  1. Michael

    The Shelly 1 is even smaller than I expected. Looking forward to getting it installed. Thanks for the fast shipping

    Used one to build an remotely activated garage opener. Just followed some youtube videos and quite easily wired to my garage opener unit. Recommend this to anyone looking for an easy DIY project.
