Dual Deployment: Repeater + Room Server

Dual Deployment: Separate Repeater and Room Server
The recommended best practice for any fixed site is to deploy two separate devices rather than enabling repeat mode on the room server.
Why Two Devices?
A repeater and a room server have conflicting placement requirements:
 
Device
Ideal Placement
Why
 
 
Repeater
Outdoors, elevated, high external antenna
Maximum RF range in all directions
 
Room Server
Indoors, near power and USB/BT access
Easy administration, configuration, and monitoring
 
Forcing one device to do both jobs means compromising on placement - either the repeater antenna is too low, or the room server is too hard to access for administration.
Recommended Hardware
 
Device 1 (Repeater): Heltec V3 flashed with Repeater firmware + high-gain external antenna (fiberglass omni or directional yagi)
 
Device 2 (Room Server): Heltec V3 flashed with Room Server firmware + stock indoor antenna
Cost
Two Heltec V3 units cost approximately $54 total (roughly $27 each, as of 2026-06-08; pricing is volatile - verify current street price). This is a minimal investment for a significant capability improvement at a fixed site.
When Single-Device is Acceptable
If budget or space constraints make dual deployment impossible, enabling 
set repeat on on the room server is workable - it simply won't perform as well as a dedicated repeater at height. (
set repeat on is the documented MeshCore CLI command for the repeater-hybrid mode; confirm against your firmware's CLI help output.) In that case, do your best to place the device near a window or in an elevated location to improve the antenna's line of sight.
