# 📘 Home Assistant Dashboard Examples for Gammy Bridge This document shows how to build a Home Assistant dashboard card to control **Gammy** (Windows screen temperature/brightness) through MQTT. It includes **entities**, **button controls**, **a dropdown selector**, **Mushroom examples**, and a **chips row**. Everything is self-contained and copy-pasteable. --- ## 🖥️ Entities Card with State Shows the current state reported by the Python bridge. ```yaml type: entities title: PC Screen Status entities: - entity: sensor.gammy_mode name: Current Reported Mode icon: mdi:monitor ⸻ 🎛️ Example 1: Button Controls Three simple buttons to trigger Ember, Movie, and Auto modes. type: entities title: Quick Mode Buttons entities: - type: button name: Ember Mode icon: mdi:weather-sunset tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "ember slow" - type: button name: Movie Mode icon: mdi:movie-open tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "movie fast" - type: button name: Auto Mode icon: mdi:weather-sunny tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "auto slow" ⸻ 🎚 Example 2: Dropdown Selector This method uses an input_select in HA to choose the mode. You’ll also need an automation to publish the right MQTT payload when the dropdown changes. input_select.yaml input_select: gammy_mode: name: Gammy Mode options: - Ember - Movie - Auto initial: Auto icon: mdi:monitor automation-select.yaml automation: - alias: Gammy Mode Selector trigger: - platform: state entity_id: input_select.gammy_mode action: - choose: - conditions: - condition: state entity_id: input_select.gammy_mode state: "Ember" sequence: - service: mqtt.publish data: topic: "pc/gammy/mode" payload: "ember slow" - conditions: - condition: state entity_id: input_select.gammy_mode state: "Movie" sequence: - service: mqtt.publish data: topic: "pc/gammy/mode" payload: "movie fast" - conditions: - condition: state entity_id: input_select.gammy_mode state: "Auto" sequence: - service: mqtt.publish data: topic: "pc/gammy/mode" payload: "auto slow" dashboard card type: entities title: Mode Selector entities: - entity: input_select.gammy_mode name: Select Mode icon: mdi:monitor ⸻ 🍄 Example 3: Mushroom Cards If you use the Mushroom UI kit, you can make sleek buttons. type: custom:mushroom-template-card primary: Ember icon: mdi:weather-sunset tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "ember slow" type: custom:mushroom-template-card primary: Movie icon: mdi:movie-open tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "movie fast" type: custom:mushroom-template-card primary: Auto icon: mdi:weather-sunny tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "auto slow" ⸻ 🍄 Example 4: Mushroom Chips Row A compact layout with three pill-style chips in one line. type: custom:mushroom-chips-card chips: - type: template icon: mdi:weather-sunset content: Ember tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "ember fast" - type: template icon: mdi:movie-open content: Movie tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "movie fast" - type: template icon: mdi:weather-sunny content: Auto tap_action: action: call-service service: mqtt.publish service_data: topic: "pc/gammy/mode" payload: "auto slow" ⸻ 📊 ASCII Mockup Here’s how the dashboard could look: +-------------------------+ | PC Screen Status | | Current Mode: Ember | +-------------------------+ Quick Mode Buttons: [ 🌇 Ember ] [ 🎬 Movie ] [ ☀️ Auto ] Dropdown Mode Selector: +-----------------------+ | Select Mode: Ember ▼ | +-----------------------+ Mushroom Style: 🌇 Ember 🎬 Movie ☀️ Auto Chips Row (compact): [🌇 Ember] [🎬 Movie] [☀️ Auto] ⸻ ✅ Recommendations • Start with Button Controls to test quickly. • Add the Dropdown Selector if you like compact mode switching. • Switch to Mushroom Cards or Chips Row for a polished look. • Always keep sensor.gammy_mode visible so you know what mode your PC is in.
