# Pi Status Bridge Noctalia plugin This Noctalia v4 plugin is an aggregate-status **launcher**. It renders the workspace counts supplied through its `plugin:pi-status-bridge` IPC handler. Clicking its bar widget starts `pi-status-bridge.service` and toggles the standalone Pi Status UI. Set `PI_STATUS_UI_BINARY` to override the UI binary; the packaged local build path is the fallback. Use `pi-status-bridge-client` to query the owner-only Unix bridge socket. A local integration script should translate responses and events into the plugin IPC handler's `setBridgeState(state, projectLabel, attentionCount, detail)` call. The plugin never opens a Noctalia panel, sends prompts, switches sessions, chooses a worktree silently, or approves extension requests. Install/register it through Noctalia's normal plugin workflow, then add its bar widget in Noctalia settings.
