Evaluation of key product features

The installation of the modules is completely simple and discreet, as you can hide them behind classic switches or in an electrical box. The entire control works via a smart application that never “gets stuck” and gives you the freedom to adjust schedules, time delays and remote on / off functionality. Bluetooth connection ensures fast response and security without complex configuration.

In practice, you will get a feeling of greater autonomy in your everyday life - you can turn off the lights without getting up, automate the heating or fans, and make sure that the lights automatically turn off when you don't need them. Unlike older solutions, the module does not require an additional "hub", which makes your smart upgrade cheaper and simpler.

Shelly 1 Gen3 stands out with its combination of mini dimensions and extremely wide compatibility - it works with most classic electrical wiring. It can be easily connected to other systems in your home, and Bluetooth means that future upgrades will be easy. This relay is a great choice for anyone who wants to add smart features to their home devices and stay ready for new smart home trends.
