Hardware · Combo Tracker

A tracker. A gateway. A store-aware locator.

Cellular, GPS, and Wi-Fi for tracking its own location. Bluetooth 5.2 scanning that picks up peel and stick beacons, sensors, and your store's existing Electronic Shelf Labels — turning installed ESL infrastructure into a precision indoor positioning grid tied to your planogram.

Why Combo

One device. Three jobs.

📍

Tracks itself anywhere

Cellular + GPS + Wi-Fi for precise outdoor and indoor positioning. Same coverage profile as the DTx HD, with up to 7 years of battery life on 3 x AA.

📡

Scans nearby tagged assets

Built-in Bluetooth 5.2 gateway picks up peel and stick beacons and sensors — a mobile gateway for hand baskets, totes, stocking carts, and other tagged-asset fleets.

🏪

Reads the store's ESL grid

Detects Electronic Shelf Labels and other 3rd-party BLE infrastructure already deployed in the store — turning what you've already paid for into meter-level indoor positioning.

The hidden advantage

If your store has ESLs, your store already has indoor positioning.

Most modern grocery and big-box stores have already deployed Electronic Shelf Labels — small e-paper price tags at every facing. They broadcast Bluetooth, and each label is tied to a SKU and a planogram position. The Combo Tracker scans those labels as it moves through the store. The result: meter-level cart location, store-floor heat maps, and dwell analytics — using BLE infrastructure you've already paid for, without installing a single beacon, gateway, or Wi-Fi access point for tracking.

Used for

Track your carts through existing infrastructure.

The Combo Tracker can act like a gateway on a cart, reading any BLE broadcasting asset in the store. If your ESLs have fixed UUIDs and a broadcase signal, you have a ready-made tracking grid for your carts by using the Combo Tracker.
