    Also here to balance out the negative

    Shelly products are solid and there is no need for this to have a lower star rating just because someone couldn’t use the chat function.

    Balancing an idiotic negative review

    This review is only to balance out an idiot who doesn't know how to use email or the chat function. Small businesses can't afford to have stupid people give bad star ratings only to ask a question. I look forward to using this module along with others I have already installed from Oz Smart Things!
