Start with Reef-pi

[mapama]

Hello,
Sorry for my English.
I am redoing my Amazonian aquarium of 1000 liters. And I intend to use reef-pi.

I started assembling everything and I have two questions:

1- I control my leds with a PCA9685. I hooked it up to a 48v power supply. I can't dim the lights. They are always 100%

2- For MQTT, my reef-pi is at IP 192.168.1.29, and my mqtt server is at 192.168.1.7. Is the configuration page correct like this?

If you have any idea to help me...

between PWM and GND i have only 1v max. what could i have missed ?

 

[theatrus]

If the PWM is working and you set it to about 1/3rd, you'd see 1V on a 3.3V system when using an averge volt meter

 

[mapama]

does the frequency matter?
The measurement must be taken between gnd and pwm? between black and yellow?
thanks for the help

it was my pca9685 not working. it seems to work fine now with the new one.

another question :
Is it possible to enable and disable a light (manual:0 or auto) via API or MQTT ?

Via api yes, not via mqtt
