Project Title: Instant Notification Tool [WebApp] for indicating low fuel levels
Introduction: A vast majority of cars owners/drivers don’t keep extra petrol/diesel for emergency use when the cars run out of fuel. They have to keep an eye on the fuel meter(which in case of some old models doesn’t provide a proper indication as well) and then refuel the car at the nearby fuel station. Our tool makes the job of the user much simpler and fluid.
- Web Browser
- Internet Connection
Flow [how it works]:
- User opens a web browser on his mobile device.
- User visits our WebApp URL.
- User clicks on ‘Allow’ Push Notifications.
- User views the current fuel level. (in % )
- As soon as the level reaches (25%) the touchpoint, the user receives a push notification via the web browser. All the stuff is locally hosted.
Utility: We send push notifications to the user’s mobile device as soon as the fuel levels are below a certain limit(which can be decided by the user) and are default set to 25%. Users can also view their fuel levels by clicking on the ‘Show Fuel Level’ button on our WebApp. Also, users’ can view all nearby fuel stations by clicking on ‘Click to Find Gas Stations near You’.
Why we couldn’t implement push notifications as of now?
Notifications service has been withdrawn from the HTTP server in all modern browsers(very recently); only servers with https certification allow notification access. Unfortunately, our ESP8266 is hosting the webpage locally and can only have a self-signed certificate which is again blocked in all modern web browsers thus having only HTTP server in hand. What we can do is have a third party notification sender like Telegram or IFTTT, in which each user has to have an account in the said services, get auth token and use it in the NodeMCU device to have the utility of Notification services.
