Home Connect Direct Binding (no cloud)

[holger_hees]

for me, home connect direct works without any issues.

I tested it with a washer, a dishwasher and a coffeemachine.

[jb4711 (Jonas)]

Are there any errors in the log?

[florian-h05 (Florian H.)]

No, I traced it back down to a network issue. Cutting power for a few minutes for the dishwasher solved the issue.

[jb4711 (Jonas)]

That’s great. I was starting to get worried.

I also had some network issues at one point. I have a lot of separate networks, like smarthome_untrusted. Unfortunately, communication between the networks wasn’t working. Luckily, it’s been stable for a while now. Back then, I had to restart the access point, and it started working again.

[jb4711 (Jonas)]

Maybe this will be of interest to some of you. I turned my “old” dryer into a smart appliance.

Bosch and Siemens appliances smart without Home Connect: reading the internal D-Bus over MQTT

No cloud, no account, no power-consumption guessing: the machine already says what it is doing on a service bus behind the front panel. This is the firmware I wrote for an existing interface board, building on the reverse-engineering work of others, and the openHAB configuration behind it. Where the idea came from On holiday I watched the 39C3 talk Hacking washing machines by Severin von Wnuck-Lipski and Hajo Noerenberg, and I thought the idea was brilliant. B/S/H appliances (Bosch, Siemens, Ne…

Hi everyone, I just released a new beta version of the Home Connect Profile Downloader. I’d love it if a few of you could give it a try and test it out.

I completely rewrote the whole app from scratch. The UI is much cleaner now and handles errors far better. On top of that, the app size is down to just 4–7 MB. It supports Windows, macOS, and Linux (both x86 and ARM).

@jb4711 Thank you for the updated profile downloader Keeping it alive is important!
Speaking of which, I found something interesting in my dryer. The lint filter and condensate full status aren’t working…
In the event list I see them:

{
      "uid": 17666,
      "key": "LaundryCare.Dryer.Event.LintFilterFull",
      "contentType": "ENUMERATION",
      "dataType": "UINT8",
      "handling": "NONE",
      "level": "ALERT",
      "enumerationType": 1,
      "enumerationTypeKey": "BSH.Common.EnumType.EventPresentState"
    },

{
      "uid": 17665,
      "key": "LaundryCare.Dryer.Event.CondensateContainerFull",
      "contentType": "ENUMERATION",
      "dataType": "UINT8",
      "handling": "NONE",
      "level": "ALERT",
      "enumerationType": 1,
      "enumerationTypeKey": "BSH.Common.EnumType.EventPresentState"
    },

I assumed this meant that the capabilities exist.

But when I turn on the dryer the output of /ro/allMandatoryValues
is always off for:
LaundryCare.Dryer.Event.CondensateContainerFull
LaundryCare.Dryer.Event.DryerSelfCleaning.CleanLintFilter
LaundryCare.Dryer.Event.CondensateContainerFull

But the interesting part is that I’m getting updates in the home connect app to clean the lint filter and empty the condensate tray… so … Do you have any insight?

[jb4711 (Jonas)]

Hi @Pedro_Liberal, can you see any events published under the resource /ro/values? I think for "level": 'ALERT', it’s normal for it to be a stateless value. It only fires when an alert occurs.

In openHAB, you would set it as a trigger type.

[Pedro_Liberal]

/ro/values? I see some, yes.

but not the lint or condensate.. And now I’m super confused because the home connect app stopped showing the Lint warning without anyone touching it… what the heck..

You mentioned a trigger? I’m using the switch enum mapping, is it wrong?

[jb4711 (Jonas)]

You have two options for solving this. Either leave it as is and create a rule in OH that reacts to “ON” and performs an action. Or you can use “Trigger” as the type, but then you’ll need to compare the string values in the OH rule.

These alert channels are only set to “Present” for a very short time. For example, I always send myself a push notification to my smartphone whenever it switches to “ON.”

[Pedro_Liberal]

I may be misunderstanding something then. Let me see if I can explain my reasoning and maybe you can recognize where I’m going wrong.
So I have the switches created at the channel level right?

      condensate-container-full:
        type: enum-switch
        label: Condensate Container Full
        config:
          valueKey: LaundryCare.Dryer.Event.CondensateContainerFull
          onValue: "Present,Confirmed"
      lint-filter-full:
        type: enum-switch
        label: Lint Filter Full
        config:
          valueKey: LaundryCare.Dryer.Event.LintFilterFull
          onValue: "Present,Confirmed"
      clean-lint-filter:
        type: enum-switch
        label: Clean Lint Filter
        config:
          valueKey: LaundryCare.Dryer.Event.DryerSelfCleaning.CleanLintFilter
          onValue: "Present,Confirmed"

So even if they change state (off / on / present whatever) I would expect to see that in the analysis menu inside of the item linked to the channel, even if only for a split second, no?

I don’t see even a sliver anywhere. Is my understanding fundamentally flawed somewhere?

[jb4711 (Jonas)]

No, it’s exactly as you described it, that’s correct. That’s exactly what I would expect. It’s strange that the event never happens. Is there perhaps another event that corresponds to it? The next time the notification appears in the Home Connect app, you should write down the time and compare it with the binding logs in the UI.

[Pedro_Liberal]

@jb4711 thank you for that tip! Got to work on the dryer, and found out that there’s one more!
LaundryCare.Dryer.Event.DryerSelfCleaning.CleanSelfCleaningModule

This one is for the dryers with the self cleaning condensers, no wonder the others weren’t working. Got it to work just now
