DOA KC868-A16

you need confirm whether your tasmota firmware have enabled PCF8574 function.

I did all this https://www.kincony.com/forum/showthread.php?tid=5432 but PCF8574 does not show up?
Update: it seems there is a crucial part that is missing from that guide, i had to go "configure other" and set {"NAME":"KC868-A16 rev 1.4","GPIO":[32,1,1,1,640,608,1,1,1,1,1,1,1,1,5600,1,0,1,1,5568,0,1,1,1,0,0,0,0,1,1,1,1,1,0,0,1],"FLAG":0,"BASE":1} and [ x ] Activate and save

One last question when i turn on and outputs i cant measure any output with multimeter im using this: 
 
im measuring between output 1 and the 12/24V


Do i need to connect the 12/24V to my power supply or is it internally connected on the PCB? As the next diagram suggests i need to connect it to a power supply?


This is my real world test:

I dont see the output lights, light up on the PCB or the Relay switching. 

My Tasmota settings:
