Why is it not possible or no longer possible to access my SMART HUB-150?

There could be several reasons for this. Here are a few tips for making a Bluetooth connection or reconnecting: 1. First check whether the SMART HUB-150 is still receiving power from the power outlet. 2. In the settings in your phone or tablet, check whether Bluetooth is switched on. 3. Reduce the distance to the installed (and previously connected) SMART HUB-150. 4. Increase the distance of the SMART HUB-150 and/or your phone/tablet to other wireless devices. A disruption may occur. 5. Ensure that the distance to microwaves, Wi-Fi routers and large metal objects/structures is as large as possible. A disruption may occur. Try the following tips: 1. Is your phone or tablet also connected to several speakers, headphones or other devices? Disconnect the devices you use infrequently or not at all. The reason is that your phone is overloaded at a certain point. 2. Try restarting your phone or tablet.
