Why? According to the other integrations, it should work as a simple on/off device with a standard cluster.
It should actually work out of the box with the stock SmartThings Zigbee Switch driver:
Zemismart ZN-LRL1E Zigbee Technical Details
The Zemismart ZN-LRL1E (also marketed as a high-power 20A/30A boiler/water heater switch) is a Tuya-based device that presents itself on the Zigbee network as:
- Model ID:
TS0001 - Manufacturer:
_TZ3000_ubrvwoxv
It is fully supported in Zigbee2MQTT under the standard TS0001 definition (no external converter or custom quirk is required). It is treated identically to other TS0001 1-gang switches.
Endpoints and Clusters (Typical for this device class)
These devices use a very standard, minimal Zigbee implementation:
- Primary (and usually only) Endpoint:
1 - Profile ID:
0x0104(Home Automation) - Device Type: Typically
0x0000(On/Off Output) or0x0051(Smart Plug) depending on exact firmware
Key clusters on Endpoint 1:
| Cluster ID | Name | Type | Purpose |
|---|---|---|---|
0x0000 |
Basic | Input | Device identification, manufacturer info |
0x0003 |
Identify | Input | Identification/locating |
0x0004 |
Groups | Input | Group membership |
0x0005 |
Scenes | Input | Scene support |
0x0006 |
On/Off | Input | Main control — state, on/off/toggle, power-on behavior |
0x000A |
Time | Input/Output | Time synchronization (common on Tuya devices) |
0x0019 |
OTA | Output | Over-the-air firmware updates (if supported) |
No energy monitoring / Metering cluster (0x0702) on this variant (unlike some _TZ3000_... TS0001_power models).
