All Shelly WiFi devices have a built-in web server, which means you get a wealth of features that always work. The built-in web server means that Shelly has built-in memory and will therefore remember sunrise, sunset, schedules, etc., even when the network goes down. Relays and dimmers work like normal pressure relays and can therefore be used with your normal switches - even without internet. All inputs and outputs are fully programmable and only require local WiFi to communicate between devices. However, we still recommend having an active internet connection, as it opens up even more features.
