Customer Questions & Answers
What advantages does the SONOFF DW2 RF wireless sensor offer over wired door and window sensors?
The SONOFF DW2 RF removes the need for cables, making installation easier and allowing flexible repositioning. This reduces labour and installation costs, although wired sensors usually offer greater immunity to interference and require less battery maintenance. The choice depends on the balance between flexibility and resistance to RF interference.
What are the dimensions, materials and weight of the SONOFF DW2 RF sensor, and what is included in the package?
The main sensor measures 70 x 31 x 19 mm and the magnet 44.5 x 15 x 10.5 mm; both are made from durable ABS plastic. The total weight is approximately 45 g. The package includes the sensor, magnet, adhesive tape and manual. The battery (CR2032) must be purchased separately in some cases.
Which systems or devices is this sensor compatible with, and what are the requirements for correct operation?
The DW2 RF operates at 433.92 MHz and requires a compatible SONOFF RF bridge (such as SONOFF RF Bridge 433) to integrate with eWeLink applications. It is not directly compatible with assistants such as Alexa or Google Home unless the SONOFF bridge and intermediary platforms are used. It should be installed on doors/windows made of non-metallic material to avoid signal attenuation.
What wireless communication range does the sensor have, and what factors can affect its performance?
The typical RF communication range is up to 50 metres in open spaces and 10 to 30 metres indoors, depending on obstacles such as walls and devices that generate RF interference. Metal structures or multiple walls can reduce the effective range.
What maintenance does the sensor require, and how can common faults such as missing notifications be diagnosed?
The main maintenance is periodic replacement of the CR2032 battery every 1-2 years, depending on use. If notifications are missed, check the battery level, distance and obstructions from the bridge, and the condition of the adhesive/mounting. Most faults are due to a flat battery or excessive distance/interference.
Do I need any additional device for the SONOFF DW2 RF sensor to work?
Yes, the SONOFF Bridge RF433MHz is required for the sensor to work correctly.
Are batteries included with the sensor?
No, batteries are not included in the package and must be purchased separately.
How do I install the sensor?
Installation is very simple and does not require tools, as it is fixed with the included 3M adhesive on the back.
Can I link a camera to see who opens the door or window?
Yes, the sensor allows you to add a camera or an old smartphone to see who is accessing your home in real time.
How long does the sensor battery last?
The sensor has low power consumption that can extend battery life up to 2 years.
