Expose LG's sleep mode function

Enable sleep mode for LG's AC devices

This PR exposes sleep timer as a switch. This mode reduces energy consumption and fan noise, it also introduces some automatic adjustments

Detailed explanations from LG's user manual:

• In the Cooling and Dehumidification Mode, the
  temperature increases by 1 °C after 30 minutes
  and additional 1 °C after another 30 minutes for a
  more comfortable sleep.

• The temperature increases up to 2 °C from the
  preset temperature.

• Although the remark for fan speed on the display
  screen may be changed, the fan speed is adjusted
  automatically.

Use case

In a hot night we can setup an script/automation which will balance conform and energy consumption

• Enable jet mode for X minutes or until temperature reaches Y degrees
• Then, change to cool/dry mode for certain amount of time or until temperate reaches lower threshold
• Finally, enable "sleep mode" for the rest of the night.

Why is better that automations or auto mode?

The first two steps are doable with current H-A capabilities but the third, in my experience, can't be reproducible with any combination of fan speeds or temperature. Also, LG's devices beeps each time a settings is changed. Changing settings in the middle of the night via some automations can result in a orchestra of beepings. LG's sleep mode doesn't have this problem.

Further work

This PR is presented as first approach to integrate sleep mode.

Currently it's exposed as a switch. When enabled, this mode is activated with a 7 hours timer. After 7 hours it goes back to off.

Further discussion and work should determine other behavior as:

• it's the 'switch' control the right interface?
• should the timer be autoreset before it goes to 0?
• should be the default timer 7 hours?

• it's the 'switch' control the right interface?

My opinion is that this should be implemented as a service with a parameter to set the duration.
A sensor can be used to identify if the function is enabled.

@ollo69, done

services are not my best skill but I based my code on your existing ones.

Please take a look to my comments

@ldotlopez,

I did some changes on the logic used to control if status is available, range used to call the service and service availability.
I also rebased branch with master.
Please check if everything look fine for you and ask if something is not clear,

If ok I think we can merge.

Thanks.👍

@ollo69

It's OK for me.

Thanks 👍

I've been looking forward to the sleep mode, but it looks like this does not work correctly on my device (LG I38TKF - 3 ton, split inverter) - I can't see the switch entity for the sleep mode. Moreover since 33.3 the jet mode switch is now shown as unavailable - might be related?
It does properly expose the entity _sensor.sleep_time . Is there any specific procedure to reload all entities to recognize/expose/identify the new switch? (besides removing and adding again?).

I tried re-enrolling a new account on another HA instance with latest SmartThinQ LGE Sensors integration (0.33.3) and the problem is the same - the device is controllable, but the sleep button is still not discovered (sleep_time is there and it is properly reporting when sleep mode is initiated from the app).

Can I share any logs with devs? Maybe this could help fixing this bug?

Hi @gitmarecki

You should file an issue for better tracking.

However, I can only talk about sleep mode which is the feature I developed: there is not sleep button, you should call the smartthinq_sensors.set_sleep_time service to start sleep mode.

how did I miss that? :D It works! THANK YOU! where's the buy-me-a-coffee button? :-D
