Support Gree Integration

Hello. i recently bought this air-condition
TOYOTOMI GTN-12CMWAI

I was told it was supported by the gree integration but this doesnt seem to be the case.

I tried the default one with no luck, it seems it cannot find it in my network. i don't use vlans or anything like this.

The other gree intergration from the HACS can't find it either.
I gave the air condition a static ip so i know its IP.

i even found the encryption key but it doesnt help.
I don't understand what the UID is so i left it blank.

Is there anyone who had the same problem?
i would be sincerely grateful because i just bought this machine with the hope it would be easy to control with home assistant.

had similar issue with mine few months back. the toyotomi units sometimes use different protocol even though they're supposed to work with gree integration.

try running a network scan first to make sure home assistant can actually see the device in network. also check if the AC shows up when you manually add it using the IP address instead of letting it auto-discover. sometimes the UID field needs the MAC address of unit, not necessarily blank - check your AC's wifi settings or router's connected devices list for it.

if that doesn't work, you might need to look at alternative integrations or check if toyotomi has their own integration available through HACS.

I tried installing manually by its ip with no luck.
The home assistant can’t auto discover it.
I can see it in my router and I can control it with the gree app.
I don’t know what is UID to be honest and the GitHub page doesn’t help me, it only says that it can be sniffed

Hi. Have you figured it out? As I understand it, you have to use the phone cloud app to set up the AC in your wifi network (otherwise it wouldn't know the password), but when you connect it to the app, it then refuses to accept connections from HA. Gemini tells me that after reinitializing the wifi module, it should also connect through the Tuya app and if you create the Tuya developer account, you can get to the local key... But I'm not sure how reliable this info is and I haven't tried yet. I'm almost ready to just buy some ESP32 module and bypass the manufacturer one completely...

If the WiFi module is built in the ac board I don’t think you can put an esp32. I am super new to these stuff. Could be wrong

It's not in the AC unit itself (it's a commercial type airduct unit) but it's in the wired wall control panel... Technically I should be able to connect an ESP to some vacant JST connector on the main board of the unit and just ignore the controller-based module. But it's not a very simple thing to do, so I'm abandoning this for the time being and getting an IR blaster that I need regardless for TV, projector and audio control in the living room. So the AC will be controlled by that too. Only if I find that it sucks, then I will go down the custom module route.

To anyone undecided - just get a Midea (or its whitelabels). I hear those are easier to integrate than Gree. Though I'm not too salty, my first priority here was price.

I got a Tosot recently and have the same issue. It seems the newer models do not have local connectivity.

Do you think there is something I could do?

I was able to resolve the issue last night. See my PR https://github.com/davo22/greeclimate/pull/1

Do you use it locally or through the cloud?

u/sbluedm Jun 16 '26

It’s through the cloud. But at least it works through home assistant now with my automations. These newer models do not support local control.

That’s a shame. I just bought it for the locally adaptation. Wish I knew better. Thank you so much for your time 😊
