Just like with all other electronic products, your Calex Smart devices switch off when there is no power. As soon as the power comes back on, in some cases the lamps/appliances start working again automatically. If this happens, the settings are saved and you do not have to take any action. Unfortunately, it is also possible that the lamps immediately start blinking or that the devices are offline. In this case, the items are reset and you need to reconnect them to the app. With the help of these step-by-step instructions you can pair your smart items again. The name you have assigned to the item will be remembered when you pair it again.
