As of now we don’t have support for any gpio expander . There were plans for supporting mcp23017, but it’s not done yet. Any chance you can use WiFi based outlets ?I am currently working on a new Reef-pi build for my 220. Has anyone ever maxed out the GPIO on their pi? I am intending on using all of the GPIO and was hoping someone has successfully used a GPIO expansion board for more IO. Do any of you have experience with this?
Thanks in advance.
