No automations at play.

Heres a little clip of it in action:

Sorry about that. Re-uploaded it and allowed embedding.

Add this to your configuration.yaml file:

logger:
  default: warning
  logs:
    homeassistant.components.daikin: debug

Restart, and try setting the temperature again. Wait for it to fail/revert and paste the system debug log here.

You will need this log for your issue too.

iebooker · April 13, 2022, 5:26am

I put in that code, restarted and tweaked the temperature and I’m not seeing anything in the logs.

tom_l · April 13, 2022, 7:25am

Then the integration isn’t doing anything.

iebooker · April 13, 2022, 4:33pm

Yea that sounds like a bug for sure.

I also tried with another snippet of code in the configuration.yaml

logger:
  default: info
  logs:
    homeassistant.components.daikin: notset
    pydaikin: notset

I found this bit of code from @fredrike in another thread regarding Daikin AC’s.

Restarted, reproduced temperature change issue, checked logs, nothing at all.

fredrike · April 13, 2022, 5:41pm

I’ve seen the issue. The thing is that “it worked before”, we need to know the last version when it worked as expected so we can trace the changes.

Daikin AC Temperature jumps after being set

opened 05:32AM - 13 Apr 22 UTC

integration: daikin

### The problem When I set a Daikin AC unit to a temperature, after approximate…ly 90 seconds the temperature will change automatically to something else. For example: I set the temperature for 60° F in the “Heat” mode and after about 90 seconds the set temperature will change to 68° F. If I use the official Daikin App, [Comfort Control app](https://daikincomfort.com/products/thermostats-controls/daikin-comfort-control-app), this doesn’t happen. I set a unit at 60° F and it stayed at 60° F. I have never noticed this behavior before with HA and the Daikin units. I’ve been using HA with the Daikin units for over 2 years. ### What version of Home Assistant Core has the issue? core-2022.4.3 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running?

Updated issue with my best guess as when it was working correctly, Release 2022.3.8

asloan5 · April 15, 2022, 2:30pm

I have a similar issue with my Daikin‘s all of a sudden they’re normally set at 75 Fahrenheit if I try to change it it shows to be changed for about 90 seconds or so then It goes back to the 75°F. I can change it manually with the remote control and once I do so if I try to change it off of that number it keeps going back to whatever I set it at with the remote control. The other functions of the Daikin integration seem to work fine just temperature adjustment is where I see the problem.

fabianluque · April 16, 2022, 3:29pm

Experiencing same issue after installing a new adapter mid February 2022, so at least 2022.2.x I think.

fabianluque · April 21, 2022, 1:15pm

I’ve updated to 2022.4.6 which contains a fix for this issue. I’m still experiencing issues.

fabianluque · April 21, 2022, 3:38pm

Ok, did some digging and this is what I’ve found. I’m currently running 2022.4.6, my unit has a BRP072A43 module (fw 2.9.0). Daikin Comfort App 2.0.

Below is a table to show the temperature in Fahrenheit being set in HA, temperature sent through the integration, temperature sent when using the app configured in Fahrenheit, when it succeeds changing the temperature in the unit.

F temp  stemp ha    stemp app   changed temp in unit
68      20          20          yes 
69      20.6        20.5        no
70      21.1        21          no
71      21.7        21.5        no
72      22.2        22          no
73      22.8        23          no
74      23.3        23.5        no
75      23.9        24          no
76      24.4        24.5        no
77      25          25          yes
78      25.6        25.5        no

@fredrike Should I create a new issue in Github for this?

So the fix for this issue didn’t solve the issue?

I think you should create a new issue and tag @vanackej, it is he who introduced the issue so he should fix it.

Edit: It seems like you need to send decimal .5, something like this should fix it: rounding - Round to 5 (or other number) in Python - Stack Overflow

Or, start using Celsius (from the great Swedish inventor Anders Celsius) like the rest of the world

fabianluque · April 22, 2022, 7:59pm

Thanks @fredrike. Not so sure @vanackej was the one that introduced the issue. Not really sure if this rounding has always been needed and no one noticed or it’s due to a recent firmware upgrade on the adapter itself.

I’ll create the issue anyway and tag you both. Hopefully could be fixed soon.

Daikin AC temperature reverting back after being set

integration: daikin

### The problem When I set a Daikin AC unit to a temperature, after some time… (could be 30-90 seconds) the temperature will change automatically to the previous value. For reference, this is my current setup: - Home Assistant Core 2022.4.6 - My unit has a BRP072A43 module (firmware 2.9.0) - Daikin Comfort App 2.0 Below is a table that shows the temperature in Fahrenheit being set in HA, temperature sent through the integration, temperature sent when using the app configured in Fahrenheit, when it succeeds changing the temperature in the unit. ``` F temp stemp ha stemp app changed temp in unit 68 20 20 yes 69 20.6 20.5 no 70 21.1 21 no 71 21.7 21.5 no 72 22.2 22 no 73 22.8 23 no 74 23.3 23.5 no 75 23.9 24 no 76 24.4 24.5 no 77 25 25 yes 78 25.6 25.5 no ``` As you can clearly see in the table above, it seems the adapter is expecting the rounding to be .0 or .5, otherwise it won't work. If I use the official Daikin App, [Comfort Control app](https://daikincomfort.com/products/thermostats-controls/daikin-comfort-control-app), this doesn’t happen. The app is rounding properly as the adapter expects it. I have been noticing this issue since I installed a new adapter mid February 2022, so not sure if it's been happing before that time. Tagging @fredrike and @vanackej for reference as they are aware of this issue and past issues. Please let me know if you need further info from me. Happy to help in any way I can. ### What version of Home Assistant Core has the issue? core-2022.4.6 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running? Home Assistant OS ### Integration causing the issue Daikin ### Link to integration documentation on our website https://www.home-assistant.io/integrations/daikin ### Diagnostics information _No response_ ### Example YAML snippet _No response_ ### Anything in the logs that might be useful for us? ```txt Put in the following code into configuration.yaml: logger: default: warning logs: homeassistant.components.daikin: debug pydaikin: debug You'll be able to see the temperature sent to the unit by the integration This is an example of a log line showing the data sent to the adapter by the integration: 2022-04-21 11:20:43 DEBUG (MainThread) [pydaikin.daikin_brp069] Sending query_c: aircon/set_control_info?pow=1&mode=4&stemp=23.3&shum=0&f_rate=A&f_dir=3 ``` ### Additional information _No response_

Agree with you, it seems the adapter is expecting a rounding to .0 or .5 for some reason.

vanackej · April 22, 2022, 9:42pm

Rounding to .5 implemented, hope it will fix the issue.
I think there were some incorrect behaviors for users using Fahrenheit units before my initial contribution, but it definitly made it worse, sorry

fabianluque · April 25, 2022, 1:40pm

@vanackej @fredrike After updating to 2022.4.7 temperature is being set properly now. Thank you so much for fixing this!
