External integration - hOn (Haier, Candy, Hoover)

[Will_71]

Hello everyone,

A bit late as it was published this morning

For those who have a Haier, Candy or Hoover device connected to the hOn app (washing machine, dishwasher, air conditioning, fridge…), here is an external integration that brings it into Gladys.

GitHub - William-De71/gladys-hon: Haier, Candy and Hoover appliances of the hOn app:...

What it does

It connects to the hOn cloud with the app’s email and password (cloud transport: data passes through Haier’s servers), reads the status of the devices every minute by default and sends your commands. Gladys does not have a native hOn integration; for other washing machines, see the thread Implementing Washing Machine Tracking.

Features

• Washing machines, dryers, dishwashers: status, phase, program (choose to launch), remaining time, pause, door, consumables, salt and rinse aid.
• Air conditioners: on/off, mode, setpoint, ventilation, oscillation, temperatures.
• Fridges, freezers, wine cellars: temperatures and setpoints per zone, doors, modes. Ovens: read-only.
• 7 scene triggers: cycle started, cycle finished (with duration), error, refill needed, device disconnected/reconnected, account refused.
• 3 scene actions: start a program (with delayed start), pause/resume/stop, read status.
• 2 widgets: “hOn Devices” and “hOn Device” (cycle progress, buttons).

Scene examples:

• when the washing machine cycle is finished → send “The laundry is ready” to the family;
• when the dishwasher is out of salt → notify me;
• on weekdays at 1:00 PM, during off-peak hours → start eco_40_60 on the washing machine loaded in the morning.

Installation

• From the store: search for “hOn”. Available within the day, pending indexing.
• Or from the repository URL: https://github.com/William-De71/gladys-hon.

Minimum version of Gladys: 5.1.1.

1. Enter the hOn email and password, save, “Test connection”.
2. Discovery tab: add your devices.
3. To start a program, enable remote control on the device.

Known limitations

• Haier does not publish an API: I ported the pyhon-revived library to JavaScript, which is used by the Home Assistant integration. Haier changed its connection in June 2026 and may do so again.
• I couldn’t test with a real hOn account, only with anonymized data from real devices published by the pyhOn project: your feedback is essential.
• The states are queried (no push yet). Accounts with email two-factor authentication are not supported.

Technical details

• One Gladys device per hOn device, identified by its MAC address; the features follow what the model reports.
• The session (never the password) is kept in /data: a restart does not reconnect, as hOn blocks accounts that connect too often. A refused connection pauses attempts (15 min, then more).
• A cycle started or stopped by a scene action does not trigger triggers (no loop); the first state read after a startup produces no event.
• Cloud badge per device, unreachable when it is no longer connected to hOn.
• The program names are those of the hOn cloud, in English; the “List programs” button gives those of the “Start program” action.
• The fridge modes (super cold…) remain read-only if the model does not expose them in its settings.

Provide feedback

Via a GitHub issue (Issues · William-De71/gladys-hon · GitHub) or by replying here, with the version of Gladys, the version of the integration, the type and model of the device, and the logs with DEBUG=gladys-integration-sdk (without email or password).

Thanks to the authors of pyhOn / pyhon-revived.

Tested with a fridge and no issues detected!

[Will_71]

Thanks for the feedback. I didn’t even have time to test it myself on my washing machine.

Good evening @Will_71

Thanks for this integration

Here is my fridge dashboard:

I’m jealous of @GBoulvin’s display, which directly shows the temperatures on the widget

We can display the current mode (by the way, mine is currently in « eco » mode and not « auto »), but not select it: a dropdown list would be better, right?

The « h0n » app offers to add or display the contents of the fridge. Should this also be proposed?

Have a nice evening,

Jean

[Will_71]

I can’t tell you right now, I’ll check and let you know.

[Will_71]

@jean_bruder I need to delve deeper into the subject, but in the meantime, can you send me the content of the Logs tab after a « Refresh »? That will at least confirm that the fridge is being read, pending a new version with more in-depth diagnostics.

[Will_71]

@jean_bruder, you can update now, I’ve added diagnostics, I’ll have more details to diagnose your fridge

[jean_bruder]

Hi @Will_71

I just updated, the container started fine, but…

And then:

Tell me how I can help?

Have a great day,

Jean

[Will_71]

I’m watching tonight.

Good evening @Will_71

After uninstalling/reinstalling, reconnecting, and adding the refrigerator:

Thank you so much

By the way, I have a question: I just « played » with a scene that should turn the kitchen light on/off (located on the countertop, next to the refrigerator) when opening/closing the door. However, this only works alternately (either not at all, or with a delay…). Can such a trigger be used properly?

Have a nice evening,

Jean

[Will_71]

Thanks for your feedback. So everything works now?

As for the trigger, good question, since it’s not live but through the Cloud, yes, you can have some delay.

[jean_bruder]

Hello @Will_71

I confirm that I have access to my refrigerator Now, as mentioned earlier, I will try to use the door as a mood trigger

Have a great day,

Jean

[Will_71]

ok let me know if it’s really too slow with the triggers and I’ll see if I can do something
Have a good day

Small issue for a few days: The cloud hOn is not responding (hOn /unified-api/v1/view/appliance-list: HTTP 403): will retry at the next query.

Have they changed their API?

[Will_71]

Thanks for the feedback.
Nothing indicates an API change on hOn’s side (other hOn libraries work with the same parameters).
I think hOn invalidated your session and the integration did not make a real connection in this case.
I am publishing a version that reconnects; in the meantime, uninstalling and then reinstalling the integration (like Jean above) should start a new session.
If the 403 error returns after the update, the error message will display hOn’s response: copy it here.

Fixed in 0.3.1! Thanks!
