tillsc / can2mqtt Goto Github PK

I had to change two lines to get it to work again with the latest builds

• line12: config = yaml.safe_load(stream)

and add encoding to the open (otherwise you get an "I/O operation on closed file")

line 66: with open (file, 'r', encoding='utf-8') as fin:

Hi - thank you this is a great project. I was looking for something that could publish decoded CAN/CAN-FD messages to MQTT broker as my end goal is to send it out to a webpage.

But my issue is that we're using CAN-FD bus and messages v/s std CAN. The config file supports bus bitrate but not ddrate - I was planning to fork and add that unless you plan to do it. Also another good option would be to support message filters because not all messages in the DBC as well as over the bus may be of interest. Hence was also planning to implement a config param to allow the user to define filters for specific messages/mask based on what is supported by socketcan.

Thank you again for a great project!

Hi there, this script works great, thank you for creating it.

I'm encountering an issue when it runs for a while but I'm having difficulty finding the cause or coming up with a fix. The MQTT broker & CAN connections do not present issues with any of the other connections to them.

Is it straightforward to detect if the script stops working and if it does to restart it? I'm a bit new at this so don't know a sensible way to do this.

Sometimes the script stops with a traceback as shown below, and other times there is no traceback but it stops bridging the messages to MQTT.
