I bought a trasformer with 16 V ac for the booster power8 and 12 V ac for house lights and other ... And i pleced it in the old Housing phone battery so it can't make RF disturb
This system work very well, i use it with abuot 4 train (lgb Shoema, stainz, RhB cocco, mallet 2085...) with sound smoke and so on and i haven't any problems!
I try the apple app and the android one ... The apple one permit to test the function while you are building the machine configuration ... The android one don't permit it so you have to remeber witch number of function is the smoke, wich one sound ecc ecc
I spent:
120€ for z21
149€ for booster
35€ for toroidal transformer tailored
Total 304€
A massoth set is about around 900/1000€ ... So it's great
