We thought about this application in order to create a greater and more functional communication between us and our mailbox: the new means chat with the old and beloved paper.
The version with SMS is definitely practical since we all always have the mobile phone in our hands, and certainly convenient and ideal for those who spend a lot of time away from home because of their job or those who own a second home. How does it work? Simple! You will be notified with a text message on your smartphone every time you receive mail. What do you have to do? You need to connect this support by calling your trusted electrician, using for example the power supply of your doorbell, and getting a simcard.
We are also developing a system to use Wi-Fi connection. It is still in the design phase but we plan to put it on the market in 2019.
