[TS0601 / _TZE284_zpvusbtv] Tuya TS0601 two-gang (ZN2S-RS02E) - indicator_mode should be enum; add backlight %, backlight switch, and colors #29607
Description
What happened?
The current Zigbee2MQTT support for Tuya TS0601 two-gang switch (ZN2S-RS02E / _TZE284_zpvusbtv) handles the datapoint indicator_mode as a boolean (on/off).
However, this device exposes it as an enum with three possible states according to Tuya IoT logs and API data (image1.jpg)
{"1":"Switch 1","2":"Switch 2","7":"Timer 1","8":"Timer 2","13":"Master Switch","14":"Restart Status","15":"Indicator Status","16":"Backlight Switch","19":"Delay-off Schedule","101":"Child Lock","102":"Backlight","103":"ON Color","104":"OFF Color"
Because of this wrong mapping, the indicator LED mode can’t be controlled correctly — setting it to "off" or "switch_position" is ignored, and Z2M only treats it as boolean.
What did you expect to happen?
indicator_mode should support all three modes:
• "off" → completely turns off all LEDs, regardless of relay states.
• "on_off_status" → LEDs reflect relay state.
• "switch_position" → LEDs indicate button position.
Also, the converter should expose:
• backlight (DP102) as a number 0–100.
• backlight_switch (DP16) as a boolean.
• on_color / off_color (DP103/104) as enums.
How to reproduce it (minimal and precise)
1. Pair the device with Zigbee2MQTT 2.6.3.
2. Try to send via MQTT: {"indicator_mode":"off"} The command is ignored because Z2M expects a boolean.
3. If you check via Tuya IoT Device Log, you can see DP15 correctly changing to "off", "on_off_status", or "switch_position".
4. Also, note that sending: {"backlight":10} has no effect, since DP102 is not exposed.

When sending { "indicator_mode": "ON" } → accepted (boolean mapping)

{"leave_count":0,"messages":2524,"messages_per_sec":1.0516,"network_address_changes":0}✅ Working features:
• Master switch (DP13)
• Switch L1 (DP1)
• Switch L2 (DP2)
• Backlight switch (DP16)
• Power on behavior (DP14)
• Child lock (DP101)
• Color control ON/OFF (DP103/104)
❌ Issues:
• indicator_mode handled as boolean (should be enum)
• backlight percentage (DP102) missing
• MQTT direct commands (e.g., {"state_l1":"ON"}) revert immediately to OFF, while working fine from Z2M UI (possible optimistic update mismatch)
• Missing indicator_mode options in exposes.
💡 Proposed fix (JS patch for tuya.js)

✅ Tested and confirmed
All these datapoints and modes were verified through Tuya IoT Console → Device Log and DP list, and cross-checked via Zigbee2MQTT external converter.
Tested using MQTT commands and verified correct LED and backlight responses.
