Hello @dfarache-ebike, Thank you for your quick response. I want to save and store some data points to file or database. With these stored data, I would like to study the route I have taken and how I can optimize my use of energy according to the level of assistance and the route I have taken. The idea is just to have a record of my day's route with the different parameters stored. King regards, Can ESER.

Hello! I want to save and store some data points to file or database. Accessing these values and displaying them on the screen of my smartphone was not complicated. But I have some problems to write them to a file or store them in a database. I used "local storage" and the code that you have given in a previous topic but it doesn't work. I'm not a Java or HTML developer, I just have some basic knowledge. So I really need your help actually. My first option was to use Firebase to host my Web application (module) and to have a database. I have tested the connection of my web application with the database and it works without any problems. For example, with "surname" and "first name" blocks to be filled in, I can store the different surnames and first names written in the web app. But I don't know who to store the battery level, the speed, user Power... I am using the "SaveDataToLocalStorage" function which that looks a lot like your code. In this function, I am storing strings in local storage and then I try to get the value by using "getElementById" and push the value to firebase. This function is launched as soon as I press my submit button (as you can see at the end of the code). But I don't get anything on firebase and I don't know why. <!DOCTYPE html>

<h1>User Database</h1>
<button onclick = "SaveDataToLocalStorage()">Submit</button>
</body>
</html> Another option was to simply save the data to local storage and then displaying it when off-ride without storing them in database. This option should be easier as you said in a previous topic. But in this case, if I am just using your code: function SaveDataToLocalStorage(currentSpeed, currentUserPower)
{
var speedValues = [];
var userPowerValues = []:
// Parse the serialized data back into an aray of objects
speedValues = JSON.parse(localStorage.getItem('speedData')) || [];
userPowerValues = JSON.parse(localStorage.getItem('userPowerData')) || [];
// Push the new data (whether it be an object or anything else) onto the array
speedValues.push(currentSpeed);
userPowerData.push(currentUserPower);
// Re-serialize the array back into a string and store it in localStorage
localStorage.setItem('speedData', JSON.stringify(speedValues));
localStorage.setItem('userPowerData', JSON.stringify(userPowerValues));
} With your code, I will be able to store data in localStorage but how can I get these values then? Should I have to create another web app? Or should I have to create a Python script to have access to data stored in localStorage? Thanks in advance, and hope you'll answer me because I'm really stuck... Can ESER.
