Fleet CAN Bus Monitoring

Secure remote access to distributed vehicles or machines via VPN

When CAN-equipped vehicles or machines are spread across sites, faults go unnoticed until something breaks. Helix provides secure remote access to each device via Tailscale VPN, letting you connect directly to any asset from anywhere — no exposed ports, no complex networking.

How It Works

Step-by-step workflow for fleet can bus monitoring.

1

Install Helix per asset

Connect a Helix device to the CAN bus of each vehicle or machine you want to monitor.

2

Join your Tailscale network

Register each Helix device on your Tailscale network for secure, encrypted remote access.

3

Access devices remotely

Connect to any Helix device from anywhere on your Tailscale network to view decoded CAN data and monitor asset health.

Challenges & How Helix Helps

Every challenge has a built-in answer. See how Helix addresses common problems engineers face.

1
Challenge

No remote visibility

CAN data stays local to each vehicle or machine. Faults are only discovered when an operator reports a problem or the asset comes in for scheduled maintenance.

1
How Helix Helps

Tailscale VPN access

Each Helix device joins your Tailscale network, giving you secure, encrypted remote access to any asset without exposed ports or firewall changes.

2
Challenge

Heterogeneous bus layouts

Each asset may carry signals from multiple subsystems — power distribution, climate control, hydraulics — with a mix of message formats that generic CAN tools cannot decode.

2
How Helix Helps

Direct device connectivity

Connect directly to any Helix device from anywhere on your Tailscale network. Access decoded CAN data, update configurations, and monitor status in real time.

3
Challenge

Scaling across a fleet

Monitoring a single asset is straightforward. Rolling the same setup across dozens of assets — each accessible remotely — requires secure, reliable connectivity without complex network configuration.

How Helix Helps

Zero-config networking

Tailscale handles NAT traversal, key management, and encrypted tunnels automatically. Deploy new assets without reconfiguring your network infrastructure.
