Quoted from scorbit:able to set happy hour pricing
I tried the other Bluetooth pay device, while neat it could be pretty glitchy. Always assumed it was the other 2.4 ghz networks in the center, there were at least 20 wifi networks on that frequency in range. I did the happy hour stuff to, took a lot of time to set up every time. Asked several times if they could group the machines (via software), but never received resolution.
