Build Your Smart Home! Your relatives are already of an advanced age and the danger of injuring themselves in the household and finding it difficult to get help is particularly great? Then the SOS button is a good alternative. You can simply attach the button to wheelchairs or your wrist with a cord. If it is pressed, you could be notified via the Smart Life App or you can have the alarm SH0110 triggered, for example, then you will also receive an acoustic alarm in your home and you can react quickly.
