This is a smart switch module from Shelly, designed for users who want to keep their existing switches while bringing remote control, timers or voice commands to their home. It is especially useful in older apartments and houses where a neutral conductor is often not available.

Evaluation of key product features

Installation does not require any special knowledge - simply install the module in a box behind the switch, and you can immediately monitor or control devices remotely via the app. A special feature of the 1L model is the possibility of installation without the presence of a neutral conductor, which makes it accessible for most existing electrical installations in Slovenian homes.

Connectivity is based on Bluetooth communication, allowing you to quickly establish a connection with your device and instantly control your lights or devices. Bluetooth ensures solid connection stability indoors, and also makes it easy to integrate into smart systems without an additional hub or complicated settings.

Because Shelly 1L preserves and upgrades your existing classic switches, it adapts to your living style and does not require visible changes to the space. With compatibility with numerous smart platforms and the ability to control via a mobile app, you get above-average flexibility - turn devices on and off anytime, anywhere.

Same summary

Shelly 1L (cyan) is a built-in smart switch module that is especially suitable for those who want to upgrade existing switches in an apartment or house without major interventions in the installation. Due to its support for the Bluetooth protocol, it can enable quick connection and simple control of devices via an application or physical buttons. The module makes the most sense where the user is looking for a convenient solution for automation of lighting or basic devices, but is not necessarily suitable for very demanding automation in large smart systems with many devices and advanced scenarios. When installing, we recommend checking the space in the box and the existing installation.
