Hub for Jaecoo Lite

For the Jaecoo J5 head unit

A small app for your J5 screen.

Hub Lite is a small, separate app for the Jaecoo J5 EV head unit. It installs next to J5 Hub. It has three pages: tyres, battery and karaoke.

Three pages

Each page does one job.

  • Tyres

    Shows TPMS pressure, temperature and warning of each tyre.

    The pressure scale is not confirmed yet, so the app shows raw values. A parked car shows "—".

    Hub Lite Tyres page. Four tiles: front left, front right, rear left, rear right. Each tile shows a dash and the text Not available yet. Drive for a short time.
  • Battery

    Shows the high-voltage battery state of health (SOH), for example 98 %.

    The button "Remove car access" on this page removes the car key.

    Hub Lite Battery page. Battery health (SOH) shows 98 percent. A Remove car access button is at the bottom.
  • Karaoke

    Plays local songs from a "Karaoke" folder on a USB drive.

    Synced lyrics come from a .lrc file next to the song. If there is no .lrc file, the app uses free lyrics from LRCLIB. Two buttons move the lyrics 0.5 s sooner or later.

    The YouTube karaoke search opens the video in NewPipe. This works only when the car is parked. GPS above 8 km/h locks it.

Questions

How does Hub Lite get car data?

You approve one time on the car. Tap "Allow car data", tick "Always allow", then tap Allow. A read-only script then reads the values. To stop access, tap "Remove car access" on the Battery page. This removes the key.

Why does the app show raw tyre values?

The pressure scale is not confirmed yet. The app shows raw values until the scale is confirmed. A parked car shows "—".

Where do I put songs and .lrc files?

Make a folder named "Karaoke" on a USB drive. Put the songs in that folder. For synced lyrics, put a .lrc file next to the song. With no .lrc file, the app uses free lyrics from LRCLIB.

Can I watch the video while I drive?

No. The YouTube karaoke search opens the video in NewPipe only when the car is parked. GPS above 8 km/h locks it.
