Manual Cooling for x days

[switschel]

Before requesting a new feature / a new sensor

• [x] The feature I'm requesting exists in the myVAILLANT app, and I attached a screenshot
• [x] 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

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: Traceback (most recent call last): File "/usr/src/homeassistant/homeassistant/components/websocket_api/decorators.py", line 28, in _handle_async_response await func(hass, connection, msg) File "/usr/src/homeassistant/homeassistant/components/websocket_api/commands.py", line 793, in handle_execute_script script_result = await script_obj.async_run( ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 1770, in async_run return await asyncio.shield(create_eager_task(run.async_run())) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 465, in async_run await self._async_step(log_exceptions=False) File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 529, in _async_step self._handle_exception( File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 559, in _handle_exception raise exception File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 527, in _async_step await getattr(self, handler)() File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 764, in _async_call_service_step response_data = await self._async_run_long_action( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/helpers/script.py", line 727, in _async_run_long_action return await long_task ^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/core.py", line 2731, in async_call response_data = await coro ^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/core.py", line 2774, in _execute_service return await target(service_call) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/helpers/service.py", line 999, in entity_service_call single_response = await _handle_entity_call( ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/src/homeassistant/homeassistant/helpers/service.py", line 1071, in _handle_entity_call result = await task ^^^^^^^^^^ File "/config/custom_components/mypyllant/climate.py", line 537, in cancel_cooling_for_days raise ValueError("Can't cancel cooling for days on VRC700 systems") ValueError: Can't cancel cooling for days on VRC700 systems

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!

[switschel]

Switch is there but when trying to use it:

Maybe default it to "1" when switching on?

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