@Fred_Schaap @keke @ozi1024 please ensure you are on v1.2.1 and send diagnostic report. @Fac3 Usually ACs should be discovered by default. By adding the ACs by IPs you are just forcing the app to create a device with hardcoded IP. It helps bypass issues with discovery, when the Homey and ACs are in different IP subnetworks, but in case app cannot communicate with AC it will not help. Try also send diagnostic report, I’ll take a look. Mention you nickname or describe the problem in the message **2all. Avoid firmware updates of WiFi module** ---

Hi everyone, I am experiencing the same issue with my Gree units and wanted to share my observations. After updating to the official **v2.12 (v2.12+)** firmware, the connection to **two of my Gree Smart One units completely dropped in Homey** (showing offline/timeout status), while my third unit, which **has not been updated** , continues to work flawlessly and stably through Homey. (Also, a new feature appeared in the official Gree app on the updated units: the ability to turn the device beep sound on or off). While researching online, I came across the following technical explanation that perfectly describes the issue: > _The Gree firmware 2.12 (v2.12+) software update refreshes the operation of the air conditioners’ built-in Wi-Fi module. This version improves the security and stability of the cloud connection, but it closes the local UDP port (port 7000), causing smart home systems (like Home Assistant) to lose local connectivity with the air conditioner. The update has no effect on the mechanical cooling or heating performance of the AC._ Similar issues have been reported in other smart home communities (such as Home Assistant) following the latest Gree updates. Does anyone have any ideas, or is there any workaround / alternative method expected from the developers to restore local communication or introduce cloud API support? ---

My Gree GUD100PHS1/A-S U-Match (commercial/VRF, behind an XE7A-24/HC wired zone controller) never worked with this app — showed unavailable, same symptom others here have reported for similar commercial-class units. Turns out these units don’t use the consumer Gree+ cloud MQTT broker (`mqtt-eu.gree.com:1984`) at all — which is what this app, and every open-source Gree library I found, assumes. After reverse-engineering the real GREE+ app’s own traffic: 1. It calls an endpoint that’s in no reference implementation: `POST /App/QueryOnline` (same regional host as login, e.g. `eugrih.gree.com` for Europe), passing the device MAC(s). Returns, per device: `{ "svr": "eu05.as.gree.com:16385", "isSSL": false }` 2. That host:port isn’t an MQTT broker — it’s a bare TCP socket, one request at a time: open, write one newline-terminated JSON line, read one back, close. No subscribe, no session. 3. The JSON envelope (`pack`/`i`/`cid`/`uid`/`tcid`/`t`) is identical to the consumer MQTT message shape, and `pack` uses the same AES encryption (CipherV1/CipherV2). Only the transport differs — login, ciphers, property codes all carry straight over. One more thing specific to this hardware class: it can show up twice in the device list under the same key — one MAC ending in `00`, one not. Only the `00` one responds to commands. Built a driver against this and it’s been running solidly. @aivus — happy to share the discovery + raw-socket transport code if you want proper commercial/VRF support in the official app, rather than everyone with this hardware having to DIY it. Let me know. Hope this helps whoever else is stuck on a commercial unit. With thanks to my friend Claude 😉 ---

Hi, I have a Tosot CTS-24R cassette unit (7kW, Gree-manufactured) that I managed to add manually via IP address (after checking ‘skip UDP scan’, since the automatic scan couldn’t find it). After adding it, however, the device stays permanently ‘unavailable’/‘no response’, even after restarting the app. Context: - Another Tosot unit (3.5kW, upstairs) already works fine with the same Gree app. - The GREE+/TOSOT+ phone app works completely normally for this 7kW unit. - Homey and the AC are on the same subnet/SSID (2.4GHz), Client Device Isolation is off. - I’ve sent a diagnostic report from the Homey app. Diagnostic code: 1cf58b53-cd83-4915-b1a5-388e95c55bc1 Could you take a look at what’s going wrong here? I suspect a firmware/protocol difference between this unit and the working one upstairs, but I don’t know how to investigate this further. Thanks in advance! @aivus ---

Hello there, As it was noticed by many of you, latest firmwares of Gree WiFi module dropped/restricted direct(local) communication. I’m intermittently working on the Cloud integration, so app can work with the AC in the similar way as the EWPE Smart/Gree+/etc apps work. I assume that _will not_ be done this year. * * * For everyone who is trying to add AC by IP address and sees “No response”/“Unavailable” I just want to repeat: By adding the ACs by IPs you are just forcing the app to create a device with hardcoded IP. It helps bypass issues with discovery, when the Homey and ACs are in different IP subnetworks, but in case app cannot communicate with AC it will not help.
