93: same here.

For me, the problems started about 9 p.m. German Time (UTC+1). One big outage for about 1 hour, and since then very much small outages, getting more and longer since about 7 a.m. this morning.

Additional information: yesterday and today, our local energy provider activated the so-called "EVU-Sperre" (energy lock for heat pumps) for the first time.

For those who don't know: in Germany, heat pumps must be registered with your local energy grid provider, and are equipped with a control receiver. Through the energy grid, the grid provider can shut down your heat pump for 2h maximum, 3 times a day maximum, in case that the grid stability is no longer provided due to weak grid parts and massive energy consumption. Since the usage of heat pumps has rapidly increased in the past 6-12 months in Germany, but the energy grids have not been optimized in the same period of time, this can happen more often now.

[Wank-ster]

Same here. Connection goes randomly On/Off. Pretty annoying if you have automations running based on these entities... Local connection would be awesome.

[ottelo9]

Same here, live in Germany!

[Timieh]

@adamkrol93 can you support? Let us know how we can help you

[Andes1984]

@Timieh I don't think that the code owner can help here. I suppose the issue is on Wolf's side again, as it was back in November/December.

[ottelo9]

Maybe problems on Wolf side ?

[Timieh]

@Timieh I don't think that the code owner can help here. I suppose the issue is on Wolf's side again, as it was back in November/December.

But the logging on the Wolf side on the online smartset portal looks fine ? So maybe some webscraping issue or some? (I don't have too much knowledge about this)

[Andes1984]

What does your logfiles say guys? When I opened the issue in November, the logs showed these entries:

2023-11-27 15:53:56.946 ERROR (MainThread) [homeassistant.components.wolflink] Error fetching wolflink data: Error communicating with API:

And sometimes after a few minutes:

2023-11-27 15:57:17.721 DEBUG (MainThread) [homeassistant.components.wolflink] Finished fetching wolflink data in 6.713 seconds (success: False)

I will have time later this evening to enable the debug mode of the integration and share my logs.

[Wank-ster]

@Andes1984

As already stated in some prevous post by someone the login in smartset portal with the app is possible but it takes a while... And this is noticeable quite clearly. Maybe the timeout within the integration is triggered too fast?

[Andes1984]

@Serafigos

Just checked it on my cellphone, log message seems to be the same here. You could be right, since "device is Offline" is definetely wrong, I can access the Wolf Link Home's own interface in my LAN when HA logs state this log message.

In this case: @adamkrol93, could you maybe have a look?

[ottelo9]

Today the connection is running fine.

[Timieh]

Sorry to misuse this part (offtopic: The installation formerly went perfectly fine on my other WiFi contract. With the new installation i'm unfornately not able to put some special characters in the SSID. So I need to to reconnect the Wolflink to my new WiFi again. The reception seems really bad when accesssing on AP mode to wolflink internaly and can't find my WiFi. WPS also no succes. Someone the golden idea? (Phone Wi-fi and signal strength tests looks like ok to perfect reception. )

[muhkuh666]

I encounter problems connecting to Wolf Smart Service since today!

[Andes1984]

Same here, a few days already

UPDATE Today the communication is working without problems ...

[franky1808]

And again: The same fault. No connection. No data. Anyone else?

[Andes1984]

Right now it's working but I also had some outages yesterday and during the night.

[travismarius]

Same here. Outages started yesterday. Today happening every hour with 5min no connection. Will now Restart the wolflink ism7e

[DieterChmod]

I have the same issue. Interestingly, after logging into the smartset portal, the issue disappeared for now. By the way. First login to the smartset portal did not work. It returned an error, that too many connections were established. Maybe that helps.

[ottelo9]

In my side no problems.

[cyhyryiys]

Can Not Connect smartset since 12.03.24. Can someone Tell me how to setze Holiday Modus in Dashboard, so it is possible to Ferien a time Range, for example 15.03-20.03.24? Thnx

[msgrt]

Is it possible that Wolf has limited the maximum request frequency and blocks the requesting IP if it is exceeded? If the connect from Home Assistant doesn't work, I can't access it via the browser and app either. As soon as I change the IP, access works again for 5-10 minutes, then nowhere again.

I think you are right. Parallel Access from another IP (via LTE) ist working. Also the https://www.wolf-smartset.com/ Webpage ist not loading anymore.

[DieterChmod]

An alternative would be using "Wolf iSM8i Ethernet-Schnittstellenmodul Open Source" and https://github.com/marcschmiedchen/home-assistant-wolf_ism8 in Home Assistant. This does not seem to require the Wolf cloud, however it's 200 € more. Maybe this component and the one for ism8 could be merged together.

[bobynator93]

Iam using this now. Works perfectly without cloud. https://github.com/b3nn0/hassio-addon-ism7mqtt

[Andes1984]

Does anyone know the differences between the products Wolf Link Home, Wolf Link Pro, Ism8i and Ism7?

If you use this you can’t use the Wolf app anymore. It is either or, not both in parallel. I tried it and also ran into some issues that for example „1x warmwasser“ can’t be triggered through HA - read only. So if you want to trigger or set anything remote you won’t be able to.

Also the entity „Betriebsart“ wasn’t available which is crucial to me.

Really annoying what’s happens right now and I can also confirm that access from HA is blocked but access through lte/webportal is possible.

[travismarius]

Thanks! That is much better, link stays local and exactly what i was searching. My tests to parallel use the Wolf iOS App with Wolf Cloud Credentials are working! But HomeAssistant is my Main Tool, so glad it is now working without Wolf Cloud.

How did you do the installation? Which Firmware is your ISM7?

Of course, it took me also time to get it working.

1. Go to Settings -> Add Ons and install "Mosquitto broker" and Start it
2. Go to Settings -> Integrations and install "MQTT" It will ask you if it should use the local "Mosquitto broker" Add-On - click Yes
3. Go to Settings -> Add Ons "Add On Store" (bottom right) -> Repository (Top Right) -> Add "https://github.com/b3nn0/hassio-addon-ism7mqtt" Repository
4. Add the "Ism7MQTT" Add-On and Configure it for your WOLFLINK (Name, IP, Password) -> Open the Add-On -> TAB "Configure"

When you start the Add-On Ism7MQTT it will configure all Entities for your WOLF.

My ISM7 is on FW 3.00

Thanks a lot for sharing! I really appreciate it! 🥇

wow, so much more options and information's!

Smartset App (Android) is working as well from the same Network and LTE.

[muhkuh666]

Mine is FW 1.60 I do not get it running

[Andes1984]

The ism7mqtt option sounds great, I will test that this evening!

In the meantime, I cannot connect to Wolf SmartSet Service integration anymore, from 11:00 am this morning (German Time) on I can see the following in my HomeAssistant logs:

I did not change my login credentials, furthermore I am able to login to wolf-smartset.com with my known credentials and I am able to use the Android app with these credentials. Very strange...
