Is it possible to support midea heat pump controller KJRH-120F (device type C3)? #79

It is recognized by midea discover as type 'C3': {'name': 'net_c3_0074', 'ssid': 'net_c3_0074', 'ip': '192.168.1.173', 'port': 6444, 'id': '...', 'version': 3, 'token': '...', 'key': '...', 'type': 'c3', 'sn': '0C3310171H120F22214100074WC9N', 'model': 'H120F', 'support': False, 'run_test': True}

It already partially works with your integration when I select type "CF" heat pump. On/Off works but setting the temperature doesn't work, so I guess the attributes are different for type C3.

Could you send your username and password of MSmartHome (or NetHome Plus?) to georgezhao75@gmail.com so that to get the protocol plugins for that device.

Thanks for your help, I'll send you my credentials. I have a relabled midea device by another distributor, so you have to use a different app Comfort Home. But it's essentially a MSmartHome clone and seems to communicate via the midea cloud. So I hope it's sufficient to get the protocol plugins you need. MSmartHome doesn't work because it expects a different ssid "midea_c3_xxxx" instead of "net_c3_xxxx". NetHome Plus doesn't work because it doesn't support the device H120F.

Comfort Home does not work in my Android emulator, I'll find another way.

It's weird, I did't found any device bound to your account, but the captured message says you have a device. Maybe this device does not support Comfort Home for iOS?

The device should be supported by Comfort Home IOS. In fact this app only supports one device type, C3. However, I also had this "no device" behaviour once on android. Maybe I messed something up in the backend because tried different versions (also downgrade) of the app while experimenting. I'll try to delete the device and pair it again.

Or if the steps are easy to follow maybe I can get you the information you need from the android app?

Hendrik212 commented 2 years ago

Okay, I have now re-paired the device and also changed the name from "Wärmepumpe" to "Heatpump". Maybe the app has problems with German non ascii characters. Hopefully it's now visible in the iOS app.

Nothing changed, even I can't found any devices in captured message.

That's weird, the android app works just fine. Can I somehow extract the info you need or are there too many steps?

Comfort Home app control your device via HTTPS, I guess it detects your device model and downloads a protocol plugin for device, just like MSmartHome and NetHome Plus app, I need to find out the download-url of plugin. Maybe you need to capture the app's message if you can.

Great!

I'll have a look at that and see what I can do.

Hello, I have the same heat pump model : H120F. I was able to install the integration. Unfortunately, it does not read the heat pump correctly. Has anything changed in the topic?
