Before you build

Not sure which sensors I need?

Start with the hub — it covers battery, temperature, GPS and anchor watch on its own. Add a bilge/float sensor if you keep the boat in the water, a shore power sensor if you rely on dock charging, and wireless sensors for engine bays or fridges. Email support@roamdevices.com and we'll spec it with you.

Can I add more later?

Yes. The hub grows with your boat — add wired or wireless sensors any time and they pair in minutes.

What's included with the hub?

The Roam Hub, mounting hardware, and the wiring harness. You choose your plan in the Roam app once it's installed — free on your own WiFi, or cellular from $5/mo billed annually.

We'll happily spec a system with you — send us a message.
