Works great with Hemsiphere! ALA also has great support. I accidentally broke mine (I snapped the micro-usb port off on the teensy; completely my fault), and ALA repaired for only cost of part!
That said, Plum has special builds of the Phazerville suite (an actively developed fork of Hemisphere) for the 1u version, so you might try that. The dev works directly with Plum to ensure compatibility, so should work.
