What does Liase do?
With Liase, you can give your old smartphone a new lease on life by turning it into a stationary device that you can set up in your home.
In addition to useful information such as the time and weather, the display shows a button that can be linked to any notification rules.

How it works
 
Step 1
Set up with the assistant

Set up your old smartphone using our assistant, for example as a check-in button.

Step 2
Place the device

Put the device where you need it. The display always keeps on and it now acts as an input and output device.

Step 3
Configure notifications

Set your preferences on the web portal to specify how you would like to be notified in the future if the button is not pressed or if it is pressed.

Step 4
Share access

Invite family members or friends so they can be notified as well.

About
About
I am developing Liase as an individual with over 10 years of experience in the field of connected devices. From personal experience, I know how important straightforward solutions can be in everyday life—especially when things need to work simply and reliably.
With Liase, I want to create a low-barrier alternative that makes a real difference in just a few minutes, is easy to set up, and gives so-called electronic waste a second life.
