There is a new form design of the HAP ac lite
the new case is black and is not square. does not stack easly. Status lights are not easily seen.
I have programed up three today and they are working flawless.
Theme by Danetsoft and Danang Probo Sayekti inspired by Maksimer
I have one of the newer HAP AC Lites as well - the black one with the funky shape. I can confirm that mine loaded the latest firmware just fine.
