Very much a work in progress atm, just putting it in gh so I don't loose my WIP

Some screenshots using generated test data:

Averaged view:

All entries view:

requires libomron to be installed. (will be migrated to using a libusb go wrapper instead)

Create udev rule in /etc/udev/rules.d/51-omron.rules with content:

SUBSYSTEM=="usb", ATTR{idVendor}=="0590", MODE="0664", GROUP="plugdev"

If it's not working right away, force udev to be reloaded:

sudo udevadm control --reload
sudo udevadm trigger

You also need to be in the plugdev group .
