Prototype in development
When everything goes dark, Haven stays on.
A small hub for your home that keeps an offline library, push-to-talk voice and family texting across town running, with no internet and no cell service.

Why Haven
Storms, outages, overloaded towers. The moment you most need information and each other is the moment the network disappears. Haven keeps the essentials inside your own home: a library, a voice channel and a family text line that don’t depend on anyone else’s infrastructure.
What it does
Everything the household needs, served from home.
The hub runs the library, the AI, push-to-talk and weather alerts. Pocket radios carry texts and locations across town. None of it touches the internet.
Push-to-talk at home
Phones talk like walkie-talkies through the hub. Voice never leaves the house.
Ask Haven AI
Any phone on the network can ask questions in a browser. No AI app to install.
Family messaging across town
Pocket radios send texts and GPS locations over a LoRa mesh network and pair to each phone by Bluetooth. No cell service needed. Range depends on terrain.
Weather alerts to every radio
The hub listens to NOAA Weather Radio and forwards alerts to every family radio, as an extra warning alongside official ones.
Keeps running through an outage
A UPS board with four 18650 cells keeps the hub up when the power cuts out. The router runs from a USB-C power bank, and the roof relay has its own solar panel and battery.
How it works
One hub at home. A radio for everyone who leaves.
- 01
At home, the hub is the network
The hub plugs into a Wi-Fi router and serves the library, Haven AI, push-to-talk and weather alerts on its own HavenHub network. Phones just open haven.lan in a browser.
- 02
Across town, radios carry the message
Everyone who leaves carries a pocket radio paired to their phone by Bluetooth. Texts and GPS positions travel over the LoRa mesh, through a solar relay on the roof, back to the hub radio.
- 03
In an outage, it keeps going
The hub runs on its UPS battery and the router on a power bank. The roof relay has its own solar panel and battery, and the radios run on theirs.

Inside the hub
Inside the Haven hub
Small enough for a bookshelf.
The hub cage is 116 × 104 × 69 mm. It is 3D-printed and open on all four sides, so air moves freely and every port stays within reach.
Built from parts you can name.
A Raspberry Pi 5 does the work. A Geekworm UPS board and four 18650 cells keep it running when the power cuts out. Every part is off the shelf and listed in the build guide.
Every part has a job.
Ten parts, each off the shelf or 3D-printed, each with one job to do.

Range across town
A relay on the roof stretches the family mesh across town.
Concept scene, not product footage
Everyone who leaves the house carries a card-sized radio that pairs to their phone by Bluetooth and sends texts and GPS positions over a Meshtastic LoRa mesh. No towers and no SIM cards.
A solar node on the roof is set to Meshtastic's ROUTER role: a fixed, well-placed relay that passes messages between the hub radio and the radios out in town. It runs on its own panel and battery, so it keeps relaying when the house loses power.

Straight answers
What Haven is, and what it isn’t.
Preparedness gear is full of big promises. We’d rather tell you exactly where the edges are.
Voice is for home.
Push-to-talk works within the router’s Wi-Fi. Across town, it’s texts and locations over the mesh.
Range depends on terrain.
Hills, buildings and walls shorten LoRa range. The roof relay helps, and we’ll publish measured distances from our tests.
Weather alerts are a backup.
The hub forwards raw alert codes from NOAA Weather Radio. Treat them as an extra warning, never a replacement for official alerts.
The hub’s AI is small.
A Raspberry Pi runs a ~3B-parameter model slowly. If test answers are too slow, AI stays on the phones instead.
Certified radios, included antennas.
The radios are FCC-certified. A different antenna can change a device’s certification, so Haven keeps the antennas each radio comes with.
Content you’re allowed to keep.
Wikipedia-family files and OpenStreetMap maps ship with attribution, and every AI model’s license is checked first.
Built in the open
Proven on the bench before it ships.
Haven is being built in two stages, and every claim on this page has a test behind it. Both build guides are public, down to the last command.
Stage 1
Bare minimum prototype
A Raspberry Pi hub and two pocket radios that prove Haven’s three core claims with no internet and no cell service.
- Shared offline library
- Walkie-talkie at home
- Family messaging across town
Stage 2
Full working prototype
The complete Haven Home system: whole-house Wi-Fi, a 1TB library, AI on the hub, a solar roof relay, four family radios, weather alerts and battery backup.

Questions
Good questions, plain answers.
Want the full detail? Every part and command is in the build log.
Does Haven need internet or cell service?
No. The hub makes its own Wi-Fi network and serves everything from inside your home, and the family radios talk to each other over their own LoRa mesh. Every test in the prototype plan is run with the home internet unplugged.
What works where?
At home, on the HavenHub Wi-Fi: the library, maps, Haven AI and push-to-talk voice. Across town, over the mesh: texts, GPS locations and weather alerts. Voice does not travel over the mesh.
How far do the radios reach?
It depends on terrain, buildings and how high the relay sits, which is why the kit includes a solar relay for your roof. We’ll publish measured distances from the prototype tests, with the relay up and with it unplugged.
What happens when the power goes out?
The hub keeps running on its UPS board and four 18650 cells (about 48 Wh), and the router runs from a USB-C power bank. The roof relay has its own solar panel and battery, and each radio has its own battery. When power returns, every service comes back on its own.
Which apps do we need?
For the library and Haven AI, just a web browser. For push-to-talk, a free Mumble app (Mumla on Android). For the radios, the free Meshtastic app. Organic Maps is a good offline map app to pair with the hub’s map downloads.
What’s in the library?
English Wikipedia with pictures, the WikiMed medical encyclopedia and Wikivoyage, plus offline map files for your state that phones can download from the hub. It all lives on a 1TB SSD.
Do the radios need a license?
They’re FCC-certified devices for the license-free 915 MHz band in the US. Keep the antennas they come with: a different antenna can change a device’s certification.
When can I buy one, and what will it cost?
Haven is a prototype in development, so pricing isn’t set yet. Join the waitlist and you’ll hear first, along with the test results.
Can I build it myself?
Yes. Both prototype guides are public, with wiring diagrams, printable enclosure drawings, every command and the tests that prove it works.
