If your outdoor smart home device does not have an internet connection at night, this may be because the environment has changed. Often, lowered roller blinds or other barriers can significantly weaken the Wi-Fi signal. This can cause the connection to become unstable or break completely. Therefore, check whether there are any obstacles between the router and the device at night and, if necessary, try a different location.
TIP: Set up a repeater (Wi-Fi amplifier) in your garden to boost your internet signal.
