I have good news. I used a small prototype board for everything. made sure no line was more than 6 inches long. I soldered (My soldering sucks!) the capacitator right next to the radio and Bahm! Domoticz picked up all powered devices.
Lessons learnt, keep length of your wires short, nRf24 MUST have a decent capacitator to smoothen out power. Don't rely on GPIO pins to power it, use a regulator. Though help may come from all and sundry, its all up to you to check their suggestions... Thanks all for helping me.
I can finally retire my Nano-Serial Gateway! Wont be upgrading for a long time to come
