See your tank level on the display and your phone
The TLC2404LS-WL combines non-contact water level sensing with an LCD monitor. View tank level, room temperature and time, check water data in Tuya Smart or Smart Life, and receive audible alerts at your chosen thresholds.
Everyday LCD monitoring
See water level, room temperature and time on the display.
App access
The monitor shares tank data with Tuya Smart or Smart Life over 2.4 GHz Wi-Fi.
Wireless sensor link
Readings reach the monitor over 433 MHz RF; both units need power.
High and low level alerts
Hear the buzzer when water rises above or falls below your thresholds.
What you need to get started
- 2.4 GHz Wi-Fi at the monitor and internet access for remote monitoring.
- A 5 V DC supply for both sensor and monitor.

Questions to help you choose
Does the tank need Wi-Fi coverage?
The sensor uses 433 MHz RF to reach the monitor. Wi-Fi coverage is required at the monitor.
Does the sensor work without a power cable?
The data link is wireless, but each unit needs a 5 V DC supply.
Can it switch a pump directly?
Pump automation needs a separate compatible smart controller rated for the pump's electrical load.
