Hello everyone!
I am incredibly excited to share a project I’ve been developing for Hubitat: Advanced Sonos Controls.
This application was born out of a desire to treat smart home audio the way commercial Building Management Systems (BMS) treat HVAC and lighting—with precision, failsafes, cost tracking, and rock-solid event overrides.
If you are tired of phantom power drain from idle speakers, blown eardrums from 6 AM music starting at 80% volume, TTS announcements that no one hears, or the tedious process of capturing Sonos playlists into Hubitat virtual switches, this app solves all of it in one clean, modular dashboard.
Here is the complete breakdown of what this engine can do:
Live System Dashboard & Target UI
Instead of clicking through individual device pages, the app features a dynamically styled HTML dashboard right inside the preferences page.
- Top-Down View: Instantly see the Power State (Smart Plug), Play Status (Playing, Paused, Stopped, Muted, Event Muted), Current Volume, and exactly what track is playing across all 6 supported zones.
- Active Control Panel: Select a zone from the dropdown to reveal a dedicated "Active Target" mini-dashboard. From here, you get full transport controls (Play, Pause, Prev, Next, Vol Up/Down) as well as Advanced Controls (Shuffle, Repeat, Night Mode, Speech Enhancement).
- Global Emergency Pause All: A giant red panic button at the top of the UI that instantly halts all audio across the entire property with one click.
Smart Power Management & Failsafes
Sonos speakers burn 2 to 7 watts just sitting idle. This app connects your speakers to Smart Plugs to automatically kill power when you don't need them (e.g., Away or Night mode), but it does so safely.
- The Failsafe (Anti-Pop): When the mode changes to power off a zone, the engine intercepts the command, sends a
pause()command to the speaker first, waits for the audio to stop, and then cuts the physical power. No more jarring speaker pops. - Startup Volume Normalization: Set a default volume (e.g., 20%). When the smart plug turns the speaker back on, the app forces the volume to your safe level before it can make a sound.
- Auto-Resume Playback: If enabled, the app waits 60 seconds after a smart plug turns on for the speaker to reconnect to Wi-Fi, then automatically issues a
play()command so your ambient audio picks up exactly where it left off.
BMS-Grade Protection & Event Overrides
This app respects real-world events and protects your hardware.
- Hardware Protection (Volume Clamping): Set a Maximum Volume Cap (e.g., 75%) for a zone. If a user or an automation pushes the volume past that limit, the engine instantly clamps it back down.
- Doorbell Muting: Link your smart doorbell button. If someone rings the bell, the app instantly mutes all currently playing speakers, waits a customizable amount of time (e.g., 30 seconds), and unmutes them.
- Perimeter Door Muting: Link your exterior door contact sensors. If a door opens, playing speakers are muted. When the door shuts, the music resumes.
- Automated Night-Time Sweeps: Set a specific time (e.g., 10:00 PM) and a safe volume (e.g., 15%). The app will sweep the house and lower all speaker volumes, ensuring late-night jump scares are impossible.
- Good Night Override Locks: You can assign a specific virtual switch to any zone. If that switch is ON, the app considers that zone "Locked." It will ignore Mode Power changes, Night Sweeps, and Event Muting so your bedroom white-noise is never interrupted by a door opening.
Dynamic Favorites & Housekeeping
Capturing what is currently playing on a Sonos speaker and turning it into an automation trigger used to be a massive headache.
- 1-Click Virtual Switches: While a song, radio station, or playlist is playing, select the zone in the Control Panel and click “Save Current Track as Virtual Switch.” The app extracts the complex Track URI (even digging into JSON payloads for DLNA tracks) and captures your current volume. It instantly generates a Hubitat Virtual Switch. Turn that switch ON in Rule Machine, and that exact track plays at that exact volume.
- In-App Management: Delete these favorites right from a dropdown menu in the app.
- Auto-Purge Housekeeping: Enable this feature, and the app will run a 3:00 AM sweep every night to automatically delete any Favorite Virtual Switch older than 30 days, keeping your Hubitat database incredibly clean.
Smart Intercom (TTS)
- Auto-Restore Volume: Type a message and set a TTS Volume (e.g., 50%). The app will temporarily adjust the speaker, broadcast your message, and automatically restore the speaker's previous volume 10 seconds later.
Energy Cost & ROI Tracking
- 13 Hardware Profiles: Select your exact Sonos hardware (Arc, Era 300, Beam, Amp, Sub, etc.). The engine knows the exact idle and active wattage of each specific device.
- ROI Dashboard: By monitoring your smart plugs and playback states, the app calculates a rolling 7-day estimate of your power usage in kWh, your estimated utility cost, and your Avoided Idle Power—showing you exactly how much money the app is saving you by managing phantom drain.
Modular & Lightweight Design
- Global Master Switch: Assign a switch to instantly kill the entire application's background processing if you are throwing a party or doing maintenance.
- Module Toggles: Don't care about energy tracking? Don't use Virtual Favorites? Simply toggle them off in the Global Settings. The app will completely hide their UI sections and halt their background scheduled jobs, keeping your hub running lightning fast.
- In-App Action History: View a rolling log of the last 30 actions, mode changes, and TTS broadcasts directly inside the app.
Open Source & Free to Use
This application is completely free and open source. I built this to solve my own smart home audio headaches, and I want the community to benefit from it.
You are free to use it, dissect the code to see how the HTML tables or JSON URI extractions are done, modify it for your own setups, or rip out chunks of the logic to reuse in your own custom Hubitat applications.
