Updated 2023-05-04 ! This post focus on  Shelly 1 (S1), a really a nice automation device with great versatility, but much of the content is also valid for some of  Shellys other devices  using the gen1 API. Setup for the later version,  Shelly Plus 1 , is found here  !! S1 is a WiFi switch, 16 Amps, with dry contacts and t he function "without Internet" + that the S1 can use a 12V DC source makes it perfect for an "use case" in a  boat /mobile home. It's compatible with Alexa , Google  or HomeKit using HomeBridge  or as a "native" HomeKit device using  Mongoose firmware (Flashed via a standard WEB browser !)

Updated 2023-05-03 ! In a  former post I made a writing about Shelly 1 (S1) and this post will handle about the successor Shelly PLUS 1 (SP1)  but much of the content is also valid for some of  Shellys other devices  which uses the same software/API. To keep it simple, SP1 is a WiFi switch, 16 Amps, with dry contacts but compared to the S1 the hardware and the software is updated.  The function "without Internet" + that the SP1 can use a 12V DC source makes it perfect for an "use case" i n a boat/mobile home .

Updated 2023-05-01 ! I really recommend flashing, via WEB-browser, the device with Mongoose software to avoid Homebridge.   HomeBridge is used for this setup and to make it appear in the Apple Home app. The main advantage with the Shelly devices are that they are WiFi enabled and therefore You don't have to use a hub, this compared to z-way/zigbee and some other solutions.  First install Shelly1 (S1).
