====== OpenAiways ======

Community notes and findings for keeping the **Aiways U5** alive and connected after the
manufacturer went bankrupt and shut down its cloud servers.

The infotainment head unit is made by **Adayo / 华阳** (vendor code ''haoke''/''hk''). The goal of
this project is to **self-host** the "connected car" features the dead OEM cloud used to provide —
remote climate, telemetry, a custom cluster display, real navigation and speed-limit warnings —
with **no cloud and no OEM dependency**.

**⚠ Own vehicle only.** Writing to a vehicle CAN bus and overriding cluster displays has real
safety implications — understand each step before doing it.

===== Status at a glance =====

**Proven:** root ADB, full device backup, CAN read/write via the head unit (SoC read, A/C control),
cluster-display override + speed-limit sign, MQTT telemetry to Home Assistant, HERE navigation / EV
routing, and an offline map-matcher for speed limits.

**Still open:** the "wake the HV system while parked" CAN sequence (needed for remote
preconditioning **and** for topping up the 12 V battery), the always-on cellular Tier-1 hardware, and
on-car navigation integration. See [[roadmap]].

//The source code for the apps and tools will be published separately in a Git repository. These
pages document the **findings** — what the hardware is, how it works, and what we learned.//
