The RainPoint Smart+ Garden Irrigation System Hub is designed to be the central control unit for your smart garden, offering comprehensive monitoring and intelligent irrigation management. More than just a display, it acts as the brain of your system, connecting various sensors and water timers to provide an integrated and efficient watering solution.

Function Description

The Hub serves as a Wi-Fi display and control center, integrating data from multiple smart garden devices to provide a holistic view of your garden's conditions and irrigation schedule. Its primary function is to facilitate smart watering, ensuring your plants receive the right amount of water at the right time, thereby conserving water and promoting healthier growth.

The device displays a wealth of information on its LCD screen, including a weather forecast for reference, which can help in making informed watering decisions. It features a freezing point alert to protect your plants from frost and a Wi-Fi signal indication to ensure stable connectivity. The hub shows the next watering plan time and the remaining watering time, keeping you updated on your irrigation schedule. It supports multiple smart garden zones, each representing a water timer outlet, allowing for customized watering across different areas of your garden. A watering reminder ensures you don't miss any critical irrigation events.

Battery levels for both the water timers and the hub itself are displayed, prompting you to replace batteries when necessary. The hub also integrates indoor thermo-hygrometer readings, providing information on the temperature and humidity within your home. For outdoor conditions, it connects to external sensors to display outdoor thermo-hygrometer data, soil moisture levels, and rainfall information, if these sensors are connected. The display also indicates the UV level, current time, and calendar, along with the highest and lowest temperatures for the day.

A key feature is its ability to display sensor data. If external sensors are connected, the screen will show their readings; otherwise, it will display data obtained from the network. The hub also provides an indoor comfort level indicator, categorizing the environment as dry, comfortable, or wet based on humidity and temperature. It can initiate a rain delay, automatically pausing irrigation plans if rain is detected or forecasted. Water usage is tracked and displayed, helping you monitor consumption. Manual watering can be initiated directly from the hub for a chosen zone, providing flexibility for immediate needs. The smart backlight mode adjusts the screen brightness for optimal visibility.

Maintenance Features

The RainPoint Hub is designed with ease of maintenance in mind, primarily focusing on power management and connection stability.

Power Management:

The hub primarily uses a 5V DC adapter for power, which is included. Batteries (3 x AA, not included) are for backup power only, especially important for maintaining Wi-Fi connection.
It is crucial to use the correct power adapter for the hub and all connected electronic equipment to ensure proper functioning.
If the device is offline, checking if the battery is fully charged or if the power supply is normal is the first step.

Connection Stability:

Wi-Fi Connection: The hub requires a 2.4GHz Wi-Fi network to operate normally. If you have a dual-band router, ensure your phone is connected to the 2.4GHz network during setup.
Device Proximity: For successful pairing, the hub and connected devices should ideally be within 10 feet (3m) of each other.
Troubleshooting Disconnection:
- Replacing batteries in sensors and sub-devices often resolves connection issues.
- Distance or physical obstructions (resistance) can cause loss of connection between sensors/sub-devices and the hub. Ensure devices are within range.
- Verify that the Wi-Fi network is stable and functioning correctly.
- Restarting the device and attempting to reconnect can resolve temporary issues.
- If the working Wi-Fi network needs to be changed, press and hold the Wi-Fi button on the hub and re-enter new Wi-Fi information in the app.
Outdoor Sensor Battery Life: Outdoor sensors may experience reduced battery life if they are at the edge of their range. Using fresh Alkaline batteries is recommended, as battery life is typically over 12 months with them. Mixed use of old and new batteries, or using Carbon/rechargeable batteries, can significantly reduce battery life. Check for leaking batteries, which can damage the outdoor sensor.
Network Signal: A poor network signal or being too far from the router can cause the device to go offline.

General Care:

To ensure accurate displays, keep the devices away from freezing temperatures, direct sunlight, rain, or any heat sources. This protects the internal components and maintains the accuracy of temperature and humidity readings.
