You will be notified when and if one or more devices are offline in the following cases:
The wearable is not charged
The kettle has been unplugged from the smart plug, or the plug socket switched off. The kettle will need to be plugged back into the sensor, and the socket turned back on.
If you tap the event on your phone, you will be directed to the “Devices” tab in the MySense app where you will be able to see which sensors or devices are offline along with guidance on how to get them back online.
