Anyone toying with a Raspberry Pi or an Arduino for automation? I currently have an Arduino Mega doing my calcium and alkalinity dosing as well as controlling my ATO that is directly plumbed into the RO/DI. Im currently adding pH monitoring, dual temp probe monitoring, and setting it up to control my refugium lighting. It will eventually do data logging, host a local website with stats, and will email when specific activities occur like after power resumes, if pH or temp are outside normal parameters. Hoping I will be able to also program in wavemaker control. At the moment, I only have 4 AC outlets relay controlled by the Arduino but I will eventually add at least 4 more. Once I get everything inside a case looking pretty I will post pics. Just wondering if anyone else is toying with these.
