No control with new Gree AC unit

The problem

Gree GWH09AGAXA-K6DNA4C Pular. This is the second device in this integration. The first device of a different model works normally. The integration finds and successfully adds the device. However, the device is not managed. The logs contain the following errors: Timeout trying to bind to gree device: Device: xxxxxxxxxxxxxxxxx Timeout send state update to: gree-xxxxxxxxxxxxxxxxx Device is unavailable: gree-xxxxxxxxxxxxxxxxx Error fetching gree-xxxxxxxxxxxxxxxxx data: Device gree-xxxxxxxxxxxxxxxxxc is unavailable

stesso problema anche io

I have the same issue, same errors in the log. Same AC model (Pulsar).

[cmroche]

I believe newer units are using a cloud-only protocol. I'm guessing this is the issue you are experiencing, and if true likely means they cannot be supported.

[Machaeon]

@cmroche, newer units using another encryption algo. Custom Gree integration works well with new units: https://github.com/RobHofmann/HomeAssistant-GreeClimateComponent

[alexcotut]

I can confirm what @Machaeon has said. The custom Gree integration works if you set encryption_version: 2 Thank you.

[cmroche]

@Machaeon @alexcotut I am working on adding the newer encryption support, it would help if someone could enable debug logs for greeclimate and send me the scanning, binding and status update sequences. As I do not have one of these newer devices, this will help me confirm it's working.

Edit: Sorry, this is a silly request... how do you do that before the encryption comes in. Perhaps though you could enable it for the custom component you are using? I should be able to work with that instead.

@cmroche I have some logs recorded.
