Drive Home Assistant straight from MIDI.
The usual ways to get a MIDI cue into Home Assistant mean wiring up Node-RED, scripts, or another always-on server. MIDI-HA Bridge is the direct, turnkey link — no middleman to build or maintain.
Free for a single installation — every feature unlocked.
Built for Proclaim® workflows. Works with any MIDI source.
Turn any MIDI cue into Home Assistant actions.
A macOS menu-bar app that maps the MIDI you already send to Home Assistant scenes, scripts, and devices — no Node-RED, no MQTT, no scripting.
New to Home Assistant? It’s the free, local hub that runs your smart home — lights, scenes, and devices.

See it in action
One slide. The whole room responds.
One MIDI cue, from the slide to the whole room — in about the time it takes to advance a slide.
Demo: Proclaim sends a MIDI note to MIDI-HA Bridge. The app receives it and triggers a Home Assistant scene.
What it does
MIDI goes everywhere Home Assistant goes.
Most ways to drive Home Assistant from MIDI mean building middleware yourself. MIDI-HA Bridge is the direct link — so any MIDI cue you already send can run lights, scenes, scripts, and the rest of your smart building.
Built-in Home Assistant health check.
When a setup doesn't run all week — a church, an event space, a venue between shows — MIDI-HA Bridge watches Home Assistant on its own and emails you the moment it stops responding, with no separate server or uptime service to maintain. That outside watch matters because Home Assistant can't report its own outage. Just as useful for any Home Assistant you don't check every day.
Works with the MIDI you already send.
Proclaim, ProPresenter, Ableton, Logic, QLC+ — anything that emits MIDI. No new hardware and no change to how the operator already works.
One operator runs the room.
Your slides run the room: advance a slide and lights, scenes, and scripts change with it — no separate lighting person or control surface. Whoever runs Proclaim runs the stage too.
Far beyond stage lighting.
Lighting software stops at DMX. Home Assistant runs the whole environment — smart switches, scenes, scripts, projectors, climate, locks, notifications — so one MIDI cue can drive any of it.
Setup
Set up in about a minute.
Everything is configured inside the app — no files to edit by hand. No code. No YAML.
Install
Open the .dmg, drag to Applications, and launch. It appears in the menu bar with no Dock icon.
Connect Home Assistant
Enter your HA address, such as http://homeassistant.local:8123, and a Long-Lived Access Token.
Pick your MIDI port
Leave it on MIDI-HA Bridge — the app’s own built-in port, so there’s no macOS MIDI setup to do.
Map notes to actions
Match each MIDI note to a Home Assistant action: a scene, a script, or anything else you use.

FAQ
Questions, answered.
Do I need to write any code or YAML?
No. The Home Assistant connection, the MIDI port, and every note-to-action mapping are set inside the app. There are no config files to edit by hand.
Does it work without Proclaim?
Yes. It listens to any MIDI source — ProPresenter, EasyWorship, Ableton, Logic, QLC+, or a hardware controller. Proclaim is simply the most common setup it was built for.
What happens if Home Assistant goes down during a service?
The MIDI cue flow keeps running — a failed action just doesn't fire, so the service is never blocked. The app also emails you when Home Assistant stops responding, so you can fix it before the next time you need it.
Does it send my data anywhere? Is it cloud-based?
No. MIDI-HA Bridge runs locally on your Mac and talks only to your Home Assistant over your own network. Email registration is optional, for update and support notices.
How does it connect to Home Assistant?
With your Home Assistant address and a Long-Lived Access Token, over your local network. There are no add-ons or custom integrations to install inside Home Assistant.
Can it trigger more than lights?
Yes. A MIDI note can run anything Home Assistant does — scenes, scripts, smart switches, projectors, climate, locks, and notifications.
Which Macs are supported?
Apple Silicon and Intel Macs. It runs quietly from the menu bar with no Dock icon.
What's the difference between Free and a Business license?
Free covers one installation per local network, with every feature unlocked. Each additional install on that network needs its own Business license — $29/mo or $290/yr per install (2 months free on annual). The first install is always free. A few examples:
- One church, one Mac running MIDI-HA Bridge — Free
- One venue, one controller Mac — Free
- Two Macs on one network — first is Free, second needs one Business license
- Integrator deploying several installs on one network — one Business license per additional install
Can you set it up for me?
Yes. If you'd rather not touch tokens and MIDI ports, we offer remote setup and scene design — see Services. The app and the setup guide stay free either way.
How do I download it?
Grab the latest macOS build from the download page — open the .dmg, drag the app to Applications, and launch it. Then follow the setup guide to connect Home Assistant.
