Home Connect: alpha testers wanted

Hafthor_Hilmarsson_O · December 19, 2018, 1:55pm

Success with my Boch Dishwasher , at least it seams I can see it and status !

Kare_Seest_Rasmussen · December 23, 2018, 9:51pm

I have just got around to set up Home Connect.

Im connecting throug a NginX reverse proxy, and when doing so and setting the URI to https://ha.my-domain.dk:443/api/homeconnect I get this error when trying to link.

https://ha.my-domain.dk: works to get me to the dashboard so I guess its the right URI

{
error: “unauthorized_client”,
error_description: “client or redirection URI not authorized”,
state: “OCYBRd2YS9hUVBw9JdXsl866039bOl”
}

How do I link it behind a proxy?

Kindly

Kåre

Yes, in fact the on/off switch doesn’t seem to work for any of the devices so far. In the case of my dryer, when it’s off it’s disconnected and I can’t switch it on with the app either. But the power off works from the app, so this should be possible to be made to work. I added an issue (https://github.com/DavidMStraub/homeassistant-homeconnect/issues/10).

DavidMStraub · January 5, 2019, 8:49am

Sorry for the late reply. Can you please have a look at this issue and whether any of the solutions there work for you? I don’t think that the reverse proxy per se is a problem. Have you set the base_url in the config of the HTTP component? To quote from the Spotify component docs (where the auth code is borrowed from):

You will likely also need to set the base_url attribute of the HTTP Component. This should be set using the same base URL as the redirect URI, e.g., if you used a domain name (not local IP) in the redirect, then use the same domain name in your base_url .

So I understood correctly that to test this I need to set up ssh like this?

DavidMStraub · January 6, 2019, 1:37pm

You mean, SSL, right? Yes, the API does not accept non-SSL redirect URIs. Your HA does not have to be accessible from remote though, so a self-signed certificate and a local IP/host (if that is what you set as base_url) should work.

Morrandir · January 6, 2019, 2:01pm

Yep, I meant SSL of course. I’ll give it a try. Thanks!

Where can I find documentation on how to use the component?

The following error appears in the log:

ltjessem · February 1, 2019, 8:40am

The warnings are normal for the custom component. As for the errors, I’m not sure why they appear, but for what it’s worth I get the same ones despite the component working flawlessly. The first comments in this thread address it but nothing has been done about it as of yet.

DavidMStraub · February 1, 2019, 8:55am

Sorry, at the moment the only documentation is the Readme of the Github repo, the Github issues, and this thread. I should really start to put together a PR to get this component into HA now that so many of you have tested it (Thanks!). Before doing this, I will also make sure to remove any unnecessary erros in the log.

zufferli · February 12, 2019, 4:35pm

Hi everyone,
thank you for your work, at home I have 1 dishwasher and 2 ovens, I am testing the code and I found the following problem:

The Switch Button Power state doesn’t work
I’m not a developer but saw on the init.py that you create the power switch from this code (I think) :
def get_program_switches(self):
programs = self.get_programs_available()
return [{‘device’: self,
‘program_name’: p[‘name’]} for p in programs]

I tried with Postam and maybe is better to get the information (power state) with this call:
GET “/api/homeappliances/{haid}/settings/BSH.Common.Setting.PowerState”
The value are BSH.Common.EnumType.PowerState.On
Following return value in postman:
“data”: {
“key”: “BSH.Common.Setting.PowerState”,
“value”: “BSH.Common.EnumType.PowerState.On”,
“type”: “BSH.Common.EnumType.PowerState”,

Is it possible to create more sensor or switch just to have more information about the appliance?

LIttle Guide to implement Home Assistant Home Connect

First you need to active SSL following this guide:
https://www.home-assistant.io/addons/duckdns/
Download APP HomeConnect on your smartphone and create your account and connect your appliance (Oven, Dishwasher, ecc…)
Create an account to https://developer.home-connect.com
Register New Application

new_application995×772 41.4 KB

Copy the contents of custom_components to the custom_components directory of your Home Assistant configuration directory from https://github.com/DavidMStraub/homeassistant-homeconnect
Add the following to your configuration.yaml:
Restart Home Assistant
On your home Assistant Click on the corner right

1844×133 23.7 KB
Click Configure for the configurator Home Connect
Click on Link Home Connect account
After that will be open a browser and ask you credential of your account Home Connect (not developer)
Approve appliance to be use on home assistant
If everything right you will be find new sensor, switch and binary sensor.

DavidMStraub · February 21, 2019, 8:59am

@zufferli thanks a lot for the detailed explanation and thanks for the API responses - this is extremely useful. The problem with using all these GET endpoints to query the state of the appliance is that they have quite severe rate limits and it does not seem realistic to have the entities update often enough if one needs to poll the servers. Indeed the write in the docs that one should listen to the event stream instead. So what I do at the moment is to simply listen to the event stream, but I am not sure whether all of the information that you obtained with GET also shows up there.

Concerning the sensors like CurrentCavityTemperature etc., yes these could indeed be implemented fairly easily, assuming their state is updated in the event stream. Could you find out whether this is the case?

What is indeed complicated are program configuration options. I am not sure how/whether this can be implemented in a convenient way in HA. Maybe the best thing would be to at some point introduce service calls with options, so people can write automations to trigger very specific programs on their appliances.

zsolt.kazda · March 2, 2019, 10:29pm

Hi everyone!

when I click the “Link Home Connect account” the url contains the internal address of my Home Assistant server. After when I replace the internall address to public domain name I can linked it, but when I want Approve it, the following error message appear: 500 Internal Server Error
Server got itself in trouble
How can I solved this problem?

zsolt.kazda · March 2, 2019, 10:55pm

Ok, I found the solution. I add Redirect URI #2 (on the https://developer.home-connect.com/applications/… on Your application - Edit Applications page) with the internal address of my Home Assistant server. After then, I can Linked the account and Approved it.

driesken · March 18, 2019, 9:10am

I’m having some trouble with this plugin. I’ve configured it as a custom_component and did all of the steps above.

However, when I’ve linked my account, I only get a blank popup afterwards. I suppose the callback is successfull since there is a “.homeconnect-token-cache” which contains “id_token”, “refresh_token”, etc. But no sensors are showing up?

DavidMStraub · April 5, 2019, 11:23am

Hi,

that’s strange. Are you able to access your devices with the Home Connect (phone) app? Which types of devices do you have?

driesken · April 5, 2019, 11:36am

Strangely after a few days, this suddenly started working. Must have been some delay with the activation of the project.

Everything is working great, too bad that remote start is disabled after 24 hours.

taikapanu · April 7, 2019, 3:41am

Is the SSL sill the only way of using this component? Now that the Cloud system has nice remote access feature

I just bought a set of home connect compatible washing tower but prior this did not do extensive research regards the IOT stuff.

DavidMStraub · April 7, 2019, 10:52am

It’s the Home Connect API that requires SSL. I never looked into HA cloud and have no idea if it’s possible.
