The BQ05 (R2) is a smart, remotely controllable WiFi+eWeLink Remote (Bluetooth) compatible watering valve, where the WiFi smart control with eWeLink app is integrated into a watering valve.

SmartWise 5V-32V relays and Sonoff 4CH Pro relay are popular choices for controlling traditional irrigation valves, but now BQ05 is also available as an integrated solution.


The smart valve can be directly attacched to a water tap in the garden. BQ05 has a built-in filter to keep the valve clean from any dirts.



It can be used not only for watering gardens and courtyards, roof gardens, lawns, flower gardens and vegetables, but also for watering in greenhouses.



It has a strong built-in WiFi chip, so you can directly pair it with your WiFi router, no central hub is required to operate it. You can turn on and off the irrigation remotely, through the internet from your mobile phone, and of course, you can also create time-based automations for every day of the week for watering your plants. Just as other Sonoff and SmartWise devices, it also supports loop control, so for example you may set 5 minutes of watering every 5 hours, if you want. Up to 8 schedules are stored in the device, so scheduled on/offs will run no matter if the device is online or its internet connection is lost.

Its durable, waterproof ABS plastic housing withstands the weather and is suitable for long-term use.

The irrigation valve is in the CLOSED state in the event of a power failure, so it can be operated safely in places where a power failure may occur. In the event of a shorter power outage, it will automatically reconnect to the WiFi network, after a long period of power it may need to be reconnected to the WiFi network.

A 5V-9V DC power supply is required for its operation. The irrigation valve comes with a 2-meter USB cable that can provide 5V DC power from either a 1A phone power supply (not included) or a 5V DC battery or powerbank (not included)




It can be attached to the pin with a standard 1-inch female connector or, if necessary, with a 3/4-inch reducer ring (accessory). The lower outlet also has a 1-inch external connector, so sprinkler pipes can be connected, or a hose can be connected with the standard 1/2 '' quick connector.
