The PPA109’s wireless signals can reliably traverse a maximum of 4 hops between devices in a project’s mesh network.
A “hop” refers to the signal jumping from one device to another. For example:
PPA109 >> Light (1 hop)
PPA109 >> Light >> Light 2 (2 hops)
PPA109 >> Light >> Light 2 >> Light 3 (3 hops)
After 4 hops, signal attenuation becomes too high, and relay reliability greatly decreases.
Recommendations:
*Design projects so that any device is within 4 hops of a PPA109 or other controller
*Strategically place lights to ensure robust mesh network coverage across the space
*Keep critical control sources like switches/sensors within a 4-hop radius
Following the 4 hop best practice prevents communication breakdowns between devices that are too many relay points apart in the mesh network. This ensures reliable transmission across even large-scale lighting installations.
