@sstallion Hi! Yes, the PowerBlock does some software debouncing. Please contact me at contact (at) petrockblock.com and I can send you a firmer with the momentary button support disabled. I have this, in fact, already prepared.
@cjdawson Please post your Kodi log (http://kodi.wiki/view/Log_file) and also describe everything that you have connected to the Raspberry Pi.
