Troubleshooting

Unable to run the tool pykmp-tool: command not found

Using a Python package manager (e.g. pip) should ensure the entry point should be installed somewhere in a directory that's on your PATH, but apparently that failed.

As an alternative, you can try to substitute pykmp-tool with python -m pykmp.tool.

Unable to get a reading (connection timeout)

• Make sure your IR head has an included magnet that activates the meter's IR circuit. If in doubt, activate it by pressing any button and try to get a reading while the display is active.
• Make sure the RX/TX is aligned with the meter. It's most if not all cases the IR head has to be placed in upside-down position.
• Try to re-align around the position of the IR optical head while keeping a command running in a loop in your shell.
