Hi

I'm getting the following error output when starting the script:

pi@emonpi:~/dev/evoGateway $ python3 evogateway.py
Traceback (most recent call last):

                  ^
SyntaxError: invalid syntax

Any suggestions on what might be going wrong?

Thanks

ah, it looks like I need Python 3.8+ for the walrus operator (https://docs.python.org/3/whatsnew/3.8.html) and raspbian is currently shipping with 3.7... I'm updating now and will close once it's working

working now... :)

Glad you figured it out! :)

So what exactly did you do to solve it? I had the same issue on my Rpi and used a link to upgrade python 2.7.x to 3.9.7 which worked but now the script still isn't working

Running Python -V gives me 3.9.7 and running python3 -V gives me 3.7.3.

Didnt had too much time yesterday trying to figure out a solution so I'm curious to what you did to get it too work.

I had a few things to sort out, didn't keep any notes but happy to provide more details if needed, outline steps were:

Other than the above, it's probably worth checking your device is sending data over serial port (minicom -D /dev/ttyACM0 in my case) and maybe worth trying the ramses_rf cli to make sure the problem isn't lower down the stack?
