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.
