about driver for Xiaomi yeelight - I think my colleague has one in his house, we'll make PHI module in a 3-4 weeks, together with the new release. Not sure is it YLDP02YL but I'll check.
about setup error code 23 - it happens when controller is unable to write data (API keys) on disk. what hardware you are installing EVA to? is its hard drive working w/o an errors?
