Added support for Vaillant Thermostat, how to integrate in official release

mrappz · June 28, 2020, 10:53am

Hi, I have the last version, because I have installed it yesterday (Version 0.111.4)

mrappz · June 28, 2020, 11:09am

You only need to change the two lines in which ClimateDevice exists for ClimateEntity, and it works without any warning, you must change these lines on climate.py file

Kenan_Elmas · June 28, 2020, 1:24pm

i don’t know why but not working on my side. same error always.

Kenan_Elmas · June 28, 2020, 4:44pm

Would you please share with me your config files in vaillant folder? I reinstall hassio and get same result below;
“ModuleNotFoundError: No module named ‘custom_components.vaillant.remote’”

Do you copy the script here?

The steps you must do are the following:
1.- Create this folder (you can do it using File Editor add-on)
/config/custom_components/vaillant
2.- Download the py files from github and upload the files on the folder that you have created on step 1
3.- Edit configuration.yaml and add the following lines:

climate:
- platform: vaillant

vaillant:
api_key: na_client_android_sdbg
secret_key: !secret key_vaillant
username: !secret usuario_vaillant
password: !secret password_vaillant
discovery: False
app_version: 1.2.0.2
user_prefix: sdbg

I have the data on the secret.yaml file, the username and password are the ones that you use of your MiGo app on the phone, and the secret key is obtained with the procedures explained on previous comments on this thread.

Hi, I tried to integrate my MiGo with the custom component of pjmaenh.

I have copied the directory vaillant (from pjmaenh github) in /config/custom_components/ directory with its 3 files (init.py, climate.py and const.py). I have other components in that directory like hacs, so it is the right one. I have verified the typo several times.

I have changed ClimateDevice string to ClimateEntity in climate.py file.
I have used this following configuration in configuration.yaml file.
climate:

platform: vaillant

vaillant:
api_key: na_client_android_sdbg
secret_key: 28d3***********ffeb
username: my username used on android app
password: my psw used on android app
discovery: False
app_version: 1.2.0.2
user_prefix: sdbg

I have used a oneline decompiler and find the api key in a source direct with app_version and api_key as well.

When I restart my HA (raspby) it starts very slowly. Everithing is up to date. I have the last version of HA. I get the message that HA is starting and some components will will not be yet available but the message never desappears.
Some components does start at all.
I have no error message regarding vaillant component like some of you (invalid_client or something else).

Does anyone have an idea where is the problem ?

thanks for your help.

It seems that the config is ok, and the secret key seems to be ok too.

I have some troubles sometimes when I restart the server, and if the thermostat do not load, I open the app on the phone and then I restart HA, and usually it works

Yesterday I had some problems to access the thermostat info even on the phone app.

pjmaenh · July 7, 2020, 12:56pm

Vaillant/Bulex is a rebranded netatmo device, they even use the netatmo API and recently, Vaillant bought netatmo. So that’s why

pjmaenh · July 7, 2020, 1:00pm

For anyone still having this warning:

ClimateDevice is deprecated, modify VaillantThermostat to extend ClimateEntity

I just merged the PR of @alexbelgium (thanks!) so update/pull the component and this warning should be gone.

!Kenan_Elmas: custom_components.vaillant.remote does not exist, so I have no idea where this is coming from. Most likely you have some error in your configuration.yaml, maybe something like this:

vaillant:
  ...
  remote:
    ...

Maybe an indentation error?

Kenan_Elmas · July 8, 2020, 1:54pm

@pjmaenh It is crazy error that i deleted # added lines (unused code) with notepad++ and it worked. No idea about reason

liuk4friends · July 11, 2020, 7:51pm

Thank you all guys,
this thread was helpful … my brand new Vaillant vSMART thermostat is working flawlessly with HA!

Have a nice weekend

kitof91 · July 21, 2020, 2:43pm

Just to tell You that I have solved my problem. It was a rookie mistake.
The problem was because I downloaded the files incorrectly. The files included the html code from the github page…
Thanks for your great job on this component.

arturonaredo · August 14, 2020, 11:23am

Hi @pjmaenh, my heater is using Sanieur Duval MiPro instead of MiGo, I’ve decompiled the android application and I see no na_client_android_sdbg, nor api key nor secret key. It seems that is getting the token on a TLS request. Do you think the api token and secret key could be the same of MiGo?

The api endpoints found are:
https://smart-2.vaillant.com/mobile/api/miPro/
--------------------------------------------------/v4/
http://vr900.vaillant.private/

Could you share with me the MiGo api_key and secret_key if you think its worth to give a try?
[EDITED]

I’ve checked MiGo and the endpoint is api.netatmonet/oauth2/token, not sure if the py script is changing the api endpoint to support vaillant.

Thanks in advance.

pjmaenh · August 14, 2020, 11:49am

Given that the API endpoints are totally different, I am afraid it will not work.
I don’t have a MiPro, so I cannot test it out or develop a modified version I’m afraid… (unless someone want to sponsor me a MiPro ).

I’ll send you the MiGo config in a PM.

pjmaenh · August 14, 2020, 11:56am

Also note that this component is just a Home Assistant wrapper around the pyvaillant library, available at https://github.com/pjmaenh/pyvaillant.

If you want to modify the component yourself to work with the MiPro, start by modifying this library. You don’t need the home-assistant-vaillant component or HA to do so, just python and the pyvaillant library.

Hi,
suddenly I can’t find anymore my vaillant integration. I’m using Home Assistant 0.114.4

In logs I have:
