Tuya wifi Water Level Monitor Ultrasonic with Monitor Level Display ME201R

The Moray ME201R system uses both RF433 MHz and 2.4 GHz Wi-Fi for connectivity. The different frequencies serve different parts of the system to maximize range and functionality. 

How the Connectivity Works

• Sensor to Gateway (RF433 MHz): The outdoor sensor unit communicates wirelessly with the indoor gateway/display unit using a robust RF433 MHz signal. This connection offers a long range of up to 500 meters (approx. 1640 feet) in open spaces, allowing the sensor to be placed far from the main house or Wi-Fi router.
• Gateway to Router (2.4 GHz Wi-Fi): The gateway unit, which has the LCD display, connects to your home's 2.4 GHz Wi-Fi network. This link enables the gateway to send data to the internet and the Tuya Smart Life app on your smartphone, providing remote monitoring and alerts. 

In summary, the RF433 connection is essential for the long-range communication between the sensor and the indoor display unit, while the Wi-Fi connection is used for smart features and remote monitoring via the app.
