AutoPi Cloud
Everything needed to operate and analyze connected fleets.
AutoPi Cloud combines device management, fleet management and data logging into a single platform. It offers detailed insight into vehicle status, CAN bus activity and installed edge applications. Use the fleet management layer to keep track of vehicle position, usage and health, and the device layer to configure logging profiles, triggers and alert handling.
Edge devices can record large amounts of CAN, CAN-FD and OBD-II data and upload it to cloud storage or external analytics pipelines. Configuration and updates are handled centrally, making it practical to operate many vehicles across different regions.
AutoPi Cloud access is included with all AutoPi devices.
-
Advanced CAN logging.
- Configure logging for dual CAN-FD streams and upload data continuously to remote storage or on-premise systems. Use the edge device for on-device decoding with DBC files and export in JSON, MDF4 or CSV formats. Mixed 11-bit and 29-bit identifiers are supported on the same installation.
-
Remote edge computing.
- Deploy and monitor containerized applications directly on the devices using Docker and Tailscale. Scale processing from simple filtering to local model inference, without changing the hardware platform. Custom applications can be versioned and rolled out per project, per fleet or per vehicle.
-
Device management.
- Manage configuration and behavior for all devices from a central interface. Define rules per vehicle, group or project, including which signals are logged, when data is uploaded and how alerts are generated. This gives consistent behavior across different installations and vehicle types.
-
Over-the-air updates.
- Update firmware, base images and applications remotely without physical access to the vehicle. AutoPi Cloud handles roll-out plans, progress tracking and potential rollbacks, which is important when devices are deployed across different sites and time zones.
-
Powerful API.
- Integrate AutoPi devices and cloud services through HTTP REST and MQTT endpoints. Access data such as location, speed, engine parameters, EV battery state-of-charge and custom application metrics, and route it into existing backends or data platforms.
-
Fleet management.
- Monitor location, usage and status for entire fleets from a single dashboard. The fleet view supports drill-down on individual vehicles and can be combined with alerts, maintenance intervals and usage-based reporting, making it easier to operate mixed fleets across sites.
Extendable
Extend the AutoPi devices to any vehicle or machinery
Extension and adapter cables make it possible to install AutoPi devices in a wide range of vehicle architectures. Heavy-duty adapters cover common J1939 connectors used in trucks, construction equipment and industrial machinery, while the standard adapter range includes OBD-II extensions, power cables, splitters and OEM-specific adapters.
This approach keeps installation flexible, preserves access to diagnostic ports and supports both light-duty and heavy-duty networks without redesigning the hardware.

The AutoPi device range covers different usage patterns. AutoPi CAN-FD Pro is built for dual CAN-FD logging and high-throughput data collection, with export to external clouds or local storage. TMU CM4 focuses on edge computing, where Docker-based applications process data near the vehicle before forwarding selected information. AutoPi Mini specializes in EVs and provides extended parameter sets from OEM-specific PIDs, including battery health and range-related metrics.
All devices integrate with AutoPi Cloud for configuration and monitoring, and can be deployed in mixed fleets where each vehicle type uses the device that fits its requirements.

-
Plug-and-play.
- Ready for installation in 12 V and 24 V systems without prior programming. CAN-FD Pro and TMU CM4 can be mounted in heavy-duty machinery or passenger vehicles, while AutoPi Mini connects directly to OBD-II ports, which is typical in EV passenger cars.
-
Powered by Raspberry Pi.
- Open-source stack built on standard Linux (Raspbian), SocketCAN, Python and SaltStack. CAN-FD Pro and TMU CM4 use Raspberry Pi Compute Module 4, providing an industry-recognized platform. AutoPi Mini uses an embedded architecture optimized for compact designs.
-
Global coverage.
- Integrated 4G/LTE CAT1/4 modem (3G/EDGE fallback) with worldwide support in a single hardware variant. When combined with the AutoPi connectivity solution, coverage is available in more than 180 countries for cross-border projects.
-
Full CAN bus support.
- CAN-FD Pro records dual high-speed classic CAN or CAN-FD and supports J1939 and OBD-II traffic. TMU CM4 offers full CAN bus support for custom applications. AutoPi Mini operates on OBD-II queries with focus on EV parameters, which fits passenger vehicle deployments.
-
Designed for interoperability.
- Hardware and cabling are designed to be extended and adapted. External antennas, HAT solutions, storage upgrades and IP67 enclosures can be added to match project or OEM requirements, instead of starting from a custom design for each use case.
-
Made in Denmark.
- Designed and engineered in Denmark and produced in the European Union using components from EU and US suppliers. Devices are certified for global usage (CE, FCC, RoHS), which simplifies deployment across international fleets and pilot projects.

Frequently asked questions
You should choose the automotive data logger that best fits your project and your requirements. If still in doubt, contact us — we will help you setup with the most suitable solution.
Our general recommendation is as follows:
-
AutoPi Mini: You are searching for a plug & play data logger, that logs OEM and standard (EV & ICE) data parameters.
-
AutoPi TMU CM4: You want more detailed CAN data from vehicles / machines and custom configurations options.
-
AutoPi CAN-FD Pro: You require a full CAN dump of dual CAN/CAN-FD buses, with the option of additional 2 external flash drives.
Overall, the Autoi CAN-FD Pro is far superior for CAN bus data logging that supports mixed 11 bit and 29 bit frame IDs, onboard CAN decoding, remote live debugging and interaction through secure VPN, hardware encryption, etc. — then we strongly recommend this, unless you specifically require something else.
The automotive data loggers are designed to be user-friendly, letting you capture CAN bus & OBD data from a vehicle or machine's Controller Area Network (CAN) and/or On-board Diagnostics II (OBD-II) system.
-
The automotive data logger connects to the vehicle / machine's OBD-II port.
-
Once powered on, the data logger listen to the data stream and start logging raw data — depending on your project, it can either:
-
Store raw CAN data on an SD card
(This allows for local data storage, useful for projects where data analysis will be performmed on-site or later on an external computer).
-
Upload raw and/or decoded CAN bus/OBD data
(Data can be uploaded to our cloud backend, your own server, or a SaaS solution, useful for remote access and real-time insights).
-
Onboard CAN decoding
(Using DBC files, Python scrips, etc., the data logger can decode CAN signals directly on the device. This feature is ideal for projects that require immediate, on-device analysis or for devices without a constant connection to an external server. Only available on the AutoPi CAN-FD Pro).
-
-
From here, you can access the log files remotely or locally and begin analyzing detailed insights about vehicle or machinery performance, diagnostics, and more.
For more details, see our getting started guides which will guide you through each step and set up your automotive data logger.
To get the most out of your AutoPi automotive data loggers, we strongly recommend using the AutoPi Cloud platform — a combination of device- and fleet management.
With our device and vehicle management platform, you will get insights to all the detail you need to manage your business.
-
Use our fleet management cloud to keep track on your vehicles and the performance of these.
-
Use our device management platform to deploy advanced software configurations to the edge devices or to record large amounts of data from the vehicle CAN bus.
