This page is about the Hyundai IONIQ, Unfortunately, Hyundai does not offer the BlueLink system in Europe, so there is no standard solution to remotely access the current battery level. I have dealt with this topic and would like to present you my approach here.
If you are IT affine and you are familiar with SSH, MySQL and Linux, you can copy the solution easily.
The current version graphically displays the battery charge level. In addition, the last reported values are analyzed and the following additional information is displayed
Status of the vehicle: driving | parking | charging
Charging speed: slow | medium | fast
remaining charging time: hours / minutes (value is calculated by application)
The frontend is a web application. There is no installation on the smartphone or PC required!
