L1 and L2 led strip not working in v3.7.1 onwards (v3.6.0 seems ok to me)

[Kydonakis]

Since v3.7.1 (in 3.7.2 and 3.7.3), I get errors with my L1 and L2 led strips. The last working (for me) version is 3.6.0.

The problem is that the devices seem unable to load in home assistant while they work perfectly through the ewelink app.

By checking the logs and device diags I managed to stop some differences:

Relevant home assistant logs pointing to some error (L2 led strip):

2024-05-10 20:27:41.227 DEBUG (MainThread) [custom_components.sonoff.core.ewelink] 10013f4d9a UIID 0137 | {'bindInfos': {'alexa': ['e/2'], 'ifttt': ['e/f']}, 'version': 8, 'init': 1, 'fwVersion': '1000.2.1050', 'ssid': '/', 'bssid': '/', 'switch': 'off', 'colorR': 151, 'colorG': 241, 'colorB': 145, 'mode': 1, 'bright': 20, 'light_type': 1, 'NO_SEND_TO_APP': 0, 'lineSequence': {'1': 'b', '2': 'g', '3': 'r'}, 'timeZone': 2}

From the integration diagnostics I see for one of the L2 led strips:

        },
        "model": "L2",
        "online": true,
        "local": null,
        "localtype": null,
        "host": null
      },

My current setup is

Core 2024.5.2
Supervisor 2024.05.1
Operating System 12.3
Frontend 20240501.1

By the way, the integration is working in auto mode, however, when I changed to cloud (n 3.7.3), no progress was made. On the contrary, no devices were loaded at all.

Any ideas?

Cloud auth don't work for you. TimeoutError - probably you have problems with Internet.
This device don't work for you in local mode.
