Hold on a minute. The black controller you have should work with the 12 volt LED strip if you connect the 12 volt AC adaptor to its power input.

Yes. Find the two pins where the voltage reads +12 volts.
I'm assuming the arrow pin is negative. So connect black lead of your meter to this pin and see if there is 12 volts on one of the other 3 pins.

With black probe on arrow pin none of them. It showed 12v when I put black probe on power supply jack and red on arrow pin.

Appears the WIFI may be switching the low side. Then connect the positive side of the LED strip to the arrow pin and negative to one of the other pins

Tying the three outputs together as you have shown, is a bad idea. You might create a short and damage the wifi controller.

Why not tie the B (blue) connection to the led strip, leaving the R and G disconnected? Then you just control the strip with the B channel, ignoring the other two. Blue and white LEDs use a similar amount of color (closer than red or green LEDs)

It looks like the Wi-Fi controller is for an RGB strip. It has three channels; one for each color. Just use one.
Ok but does the dimmer function works with this way
