What does signal strength (RSSI) mean, and how do I know if it's good?

RSSI stands for Received Signal Strength Indicator. It measures the strength of a wireless signal between your device (such as a fixture or gateway) and the network it's connected to.

RSSI is typically expressed as a negative number—the closer the number is to zero, the stronger the signal.

General RSSI Range Guidelines:

• -30 to -50 dBm: Excellent signal

• -51 to -65 dBm: Good signal, stable connection

• -66 to -75 dBm: Fair signal, may experience minor issues

• -76 to -90 dBm: Weak signal, likely to cause connectivity problems

• Below -90 dBm: Very poor or unusable connection

For reliable performance, especially in mesh networks like WAC-Mesh, it's recommended to maintain an RSSI of -65 dBm or better between devices and gateways.

You can check the RSSI for your devices in the Network Status section of the MyWAC app.
