I understand that, always have "projects" thrown at you when you don't really need it to happen! Good luck and hopefully no major damage.I wasn't able to get the lights to respond using the dosing controller. I checked it using reef-pi software like I did with the lighting controller, assigning it to the correct pins and playing with the software to change the speed and got nothing, I didn't check to see if the pwm was responding like it did on the lighting controller with a multi meter. I would assume that it does but if the frequency is the problem I would expect the same result.
I still need to experiment with changing the pwm frequency in reef-pi.
I have to take a break from all things reef pi. I had a pipe burst in the wall behind my shower. So I'm in the process of ripping out a wall and doing some home repairs. Once that's taken care of I will get back to this.
Gotta love the messes life throws at you.:mad:
