Optional off-grid companion
Small radios that talk to each other, no towers, no internet, no monthly bill
Mesh networking is a set of small LoRa radios that relay short text messages and location pings from node to node across your property, or between your group, when there’s no cell coverage. It’s an optional add-on to Radiant Vault, not a replacement for it.
How it works
Each node relays for the next
A question leaves the handheld, hops through the solar repeater, and lands at the Vault. The barn sensor reports the same way.
You carry or place a small radio node. It pairs to your phone or plugs into your Vault.
You send a short text or location ping. The node broadcasts it over LoRa radio.
Nearby nodes hop the message along until it reaches its destination, no towers involved.
This is a texting and telemetry medium: short messages and small data points. It cannot stream, browse, or move files, images, or large documents.
Use cases
What people actually use it for
Family check-ins
Send a short text or location ping to anyone else carrying a node on your property.
- ◆Works across a large property with no cell signal
- ◆Each node can share its last known position
- ◆No monthly bill, no carrier account
Outbuilding monitoring
Watch solar, water, and power status from a barn, well house, or detached shop.
- ◆A sensor node reports temperature, battery, or tank level
- ◆Alerts route back to the main node near your Vault
- ◆Solar-powered repeaters run indefinitely off small panels
Gate & perimeter alerts
A node at a gate or fence line can push a text alert when triggered.
- ◆Simple motion or contact sensors trigger a mesh message
- ◆No wiring back to the house required
- ◆Pairs with your Vault's local automation, no cloud service involved
Group coordination during an outage
Coordinate with neighbors or family spread across a wide area when the grid is down.
- ◆Text messages hop node to node, no towers needed
- ◆Useful range is realistically kilometers, not miles of guaranteed coverage
- ◆More nodes in range means better relay coverage
Texting your Vault's AI remotely
Experimental: send a short question to your Vault's AI from a handheld node and get a short answer back.
- ◆Answers are capped at roughly 200 characters and may arrive in a few chunks
- ◆Expect seconds to minutes for a reply, not an instant chat
- ◆Best for terse questions, not research or long conversations
An honest range section
Real-world range, not marketing numbers
Range depends entirely on terrain and antenna height. We’d rather tell you the realistic figures than the record-setting ones.
Suburban / wooded terrain
1–3 km
With stock antennas, node to node.
Open water / line of sight
5–10 km
With an external antenna and elevation on one end.
Record line-of-sight test
331 km
A community stunt result. Not a planning figure. Don’t expect anything close to this on your property.
Mesh radio is not a substitute for a licensed emergency radio or a 911 lifeline. In the US, this hardware operates on the 915 MHz band under FCC Part 15; other regions use different bands and duty-cycle rules.
Every property is different
Talk to us before you buy nodes
Node count, repeater placement, and whether a solar-powered relay makes sense for a detached structure all depend on your specific layout. We offer a short design consultation to work through it before you spend anything on hardware.
