How Many Meshtastic Radios Does a Family Need?

A family needs at least two Meshtastic radios, and in practice one for each person you'd need to reach when phones are down. Many households add a home radio mounted high on wall power so the house is always on the mesh. If home, school and work are farther apart than your radios can reach, add a relay placed somewhere high.

Why is two the minimum?

A Meshtastic radio sends messages to other radios. One radio by itself has nobody to talk to unless you live near an active community mesh, and even then you can't count on strangers' radios being on when you need them. Two radios on a shared private channel give you a working link you control, and they let you test range and settings around your own neighborhood before you rely on them.

That's why we discount the second Walkie Textie automatically when you put two in the cart, and why the WisMesh Pocket v2 comes in a 2-pack. If you're new to how the radios work, start with our explanation of what Meshtastic is.

How do you figure out the right number?

Count the people who would be apart during an outage and need to reach each other. For most households that's each adult who leaves the house for work, and each child old enough to be somewhere on their own, like school, practice or a friend's house. A toddler who is always with a parent doesn't need a radio of their own.

Then think about who uses what. An adult who always carries a phone may be happy with a small screenless radio. A teenager might want a radio with a screen. An older parent or a child without a phone is better served by a radio like the LILYGO T-Deck, which has its own screen and keyboard. Every Meshtastic radio on the same region and channel talks to the others, so mixing models is fine.

Why add a home radio?

A radio that lives at the house solves a few problems at once. Put it in an upstairs window or attic, plug it into USB power, and it stays on the mesh around the clock. Family members heading home can reach the house before they arrive, and because the home radio is higher than a radio in a pocket, it also relays messages between family members who couldn't reach each other directly.

A home radio is also a natural rally point in your communication plan. If you've written a PACE plan, Meshtastic often fits as the alternate or contingency method, and a home radio gives everyone a fixed place to send a check-in.

When do you need a relay?

Test before you buy more. The Walkie Textie averages about half a mile between two units, and height, terrain, buildings and trees change that a lot. Try sending messages between home and the places your family actually goes. If they get through, you're set. If school or work is out of reach, a relay placed high between those places can close the gap.

The Atlavox Beacon Solar Meshtastic Node puts a radio, solar panel and antenna in one frame that you mount high and leave. Our guide on maximizing Meshtastic range covers what to try before adding hardware.

A typical setup for a family of four with two working parents and two school-age kids might look like this.

• Four handheld radios, one per person
• One home radio in an upstairs window on USB power
• A solar relay only if testing shows a gap to school or work

Common questions

Can we share one radio between two people?

If they're always together, yes. The point of a radio is reaching someone who is somewhere else, so anyone likely to be apart from the rest of the family during an outage should carry their own.

Do all of our radios need to be the same model?

No. Different Meshtastic radios work together as long as they're set to the US region and share your family's channel. Pick each one based on the person carrying it.

Can neighbors or relatives join our mesh?

Yes, and their radios help relay messages for everyone. Keep family messages on your own private channel, and you can still share the public channel with neighbors for general coordination.

What should we do once we have the radios?

Set them up together, practice sending messages, and write down who contacts whom and when. Our guide to making a family emergency communication plan walks through that part.

A pair of Walkie Textie radios is an easy way to start, and the second one is discounted automatically.
