Companion app · your connected car
Your car, in your pocket.
Voltmoss talks straight to the j5-ev-dashboard telemetry server you host yourself — no cloud in between, no account with us. Point it at your server once and every number the dashboard knows follows you, live, in English, Bahasa Melayu, Bahasa Indonesia or 简体中文.
Home
Can I drive, how far, and what do I want to do right now? Charge gauge, real range, parked drain, and one tap for lock, unlock, A/C, find and stop charging.
Energy
A live charging curve, seven days of distance as bars or a calendar heatmap, running cost against petrol, and an AC/DC cost planner.
Trips
Plan A to B with charge stops on a real map, browse nearby chargers with live availability, and look back at what each trip actually used.
Vehicle
The full command grid, A/C temperature, tyre diagram, odometer, 12V health, pack health, service countdown and specs.
Home-screen widgets
Battery, Charging and Overview widgets in three sizes each, with Refresh, Lock and Find right on the widget — on iOS and Android.
Try it without a server
Type demo as the server address and explore the whole app with sample data, entirely on your device.
