What is miyoo-mini-card?

miyoo-mini-card is a custom dashboard card for Home Assistant (a popular open-source home automation platform) that displays live status information from a Miyoo Mini Plus handheld gaming device. If you have a Miyoo Mini Plus running OnionOS and you also run Home Assistant at home, this card lets you monitor your gaming device from your smart home dashboard. The card shows a photo of the device with the currently running game overlaid on the screen, a status line, and a four-cell stat grid displaying things like battery level, volume, temperature, and playtime for the day. A bottom action bar shows live indicators for WiFi connection, NTP (network time sync), and mute status. To use this card, you first need to set up the companion project miyoo-mqtt-reporter on your Miyoo device. That daemon publishes the device's live state data to an MQTT broker (MQTT is a lightweight messaging protocol common in home automation). Home Assistant reads from that same MQTT broker and automatically creates 73 sensor entities for the device, which the card then pulls together into a single visual display. Installation is done through HACS (Home Assistant Community Store), which is the standard way to add community-made cards and integrations to Home Assistant. A manual installation option is also documented. Once added, the card is configured in YAML with just the device's entity prefix and an optional list of up to four stats to show in the grid. The project is written in TypeScript and licensed under MIT.
