Manual Cooling for x days

[switschel]

Before requesting a new feature / a new sensor

• The feature I'm requesting exists in the myVAILLANT app, and I attached a screenshot
• I tested the latest release, and it's missing there
• I've attached exported data of my system

Describe the feature you want

With the latest app update manual cooling for x days is supported now. It would be great if this integration would provide a service to do the same via Home Assistant.

Let me know if I can help to discover the correct API to do so.

Screenshot

Export data

Not sure if it is relevant but if so I can provide it. I reviewed it but it would be not very helpful to implement this new service I guess.

Attach exported test data here

Should work in https://github.com/signalkraft/mypyllant-component/releases/tag/v0.8.5

Unfortunately not working for VRC700:

True, that would require someone with a VRC700 to do some reverse engineering and find out what values are being sent to which endpoint.

@signalkraft

Here you go:

POST 	https://api.vaillant-group.com/service-connected-control/vrc700/v1/systems/<systemID>/cooling-for-days

Payload: 
{
    "value": 1
}

DELETE https://api.vaillant-group.com/service-connected-control/vrc700/v1/systems/<systemID>/cooling-for-days

No payload

value == int number of days

[signalkraft]

Thanks for the data, should be fixed in https://github.com/signalkraft/mypyllant-component/releases/tag/v0.8.6

[switschel]

Thanks for adding it so fast!
Here are my test results:

1. Calling service "cooling for days" providing the number of days is working as expected

2. Calling service "cancel cooling" still results in an error:

3. There is no "cooling" switch available to activate cooling from a Dashboard / Device.

Both issues should be fixed here! Let me know if the switch behaves as intended, I have no idea if VRC700 controllers use the same data structure for tracking the state of manual cooling.

[switschel]

1. and 2. are working now.

2. Cooling switch still is not appearing for VRC700
   I have this binary_sensor.home_circuit_0_cooling_allowed which is "on" and I guess this is not working as intended:

Good catch, let me know if https://github.com/signalkraft/mypyllant-component/releases/tag/v0.8.9 fixes that!

Switch is there but when trying to use it:

Maybe default it to "1" when switching on?

[signalkraft]

https://github.com/signalkraft/mypyllant-component/releases/tag/v0.8.11 3rd time 4th time's the charm?

[switschel]

It's partially working now.
I can toggle the button but it will be deactivated directly again. Also the days I have defined will be overwritten with 30 all the time. So I have to toggle the manual cooling button once more and then it is activated (for 30 days). After some time the button is deactivated even the manual cooling is on. I guess there is some kind of state missing leading to this behavior? If so I can try to discover the correct one using reverse engineering again.
