• You can start by looking at the various devices in the Shelly store and reading the product descriptions tom familiarize yourself with the hardware.

    Once you have done that, look at some of the threads here and YouTube videos on implementation to get an idea of what your goals are.

    When asking for help in designing or implementing something it is a good idea to state what country you are in. Also, you mentioned renewal, does that include a complete rewire?

    Depending on your requirements, some of the new Shelly features permit you to be independent of the cloud, and even local wifi.

    Good luck with your project.
