HVAC Mode Mapping, Temperature, and Fan Mode Issues on Daitsu Urban AWD30 (Gree Versati III All-in-One)

[tonimg87]

Hello Rob,

First, many thanks for your work on this Home Assistant integration! I'm using it with a Daitsu Urban AWD30 (Gree Versati III All-in-One) heat pump, and while basic control works, I'm encountering several issues that seem to stem from differences in how my unit handles Gree protocol commands.

Here are the main problems:

Incorrect HVAC Mode Mapping:
When I select certain HVAC modes in Home Assistant, my Daitsu unit performs a different function than expected. It appears the Mod (mode ID) values sent by the component do not align with what my specific Daitsu model expects.

For example:

Selecting HVACMode.COOL in HA currently causes my Daitsu to activate Heating without DHW.
Selecting HVACMode.FAN_ONLY in HA currently causes my Daitsu to activate Cooling + DHW.
I've been gathering debug logs while testing with the official Daitsu app to identify the correct Mod values for my unit's functions (e.g., actual Cooling, Heating, Fan Only, DHW). Is there a recommended way to adjust these HVACMode to Mod mappings within the component's configuration or code to match my specific device?

Temperature Control Problem (SetTem: 0 always sent):
When I attempt to set the target temperature in Home Assistant, the component's debug logs consistently show that SetTem: 0 is sent in the command payload to the Daitsu unit, regardless of the temperature I select in the UI. This prevents me from controlling the target temperature effectively.

Non-existent Fan Modes:
My Daitsu Urban AWD30 only supports a 'Quiet' fan mode. However, the Home Assistant UI for this integration displays multiple fan speed options (e.g., low, medium, high, auto) which are not functional for my device. This causes confusion and potential errors. Is there a way to limit the exposed fan modes to only those truly supported by my unit?

I can provide detailed debug logs

Any guidance or assistance you could offer on these issues would be greatly appreciated.

Thank you again for your time and work!"

Hi @tonimg87,

In all honesty: This component has not been created for heatpumps. Thats why it's not working as intended.

Also I dont have any systems to test this for, so this is going to be really hard to build & test here.

You could build a fork of this integration which supports heatpumps. If you make it work with an option where you can switch between HVAC vs Heatpump mode, we could integrate it into this component. Feel free to create a PR for this.

Long story short: This is not supported with this component at this time, nor do I have the options to create & test such support.

[tonimg87]

I completely understand that this component wasn’t designed for heat pumps, and I appreciate your honesty about the limitations. That said, I must say that this integration has been the one that best understands and communicates with the Gree Versati III unit — much better than any other solution I’ve tried so far. So thank you for the great work you've done.

I'll look into the possibility of adapting the code to support a heat pump configuration, or maybe adding a selectable option when adding the device to specify its type. Hopefully, that could help extend the usefulness of this integration to more users. Thanks again for your work and openness to contributions.

[RobHofmann]

That would be great! It's nice that you are willing to contribute to a better product :).

Nice! Do you see a way where we can merge these two modules together?

[joagonca]

I have the same problem as @tonimg87 . The functionality mapping is different, and from the communication protocol, I cannot directly understand that it's with a Heat Pump, and not an AC unit, that I'm dealing with. It also doesn't help that I don't have an AC unit that talks the Gree protocol.

Moreover, there are other functionalities like "Desinfect", "Fast heat", etc., that I don't see in these AC units, and not sure if they'd map to a different functionality or if they're independent ones. Another one is the temperature readings; if it's a field that allows setting (or it's not a float), the value is the centigrades directly. Otherwise, it's broken in two separate fields and it needs an operation to combine them (like the Water Tank temperature).

This to say, that once I finalise all the details to talk with the Heat Pump, I'll check your work more thoroughly to see if we can match @RobHofmann :)

Cheers!

"It works pretty well. My only concern is that sometimes the 'state' briefly shows as 'unknown' right before an update, which temporarily blocks parameter modification. It's a minor quirk, but overall, from what I've tested so far, it performs really well."

[joagonca]

@tonimg87 as to don't further hijack this thread, we can continue this conversation on the other repo. I know that issue. That only happens if you have any other application (like the Android one), polling the Heat Pump as well. The controller only supports one connection at once, and once Home Assistant fails to retrieve status, he tries to rebind, hence the brief 'Unknown' :)

Or we simply create a dual stack where we can switch based on the (user entered) "mode" --> HVAC vs Heatpump.

Looking forward to your analysis!

This is what I, with a huge assistance from an AI buddy, produced: https://gist.github.com/crazyfacka/0ba4daea49164a03a7ff528495d8bc96

Don't have the time for such commitment as of today. But looks promising.
