Zigbee2MQTT version

1.41.0 commit: unknown

Comments

I have encountered compatibility issues with Tuya RGB+CCT bulbs (model TY-BK-A60, manufacturer _TZ3210_bfwvfyx1) in Zigbee2MQTT. The problem is specifically linked to firmware differences: • Firmware 1.2.5 works correctly with full attribute exposure and control. • Firmware 2.2.2 exhibits missing attributes, erratic behavior, and non-responsiveness to color adjustment commands.

I have tried the following:

Adding custom fingerprints in tuya.js and an external converter.
Analyzing database.db to identify differences between working and non-working firmware attributes.
Modifying lightingColorCtrl configurations to address the unsupported attributes.

Despite these efforts, bulbs with firmware 2.2.2 remain problematic, while bulbs with firmware 1.2.5 work as expected.

I am seeking guidance on:

Whether a firmware downgrade is possible for Tuya devices.
Additional configuration options in Zigbee2MQTT for better compatibility with firmware 2.2.2.
Any planned updates in Zigbee2MQTT or related libraries to address firmware-specific compatibility issues.

Your assistance would be greatly appreciated.

External definition

const { light, commandsOnOff, commandsLevelCtrl, commandsColorCtrl } = require('zigbee-herdsman-converters/lib/modernExtend');

const definition = {
    fingerprint: [
        { modelID: 'TS0505B', manufacturerName: '_TZ3210_bfwvfyx1' }
    ],
    model: 'TS0505B_custom',
    vendor: 'Tuya',
    description: 'Zigbee RGB+CCT light (Custom)',
    extend: [
        light({
            colorTemp: { range: [153, 500] },
            color: { modes: ['xy', 'hs'], applyRedFix: true, enhancedHue: false },
        }),
        commandsOnOff(),
        commandsLevelCtrl(),
        commandsColorCtrl(),
    ],
    exposes: [
        e.light_brightness_colortemp_colorhs([153, 500]).removeFeature('color_temp_startup')
    ],
    configure: async (device, coordinatorEndpoint) => {
        const endpoint = device.getEndpoint(1);
        await endpoint.write('lightingColorCtrl', { colorCapabilities: 29 });
    },
};

module.exports = [definition];

What works with the external definition:

    1.  Pairing: The bulb is recognized as TS0505B with manufacturer _TZ3210_bfwvfyx1.
    2.  On/Off Control: Bulb responds correctly to On/Off commands.
    3.  Brightness Control: Adjusting brightness works as expected.
    4.  Partial Color Temperature Control: Range [153, 500] is recognized, but there is inconsistency for firmware 2.2.2.

What doesn’t work:

    1.  Color Control: Bulbs with firmware 2.2.2 don’t respond to HS/XY color commands.
    2.  Firmware-Specific Issues:
    •   Firmware 1.2.5 works well, but 2.2.2 has incomplete/missing attributes (currentHue, currentX, currentY).
    •   Unsupported attributes during Zigbee commands for firmware 2.2.2.

The external definition significantly improves functionality for firmware 1.2.5, but further work is needed to address compatibility with firmware 2.2.2.

What does/doesn't work with the external definition?

What Works with the External Definition:

1.  Pairing:
•   The bulb is recognized correctly in Zigbee2MQTT as a TS0505B with the manufacturer _TZ3210_bfwvfyx1.
•   The device is successfully added to the network and shows up in the Zigbee2MQTT dashboard.
2.  On/Off Control:
•   The bulb responds correctly to On and Off commands from Zigbee2MQTT.
3.  Brightness Control:
•   Adjusting the brightness level works as expected.
4.  Color Temperature (Partially):
•   The colorTemp values (range [153, 500]) are recognized, but the behavior is inconsistent, especially on bulbs with firmware version 2.2.2.

What Doesn’t Work or Is Inconsistent:

1.  Color Control:
•   Bulbs with firmware 2.2.2 don’t properly respond to HS or XY color commands.
•   The currentHue, currentX, and currentY attributes either don’t update or return incorrect values.
2.  Color Temperature Range:
•   The expected range [153, 500] works only on firmware 1.2.5. Bulbs with firmware 2.2.2 ignore the lower bounds and often misinterpret the colorTemp values.
3.  Firmware-Specific Issues:
•   Bulbs with firmware 1.2.5 work almost perfectly with the external definition.
•   Bulbs with firmware 2.2.2:
•   Fail to respond to currentHue or colorMode.
•   Return unsupported attributes during Zigbee commands (UNSUPPORTED_ATTRIBUTE).
4.  Color Modes:
•   Modes like HS and XY don’t switch correctly on firmware 2.2.2, causing erratic behavior when attempting to change colors.
5.  Attributes Handling:
•   Attributes like currentX, currentY, and colorTemperature don’t sync properly with the external converter on firmware 2.2.2.

Conclusion:

The external definition works well for bulbs with firmware 1.2.5. However, the firmware differences (1.2.5 vs. 2.2.2) introduce inconsistencies, particularly in color and color temperature controls. Additional firmware-specific logic may be required in the external converter to handle these differences effectively.
