Cannot set program with Viessman Vitodens 100w

[hnykda]

Hi. I have a E3_Vitodens_100_0421 and I am trying to set active programs. The programs seem to be available via circuit.getPrograms(), but I cannot set them apparently. Do you happen to know if this a limitation of Viessman API or can something be done about it? It's really limiting, as what I would want to do is to e.g. set up the gas boiler to go to reduced program when no one is at home, but at the moment I can only use circuit.setMode which basically only has off (~standby) or on. An alternative is to set comfort, normal and reduced temperatures to the same (low) value and then bring them back again.

from PyViCare.PyViCare import PyViCare


def circuit_factory():
    client_id = "<clientid>"
    email = "email"
    password = "<passwd>"

    vicare = PyViCare()
    vicare.initWithCredentials(email, password, client_id, "token.save")
    device = vicare.devices[0]
    
    t = device.asAutoDetectDevice()
    c = t.circuits[0]
    # c.getPrograms()
    return c

circuit = circuit_factory()
circuit.getPrograms()

spits out:

['active',
 'comfort',
 'forcedLastFromSchedule',
 'noDemand',
 'normal',
 'reduced',
 'standby',
 'summerEco']

but when I try to activate it:

In [34]: circuit.activateProgram("reduced")

Any ideas? Thanks!

I saw a similar behaviour: in my setup i'm not changing the mode anymore but i'm acting directly on the setpoint. If you want I can share the automation @hnykda

[hnykda]

Hey. Thanks for the offer, I have solved that by using pyscript (very easy, actually) setting the setpoints directly as well, so I'm fine, thanks!

@cagnulein @hnykda Same problem here. Would you mind sharing your automation to directly set the setpoints? Thanks!

[hnykda]

Sure!

1. install HACS if you don't have it already
2. install pyscript via HACS
3. move https://gist.github.com/hnykda/03c3b7c3cab328223651e58bc6c7e899 to /config/pyscript/vicare_manual_set.py

then you can use it as a service like this:

    service: pyscript.set_default_temperatures
    data:
      reduced: 12
      normal: 18
      comfort: 20

Perfect, works beautifully. I have two heating circuits and created two scripts, so I have a separate service per circuit.
Thanks for your help!

[hnykda]

No worries, happy to help. FYI it would be nicer if you added that circuit as a function parameter instead of having two files 🙈

Hi, just a small question you might have experience with. After API issues I had to remove the vicare_token.save file and reload the vicare integration in HA.
The vicare integration works fine now but I get this error for vicare_manual_set.
It seems like pyscript is using another token file but I don't know where that is stored.

Exception in </config/pyscript/vicare_manual_set.py> line 27: circuit = circuit_factory() ^ PyViCareInvalidDataError: {'viErrorId': 'req-fc4cdd27e51c47c7b3b59237deab4b2c', 'statusCode': 401, 'errorType': 'UNAUTHORIZED', 'message': 'Request contain invalid token', 'error': 'NO TOKEN AVAILABLE'}

I'll answer my own question: I changed a line in the script, modifying the name for the token.
vicare.initWithCredentials(email, password, client_id, "tokenpyscript.save")
I think both the vicare integration and vicare_manual_set were accessing the same token file.

[hnykda]

Aha! That might be the issue I have been seeing in my installation for the last couple of days. Thanks for the tip, I will monitor if that helps.

In my experience I can activate comfort or eco mode, but not normal. What I did, to get normal, was a script where eco mode if activated and then deactivated. Then it goes to normal.

since I upgrade my home assistant (I think) I'm having issues where the command to change the temperatures often doesn't work. This error is logged
