Guition JC3636K718C - ESPHome Voice Assistant Wiki

A full-featured Home Assistant Voice Assistant on the Guition JC3636K718C - a 1.8" round 360×360 touch display with a rotary knob, speaker, microphone and an addressable LED ring, driven by ESPHome.

You keep one thin YAML locally (guition-va.yaml); it pulls the firmware core and a set of optional screens from this repo at compile time, so updates are a re-pull and you choose which screens get compiled in.

What it does

• Voice assistant - on-device wake word ("Alexa") or press-and-hold the screen (toggleable), full HA Assist pipeline, wake beep + music ducking.
• Boot splash - a short "HELLO!" greeting with a spinning ring on startup, then the clock.
• Music player - speaker media player in HA / Music Assistant: album art, title/artist, transport, progress.
• Timers - set by knob or voice; big countdown with a depleting ring, pause/stop, alarm on finish.
• Control tiles - swipe up for four configurable tiles toggling any HA entity (light/switch/...), each with its own icon and label.
• Home screen - clock, date, battery, weather + room temp/humidity, with selectable watchfaces (Classic / Neon / your own).
• Weather screen - today plus a 7-day radial dial; the knob scrolls days, with a °C/°F toggle.
• Thermostat screen - a dial for a climate.* entity; the knob sets the target, tap toggles on/off.
• LED ring - HA-controllable light and reactive (assistant / timer / alarm / volume), each toggleable.
• Three arcade games - a lane racer, a vertical shooter, and a 360-degree snake.
• Modular screens & watchfaces - player, timer, games, weather, thermostat, sensors and a commented demo are optional packages, as are extra home watchfaces; pick which compile in and their order.

Quick start

1. Copy secrets.example.yaml → secrets.yaml, fill in Wi-Fi.
2. Copy guition-va.yaml and partitions.csv together; edit substitutions: (HA URL + your entities + the four control tiles).
3. Everything else - the firmware core, the screens, fonts, images and sounds - is pulled from GitHub at compile time, so guition-va.yaml + partitions.csv + secrets.yaml are all you keep locally.
4. First flash over USB (16 MB partition table can't be set via OTA), then OTA.
5. In Home Assistant, assign an Assist pipeline to the new device.
