Documentation: List of params?

[haraldhh]

Where can I find the list of params that my AC provides, and an explanation what each parameter does?

A thousand thanks for this, I love this CLI utility. I will buy You a beer if I ever meet You.

[marcinlubojanski]

I got it by taking packet trace from the Gree app :D
No official list available and not everything is there (f.e. outside temperature is missing for my heat pump).
I've made my own automation and exporting data to Grafana :)

List of parameters that I've found (valid for Versati III):
Pow Mod CoWatOutTemSet HeWatOutTemSet WatBoxTemSet TemUn AllErr TemRec ColHtWter HetHtWter TemRecB CoHomTemSet HeHomTemSet FastHtWter Quiet Emegcy LefHom SwDisFct SvSt VersatiSeries RomHomTemExt WatBoxExt FocModSwh Emegcy HanFroSwh WatSyExhSwh BordTest ColColetSwh EndTemCotSwh ModelType AllInWatTemHi AllInWatTemLo AllOutWatTemHi AllOutWatTemLo HepOutWatTemHi HepOutWatTemLo WatBoxTemHi WatBoxTemLo RmoHomTemHi RmoHomTemLo WatBoxElcHeRunSta SyAnFroRunSta ElcHe1RunSta ElcHe2RunSta AnFrzzRunSta TemUn AllErr

Temperatures that consist of high and low byte are calculated with formula (Hi - 100) + Lo/10

[haraldhh]

Thanks. How did you get that list? Disassembling the Android app or listening to the communication and tcpdumping it while pressing all buttons?

Some are documented here, with explanation: https://github.com/tomikaa87/gree-remote I think I will manage with those known ones. Just want to be able to run it a 8°C or 16°C depending of the market price of energy.

[marcinlubojanski]

tcpdump, then decode it with the key which you can get with gree.py

[haraldhh]

Guessed that :)

Thanks for that list. Tried them all on my new Gree GWH09AGA-xxx heatpump. Not all of the parameters Your machine supports are supported by mine, which is expected.

It does support StHt which is nice, this is the 8°C setting.

[haraldhh]

Is there a way to read individual temperature sensors in a Gree AC? The outside temp sensor would be nice to be able to read.

[rubenRP]

Thanks @marcinlubojanski. Did you find the relation of variables with Status View Params (Specifically, compressor, fan and HP-pump)?

[marcinlubojanski]

Thanks @marcinlubojanski. Did you find the relation of variables with Status View Params (Specifically, compressor, fan and HP-pump)?

Unfortunately not. The app is not trying to get them so don't know the variable names. I was trying to guess outside temperature for few days with millions of combinations but no luck. And of course there is no official documentation whatsoever.

[kostirez1]

Here are some parameters that I've found by intercepting the firmware update v3.73 file from http://52.59.83.129/wifiModule/image/10132/183744 - ota_sdkshell-5421341282129789759-110255171350184864.bin.
Since this host seems to be not available anymore, here is a mirror: https://ulozto.net/file/NinekwAQ2xiF/ota-sdkshell-5421341282129789759-110255171350184864-bin

Here is a full dump of all strings in this binary using the "strings" utility: https://gist.github.com/kostirez1/b9588e4f355a8bb974a282af439fafb1
And a list of strings that I suspect to be the parameters: https://gist.github.com/kostirez1/7140739d2d49d60f11eee7552b6e10b9

Some parameters may not be available depending on the model of your unit, or the current firmware version. Most of the AC related ones did still work on another unit, which is currently stuck on v1.05.

The latest version of Gree+ app shows the outside temp now when requested thru the app. If you get the time, can you please see if you can find out the outside temp param?

[marcinlubojanski]

Which version? I have 1.17.2.7 on Android and it's not there, or maybe it depends on device type?

[rroyGit]

Same version. I bought the system recently, so it is likely the latest version - https://www.greecomfort.com/our-products/livo-gen4-wall-mount/

On the app, it's called "Outside HUM", sits next to Sleep option.

edit -Ops, my bad, it's just the humidity ;'(

Anyway, this free weather api serves my need for the moment - https://open-meteo.com/en/docs

[mkaluza]

@marcinlubojanski so I looked at the firmware for my device (multisplit AC Pular) here:
https://github.com/maxim-smirnov/gree-wifimodule-firmware/tree/main/362001065279

and got a lot more params. For outside temp, try OutEnvTem or TemsSenOut - for me both show the same value (that changes). Probably is also +40 offset, b/c it said 71 and 70, and there's 30+ deg outside right now.

Just find your firmware and look for any known name (like TemSen) - you'll get them all

[marcinlubojanski]

@mkaluza I tried both those params but they don't work on my device :/
Also not sure where from I could download firmware for Gree Versati III monoblock... This gree wifimodule seems to be different thing.

[mkaluza]

@marcinlubojanski
Hi, sorry, I missed the notification.
you need to get your device type 'code' first. If you do a search with --verbose param, you should see sth similar to this:
search_devices: pack={'t': 'dev', 'cid': '9424b8bafe16', 'bc': '00000000000000000000000000000000', 'brand': 'gree', 'catalog': 'gree', 'mac': '9424b8bafe16', 'mid': '10001', 'model': 'gree', 'name': '', 'lock': 0, 'series': 'gree', 'vender': '1', 'ver': 'V2.0.0', 'ModelType': '32792', 'hid': '362001065279+U-WB05RT13V1.23.bin'}

you can also just do 'get hid' - it is the same property as all other

First part of the 'hid' field is your model 'code' (mine here is 362001065279).
Then you go here
https://github.com/maxim-smirnov/gree-wifimodule-firmware/tree/main
and check if your fw is there. If it is, just get it, if it is not, check out the repo and run
firmwareFetch.py YOUR_MODEL_CODE

you don't even need to checkout b/c the script just checks a series of urls like this:
https://github.com/maxim-smirnov/gree-wifimodule-firmware/blob/main/362001062107/ota_sdkshell-5525215474150399862.md?plain=1#L1
(obviously use your own model code)
The thing is that there are few servers and they can contain different things. You need to check them one by one until you find sth:
https://github.com/maxim-smirnov/gree-wifimodule-firmware/blob/main/firmwareFetch.py#L77

[marcinlubojanski]

@mkaluza
Unfirtunately it seems that there is no firmware for my model (362001066763). Tried to seach both manuall and via firmwareFetch.py :/

[mkaluza]

@marcinlubojanski
yes there is. Though the fetch script has/had an error that makes it fail if the code directory does not exist - so create it first manually and run again. It worked for me:

Or just use one of the urls above :)
once you have the file, look for SetTem - you'll find all the names.

[marcinlubojanski]

@mkaluza And look for the names with "strings" command ?
I have fund funny stuff :

"<formula1>
  <team name="McLaren">
    <driver>
      <name>Kimi Raikkonen</name>
      <points>112</points>
    </driver>
    <driver>
      <name>Juan Pablo Montoya</name>
      <points>60</points>
    </driver>
  </team>
</formula1>
"

and

" "CreateDate": "2023-07-13 06:46:44",
  "commProtVer": "",
  "desc": "solve Poland problem",
  "forcedUpgrade": 0,
  "r": 200,
  "url": "http://test.grih.gree.com/wifiModule/image/17838/786432","

But I do have lot of variable names to test as well :D

[mkaluza]

@marcinlubojanski
lol :D "solve Poland problem" sounds scary though... but anyway, strings, notepad, whatever you like - they are clustered in one place, so you get one, you get all of them. Though I see they appear more than once in the firmware - unlike in mine. Those look promissing:

EnvironmentTem
AirInTem
AirOutTem
LowPressureTem
HighPressureTem

In general - *Tem* :)

[marcinlubojanski]

Unfortunately almost all those "new" variables return 0. I have found additional water temperature sensor which I do not use and variables whenever defrost or heater is on. But nothing really valuable like external temperature :D
Anyway in the meantime I have build ESP32 + 5 Xiaomi BT temperature sensors + supla FW. I have temperature for all rooms and external. All goes to Grafana and is also used in my script to control heating :)

[mkaluza]

@marcinlubojanski oh well... was worth a try...
I just bought RPi5 as a base for home automation (and probably a home server, those specs are rather amazing...) and was thinking about Tuya sensors, but those from Xiaomi look ok/inexpensive as well. I could use humidity readouts...
Though I very much do not want Grafana... it sucks balls deep - it sucked when I had my first take at it few years ago and it still does... but probably there's nothing better anyway :/

[mkaluza]

@marcinlubojanski so there is another way :D I recently plugged into it's internal communication bus :D
https://github.com/mkaluza/gree-hacking (that's just a preliminary writeup)
And since then I've found this https://github.com/bekmansurov/gree-hvac-protocol - so I'm not the only one :P
But unfortunately they have different electrical characteristics - mine has 0 - 30V - 55V "logic" leves and constant frame length, that other one has more 'normal' parameters but variable frame length.... So probably you need to have an oscilloscope to hack it (safely).

But about your stuff - I also got Xiaomi sensors and they work fine. Are you talking to them directly from raspberry? or is that Supla a complete system? (yeah, I will read about it later)

The interesting thing about those params from the firmware is that some of them are not there - there is no 'Lig', 'time' and 'hid' to all of which the AC responds... so maybe there are more... :)

[marcinlubojanski]

@mkaluza at least my Gree should have modbus interface, but I don;t have hardware for it (nor any knowledge).
As for the Xiaomi sensors - I have changed the firmware on them to Supla, then connected to ESP32 which runs small code that gathers data and upload to Supla. Then on supla site/app you create unique link for each sensor and this can be then used in any script (there is no need to integrate with supla anyhow).
More details in polish over here: https://forum.supla.org/viewtopic.php?t=11193
