I also had problems with lock files not being accessible. After deleting them (several times) it works for now. Need to find a solution for this problem. Has been working the whole day now. You can check if you have this problem bij maken your script file executable and running it from the terminal. You will immediately see if the script runs OK or if the LCK file are blocked.

Also see if you got the right USB defined. I've noticed the USB port number can change just from restarting... Really annoying since the script will not work. There is a solution for this but this is not so simple.

My code for reading and sending the total of the meter and instant power:

The code for a meter with the imported and a meter for exported kWh's. I tried doing all the meters in one file, but this did not work for some reason. Put the code in a .sh file and run it every 5 mins with a cron task.
