Hello, this is my first time posting, and I’m still a very inexperienced Home Assistant user. If there’s better ways for me to ask for help, please let me know 
I am using the Daikin integration and I am interested in getting some Automations and Scenes going. So far I’ve experimented with a simple Automation (configured using the UI editor) to turn on/off the AC using a Service call. Using a time-based trigger I was able to get something to work.
Now, about Scenes. As I understand it, you compose a Scene in HA by describing how things (entities) should be, and then you can activate a scene from a dashboard. If my understanding is correct, what I would like is to define a couple of basic climate scenes, such as:
- No AC
- Night-time AC - set HVAC to “cool” and a predefined temperature
Using the UI editor (via Devices > Scenes > + button), I tried to create these. After a bit of clicking around, and some slight YAML tweaks, this is the YAML config for the two scenes:
- id: '1666607473867'
name: Turn AC off
entities:
climate.daikin_ac_2:
hvac_modes:
- fan_only
- dry
- cool
- heat
- heat_cool
- 'off'
min_temp: 7
max_temp: 35
target_temp_step: 1
fan_modes:
- Low
- Mid
- High
#current_temperature: 25
#temperature: 25
fan_mode: Low
hvac_action: 'off'
friendly_name: Daikin AC
supported_features: 9
state: 'off'
metadata: {}
- id: '1666610791078'
name: Night-time AC
entities:
climate.daikin_ac_2:
hvac_modes:
- fan_only
- dry
- cool
- heat
- heat_cool
- 'off'
min_temp: 7
max_temp: 35
target_temp_step: 1
fan_modes:
- Low
- Mid
- High
current_temperature: 21
temperature: 21
fan_mode: Low
hvac_action: cooling
friendly_name: Daikin AC
supported_features: 9
state: cool
metadata: {}
icon: mdi:moon-waning-crescent
Unfortunately, the scenes do not work as expected. I have created a GIF to demonstrate how the AC changes when I activate each scene.
The summary is:
- “Turn off AC” momentarily turns it off, but then something turns it back on again (and you can see this in the Logbook).
- “Night-time AC” momentarily changes the temperature (to 21), but then something overrides it and it goes back to what it was (to 20).
What I would love to know is:
- How do I better understand what is causing the momentary changes? The logbook doesn’t provide any more depth.
- Is this a potential bug in the Daikin integration? Or somewhere else? If so, do I need to report it on Github for it to be looked at?
- Am I using Scenes correctly? I would assume so… but then again the Automation config seems so much easier. Is it common to achieve what I want using Automation instead of Scenes? (Or Scripts, perhaps? I haven’t look into those yet.) I wonder if the buggy behaviour is caused by trying to set state on the entity, rather than service calls?
Thanks in advance!
