And now it’s totally broken for me too… “Device unavailable,” and any attempt to repair just freezes right after authentication with singlekeyID.
There is a new experimental version now 3.2.75 wich adresses the issue of reconnection. Give it a try.
Tried the latest test version, 3.2.75. Updating to it didn’t help and still getting “device unavailable, could not get OAuth2Client.”
After uninstalling and reinstalling, and re-adding the device, the message changed to “device unavailable, Home appliance is offline.” Which is bs of course since device works just fine with the original app on my phone.
When I try to repair the device, it freezes right after returning from singlekeyID authentication. Looks like they completely broke something in the handshake or how authentication is passed.
Tried the new 3.2.78 test update, still no dice…
Had something similar, some time ago. When I checked in the android app settings, network, I saw that the triangle of the network devices was not complete green. So I had to fix this first. Second, when I remember right, it was better to setup the home connect app on pc than on the smartphone. More options were there, but I’m not sure.
For the the loose of the authentication some hours after reconnect, I setup a Flow as Workaround, with an automatic reconnect every 4 hours.
Hope this is helpful for anyone.
Tried the new test version, still no results. It keeps saying device is offline when trying to connect. Meanwhile it works flawlessly with the native Bosch app (so it is not offline…)
Yes
Ok. Have you tried to connect the homey app with your PC ? There is a checkbox you have to confirm, that Homey is allowed to connect to your Bosch One key account. With Home assistant I had to setup a developer account for the Home Connect Integration. Not sure if it was the same with homey, it has been to long ago.
Yes, and always has. The Homey app has never reflected this however. The problem, whatever it is, has nothing to do with local networks, it likely has all to do with Bosch-Siemens. I have had several reasons to contact their support and they are never useful
I see the “green triangle” in the network status too, but the washer/dryer is still “offline" in Homey.
Tried both from the mobile app and on desktop, no change.
Hi Viktor, I assume you see the device in homey but it is not ready to work.
Can you try to plug it off from power, wait some minutes an plug it in again.
I’m experiencing the same issue. I have version 3.2.67 installed, but the app is currently disabled while I wait for an update that actually works. I reached out to the developer via email a month ago and never received a response—this is disappointing customer service.
I purchased a Siemens washing machine and was planning to buy additional appliances like a refrigerator, freezer, and dryer. However, I will NOT choose Siemens/Bosch products in the future if they continue to ignore their customers.
Same here, really annoying. My Homey crashes if the bosch siemens app turns on the dishwasher. Every hour the dishwasher is disconnected. No reaction from the developer. Why does Athom approve this app??
Good question!
Why does Athom approve this app when it does not work?
If the developer doesn’t reply to the users concerns/problem, maybe they will answer if Athom ask them?
I’m currently making plans for a complete new kitchen. My plans are to buy all appliances from Siemens. But the more I read this topic the more I get my doubts.
Hi @Doekse, can you please help? Or maybe you have something to say about this matter?
Thanks in advance
As you can see in the changelog, the app is actively maintained, with the latest update released just three days ago. I’ve already notified the developer and, as the changelog shows, it’s being worked on ![]()
When this app is labeled as ‘official,’ I naturally expect it to function properly. It has now been seven weeks since I reported the issue to the developer, and I still have not received a response. Perhaps my expectations for the app are too high.
As Doekse mentioned, the app is still under development, and they are attempting to fix “certain issues”. However, during these seven weeks, approximately eleven test versions have been released, which, according to users, do not resolve the problem. I still consider this to be inadequate.
It is somewhat disappointing for the Siemens brand, which has otherwise served me well. I had set a requirement that any new appliances should be compatible with the smart home system. This time, I purchased a Siemens washing machine, but due to the lack of support for my smart home system, I will be receiving a Miele dryer next week. Next year, the refrigerator and freezer will be replaced after fifteen years of service, and those will most likely be Miele as well
If the developer was reacting on emails they could have used maybe some extra information on what is working or not and then make a app that is working again like 7 or 8 weeks ago.
It was working fine for ages and after a update it is useless. Before it only needed 1 restart of the app at night and it was working.
But i hope it is working soon.
I hit the breaking point and went full monty, started from scratch.
A parallel thread gave me the final push: Bosch-Siemens Home Connect is not working after some days - #19 by Heszi
Deleted the Bosch app from Homey, removed the Homey from connected apps and services in the Bosch home connect app, removed the washer/dryer from it, then reset the machine to factory settings.
Then I re-registered everything, installed the latest test version of the bosch app on Homey, added the device.
The machine showed up online and notifications started coming through just fine after a test run.
Now it’s just a matter of seeing how long it lasts…
I’ll keep you guys posted, though I wouldn’t hold my breath.
