Hi ! I have succesfully got the UNI integrated with my garage door opener. I had a problem getting a low signal on the sensor input from my wiring to the garage controller - voltage fluctuated in closed position between 0.6-1.7 volt ). Solution was to use the ADC input and some coding in NodeRED - very flexible this little UNI.
I am now going to replace my old arduino home ventilation controller with 2 UNI's and have some question for wiring.
1. Are the GND_SENSOR and GND the same ?
2. I am planing to drive the 4 pcs 5 volt relays that draws 10-15 mA using the VCC_SENSOR 3.3 volt. Does anyone know how much (mA) you can draw from the VCC_SENSOR ? ( Only one relay will be active at any time ).
