Climate 1.0: Restore turn_on functionality in UI

[OnFreund]

Following the discussion in #3468 I'm opening a new ticket to cover the ability to turn a climate device on (both in the lovelace card and in the thermostat dialog).

The backend does have a turn_on service, but it's not exposed through the UI.

[OnFreund]

Proposed implementation for the lovelace card: create a toggle service for climate, and call that when clicking the on/off button, instead of set_hvac_mode.

This is still something I believe should be in the product

[zsarnett]

This is something that is available via the more info icon. All options will not be added to all cards

[OnFreund]

@zsarnett this is not available via the more info icon as far as I can see. Please reopen.

Not stale

[zsarnett]

Looking into this. I am not seeing where in the backend that the Climate integrations says it supports Turn_off/Turn_on

Maybe its something they all support but I would like to be able to check support in the integrations before offering a button incase it doesn't do anything

Also https://github.com/home-assistant/core/blob/dev/homeassistant/components/climate/const.py#L126-L132 I am not seeing where we have this turn on service

[OnFreund]

@zsarnett the basic component supports it, and platforms can override with their own behavior:
https://github.com/home-assistant/core/blob/dev/homeassistant/components/climate/__init__.py#L110
https://github.com/home-assistant/core/blob/dev/homeassistant/components/climate/__init__.py#L464

One more thing:

before offering a button incase it doesn't do anything

The button is already there, and doesn't do anything if the device is off. I'm suggesting it does do something :) (I've also seen some confusion on discord with people who thought that's the way to turn on the device, and I've seen custom integrations that let their turn_off service toggle so that it turns on.).

[zsarnett]

I see that it fakes it if it doesn't support it.

[zsarnett]

The button is already there, and doesn't do anything if the device is off

Its in a list of modes. It does what it is supposed to do
On is not a mode

[OnFreund]

I see that it fakes it if it doesn't support it.

The so-called "fake" turns the device on, and that's only the fallback for platforms that don't implement their own turn-on functionality. Most climate devices I've seen throughout my life have a turn-on button.

Its in a list of modes. It does what it is supposed to do

That's not necessarily how users perceive it.

[zsarnett]

I am not sure this is something we want to add to the frontend because it doesn't act as a user would think.

I think the backend needs to implement a support turn on and support turn off. So that we only show when the integrations supports this feature.

Reasoning: If I turn off my Thermostat while it is in Cool Mode. It goes to off. But if I turn my Thermostat back on, its not guaranteed that it goes back into Cool Mode. In my testing, it always went in Heat Mode. This experience is not what I want to implement.

Raise an issue with the backend or a Feature Request in the forums to have this functionality implemented. And then we can implement this in the frontend.

[OnFreund]

This was already discussed at length on the backend side post Climate 1.0. The decision was to add a turn_on service, and fallback to HVAC_MODE_HEAT_COOL, HVAC_MODE_HEAT, HVAC_MODE_COOL (in this order), and hence the implementation we have today.
This frontend issue was opened after the service was added back.

[OnFreund]

@zsarnett, I managed to dig it up:
This is where I proposed a flag: home-assistant/architecture#261
This is where that proposal was rejected: home-assistant/architecture#261 (comment)
This was the PR that added the current behavior: home-assistant/core#25026

[OnFreund]

@zsarnett any thoughts on the links I provided?
Thanks!
