# Hearth

> Hearth is an open-source universal TV remote that finds the LG, Samsung, Roku, Google TV and Apple TV devices on your home Wi-Fi and gives every phone in the house a fast remote. It runs on an always-on computer in your home (such as a Mac mini, an old laptop or a Raspberry Pi) with Node.js, and any phone or browser on the same Wi-Fi opens it, with no accounts, codes or cloud in between. Features include a swipe pad, volume, an app shelf, inputs, messages on screen, opening an app on every TV at once, and one button that turns every TV off. A public demo with pretend TVs runs at mutaafaziz.com/hearth/demo/, and an iPhone app is described as coming soon to the App Store. It is MIT-licensed and made by Mutaaf Aziz.

## FAQ

### Is Hearth free?

Yes. Hearth is open source (MIT) and free to run on your own computer. An iPhone app is described as coming soon to the App Store, with the first TV free.

### Which TVs does it work with?

LG webOS (2014+), Samsung Tizen (2016+), Roku players and TVs, Google TV / Android TV (over Cast, with a limited set of controls), and Apple TV (tvOS 15+). The README has a full table of what works on each.

### How do I set it up?

Install Node.js 20.19 or newer on a computer that's usually on, run npm run up in the hearth folder, then open the link it prints on a phone on the same Wi-Fi and follow the setup screens.

### Does Hearth send my data to the cloud?

Your TVs, pairing keys and settings stay on your home network. Hearth talks to TVs directly on your Wi-Fi with no account. Optional features such as connection help or reading a power bill send only limited, scrubbed details, and you see them first.

### Does Hearth show ads?

The Hearth on your home network and the Hearth app never show ads. Only the public demo on mutaafaziz.com, with pretend TVs, shows a small banner under it.

### Can I try it without installing anything?

Yes. The demo at mutaafaziz.com/hearth/demo/ runs the real interface against pretend TVs.

### Do I need an account to use Hearth?

No. Hearth runs on your home network with no accounts, codes or cloud in between. Any phone or browser on the same Wi-Fi opens it.

### What do I need to run Hearth?

An always-on computer in your home, such as a Mac mini, an old laptop or a Raspberry Pi, running macOS or Linux with Node.js 20.19 or newer, and a supported TV on the same Wi-Fi.

### Is Hearth a free alternative to a Logitech Harmony remote?

For the TVs and streamers on your Wi-Fi, yes: Hearth is free and open source, runs on a computer already in your home, and turns any phone on the same network into a remote for LG, Samsung, Roku, Google TV and Apple TV devices. It works over the network, so devices without a network connection are not covered.
