Before installing EnOcean devices, conduct a site survey to assess optimal placement of sensors and receivers.
To conduct a site survey:
- Obtain a floor plan of the space.
- Mark the locations of fire protection walls, staircases, elevator shafts, restrooms, server rooms, and any other areas of the building that may block radio signals.
- Using a compass, draw a circle around each proposed receiver location (where you plan to install an O3 Edge. The circle represents the effective radio signal range. Each circle should cover approximately 20 m (66 ft) and overlap as little as possible with other circles.
EnOcean sensors should be located within a 10 m (33 ft) radius of the receiver. Ideally, the wireless signal should have an unobstructed line-of-sight path to the receiver. It should not cross any of the marked areas. For more details, see https://www.enocean.com/en/support.
As sensors are installed, conduct field tests with a handheld radio signal strength meter at each receiver location and verify that the signal is properly received. In some cases, you may need to move the sensors, change antenna positions, or add repeaters to achieve the desired result. As each receiver location is verified, record the signal strength measurements on the floor plan.
