Sentinel

Battery and equipment monitoring you do not have to think about

Sentinel is ReCore's first product line. It watches battery voltage and temperature so equipment does not get discovered dead, and it is currently in prototype and field-testing.

What It Monitors Today

Voltage and temperature, measured where the battery lives

Working now

The current Power Node prototype measures battery voltage and temperature, the two most direct indicators of whether a battery is healthy or heading for trouble. It samples continuously and reports every 15 minutes in the field, or as often as you configure it.

Power Node

A small battery-powered sensor that attaches to the battery or equipment being watched. It reads voltage and temperature and transmits over LoRa, a long-range, low-power wireless protocol, so it works across pastures, equipment yards, and shops without Wi-Fi.

Sentinel Hub

Receives readings from one or more Power Nodes over LoRa. It runs a local dashboard on your own network and, when it has an internet connection, forwards the same readings to the ReCore cloud on your schedule.

Local Dashboard

A dashboard served directly from the Hub, viewable from a browser on your local network. It works whether or not the Hub has internet access.

ReCore Cloud

The Hub uploads telemetry through an HTTPS Cloud Function into Firestore. This path is working today; historical charts and alerting built on top of that data are planned.

Local-First, By Design

The dashboard does not disappear when the internet does

The Sentinel Hub is built so that losing Wi-Fi or internet access does not mean losing visibility into your equipment. Sensor readings keep flowing over LoRa, and the local dashboard stays live on your network. When internet returns, the Hub catches the cloud up with buffered readings.

Remote Control Center

Monitor your Sentinel network from anywhere

A cloud dashboard is now in development that displays live telemetry from your field-test sites, historical charts, and remote control capabilities. Try the prototype demo below.

Example Use Cases

Built for equipment that sits still, sometimes for too long

Stored vehicles
Tractors & ag equipment
Equipment yards
RVs
Boats
Fleet support vehicles
Backup & standby batteries

Current Status

Where the prototype stands today

Field-testing

Sentinel is currently a working prototype being tested on real equipment in real conditions. The full path from Power Node to LoRa to Hub to local dashboard to Firestore has been proven. Cloud-side features like historical charts, alerts, and account login are in active development.

Planned Capabilities

What is planned next (not yet available)

Planned

Historical charts & trends

Graphing past voltage and temperature readings over time in the cloud dashboard.

Planned

Alerts & notifications

Configurable warnings when a reading falls outside a safe range.

Planned

Account login & device management

Secure multi-user access and a proper interface for adding or configuring nodes.

Planned

Cellular connectivity

Primarily being considered for the Sentinel Hub, with direct-cellular nodes possible for isolated locations.

Planned

Production hardware

Ruggedized enclosures and manufactured boards beyond the current prototype build.

Have equipment that could use a Sentinel node?

We are looking for real-world conditions to field-test against. If your stored vehicle, tractor, RV, boat, or backup battery sounds like a good fit, let us know.
