Wireless CAN Bus Decoder - Sync Your CAN Data to the Cloud

CAN Bus WiFi Cloud Data J939 OBD2

For the best intro to this WiFi CAN logger, check out our 7 min video above!

Retrieving CAN bus data can be a hassle.

Difficult to reach places. Remote locations. A fleet of two hundred trucks.

Wouldn’t it be fantastic to easily retrieve your logged CAN data wirelessly via WiFi?

Now you can! The new CL3000 wireless CAN bus decoder lets you easily pull or push CAN data via WiFi - without ever disconnecting your logger.

This is not just an upgrade: It’s an entirely new product

With WiFi, you'll access a buffet of convenience, cool new features & new use cases!

  • Want to fetch CAN bus data remotely across the globe? No problem
  • Auto sync J1939 data from 50 trucks to an FTP server? Easy
  • Or just enjoy a vastly more convenient CAN logger? This is for you

The CL3000 is plug-and-play, supports high-speed ISO-11898-2 CAN (e.g. J1939, OBD2, CANopen) and it's efficiently powered via the CAN bus. Further, it connects via router, PC, smartphone across multiple modes.

And the best part?

It costs only 399 EUR. With free software, support, 2-year warranty & international shipping!

So what makes the CL3000 special?

It’s wireless.

No hocus pocus: Our newest CAN bus logger "simply" works like a WiFi-enabled CL2000.

Revolutionary innovation? No. 

But it’s a game changer in convenience and core features that our early users now find hard to live without! 

To explain how the CL3000 works, let’s start with the two WiFi modes: Access Point (AP) and Station (STA).

Cloud Wireless CAN Bus OBD2 J1939 Logger Access Point Mode

1# ACCESS POINT MODE: The CAN logger ships in AP mode, meaning that it will simply show up as a “hotspot” on your PC, phone or tablet. 

Just log on and access your data by entering a pre-specified link in your browser (e.g. “ID0001/”).

Example: You’re in the field with your iPad and wish to collect CAN bus data from a hard-to-reach logger. You get in range, log on to the hotspot and download the log files you need - while the CAN logger continues logging!

WiFi Vehicle Fleet J1939 Logger Station Mode

2# STATION MODE: The IoT CAN logger can easily be configured to auto-connect to an existing WiFi hotspot. Once connected, your CAN bus data is accessible via any device on the network via your link & password. Note that a hotspot could be e.g. your local network router, a PC/phone/tablet built-in hotspot or mobile hotspots in trucks.

Pro Tip: If you want to access the logger outside your local network, this can be done if you are on the same VPN as the hotspot. Alternatively, you can easily set up port forwarding to turn your access link into an online website for easy global access - check out our quick guide here.

Example: You need to monitor CAN based equipment at a client site. By connecting your CL3000 to their router with port forwarding, you can access log files anytime, anywhere - without bothering your client.

To illustrate how the STA mode and port forwarding works, check out our live CL3000 web interface below!
Feel free to download a file and play around with it in CANvas to test the functionality.

TIP: If you want to download all files in STA mode at a time (as a batch), you can e.g. use a batch Chrome plugin.

Link not loaded correctly

The above are useful to "pull" ad hoc specific CAN bus data files on a need basis.

But what if you want to get all data from e.g. 50 trucks daily?

This is where our “push” functionality comes in:

Push / Auto-Sync CAN Bus, J1939, OBD2 Data to FTP / Cloud Server

FTP PUSH: In both AP and STA mode, the WiFi CAN logger can be set up to automatically push new log files to a FTP server. Once a log file has been uploaded, it is deleted from the SD card to free up space and avoid duplicate transfers.

Example: You need to collect J1939 data across 50 trucks on a daily basis. With the PUSH mode, the J1939 log files in a truck can be uploaded on-the-go via e.g. a mobile WiFi 4G celluar hotspot in the truck to a cloud server. Or, the data can be uploaded when the trucks return to the garage and loggers come within range of the local WiFi router. In both cases, the data can be auto pushed to a single FTP server folder for easy processing at scale. For true automation, you can combine this FTP push feature with our new scheduled auto conversion in CANvas. This lets you easily auto convert your CAN bus data in the Cloud.

Check out our new FTP Push deep-dive! This feature is perfect for use in e.g. fleets of trucks, tractors, forklifts or bobcats as it does not require manual interaction and hence scales easily. Further, the WiFi logger can be configured in minutes to connect to e.g. a client WiFi network, a mobile phone hotspot or a 4G MiFi - and to your preferred FTP server. It is super simple!

Still unsure whether to get a CL3000? Then check out our top 5 reasons why this is the best WiFi CAN analyzer!



Do you want more time for the fun stuff? With the CL3000 you avoid the hassle of disconnecting your CAN logger to retrieve data. Completely. Is your logger in a difficult-to-reach location? Don’t fret! Just connect wirelessly and download the CAN bus data files via your PC, phone or tablet. Want to access the CAN data from a remote location? Different country? Just auto push the CAN bus data via WiFi to your Cloud server.

Perfect for e.g. monitoring or troubleshooting your CAN bus equipment at a client site - half-way around the planet!



With the CL3000 you get WiFi transfer speeds of up to 9 MB/s - up to 20x faster than the USB transfer of our 1000/2000 models. This lets you transfer 1 GB in ~5 minutes - or less time than it takes you to grab a cup of coffee!



Want to get data from across 50 trucks in a garage? Taking out CAN loggers 1-by-1 to transfer the data is simply not feasible. However, with WiFi you can auto-sync data to folders on a server when in range of a specific WiFi hotspot. Further, you can use our free CANvas software to load, DBC-convert and merge the files. All in a few clicks!

Further, the SD card gives you a 16 GB "buffer" for your CAN data. If the CAN logger goes out-of-range, you won't loose data. Rather, the CAN bus log files will simply be uploaded once the WiFi hotspot comes in range again.



The CL3000 comes in the usual small, robust enclosure without external antennas. Despite this, it boasts impressive WiFi specs: 16 GB SD card storage, wireless transfer speeds up to 70 Mbps (~9 MB/s), support for 802.11 b/g/n and security via WEP, WPA, WPA2 with password protection. Power consumption is only 1 watt when logging so you can leave it in your vehicle for months without draining the battery.



The price of a CL3000 is only 399 EUR - including free software, support, 2-year warranty and global shipping! It’s more than the CL1000/2000, yet still one of the cheapest CAN loggers on the market (incl. non-WiFi loggers!). Further, our users find that the time saved using the 3000 pays back the added cost almost instantly.



We hope you’re as excited as we are for the CL3000!
