Hisense ships TVs with four different operating systems — VIDAA,
Roku TV, Google TV, and Fire TV. The official "Remote for Hisense
TV" you find in their app store only works with VIDAA. When I lost
my own remote, I had a Google TV-flavored Hisense, so I built a
single-app solution that pairs with whichever platform the user has.
Here's how each of the four local-network protocols works, and how
the app picks the right one without asking the user.
TL;DR
| Platform | Local protocol | Pairing |
|---|---|---|
| VIDAA | MQTT over TLS | Direct local connection |
| Roku TV | ECP over HTTP | Open by default on port 8060 |
| Google TV | gRPC, TLS) | 4-digit PIN |
| Fire TV | ADB-over-Wi-Fi | One-time TV-side prompt |
All four are LAN-only — no cloud involvement once paired.
1. VIDAA — MQTT over TLS
VIDAA TVs accept TLS connections on port 36669 and speak MQTT
underneath. The control message format publishes button presses as
small JSON payloads — {"key": "KEY_VOLUMEUP"} etc. — to predictable
topics scoped by the TV's MAC address. Other developers in the Home
Assistant community have written about this in detail; my Swift
implementation is on top of that prior work.
2. Roku TV — ECP is HTTP
Almost too easy. Roku publishes the External Control Protocol
publicly. Every Roku and Hisense Roku TV listens on port 8060:
curl -X POST http://192.168.1.100:8060/keypress/Home
curl -X POST http://192.168.1.100:8060/keypress/VolumeUp
curl http://192.168.1.100:8060/query/active-app
curl http://192.168.1.100:8060/query/device-info
curl -X POST http://192.168.1.100:8060/launch/12
No pairing. No PIN. If your phone and the TV are on the same LAN,
you can drive it from a curl one-liner. This is why I shipped an
in-browser Roku remote at hiremote.app/hisense-roku-tv-remote#remote
— for Hisense Roku TV owners, you don't actually need an app at all.
3. Google TV — gRPC dance
Google TV uses gRPC over TLS with cert pinning. Pairing exchanges a
4-digit PIN through paired proto messages — the Android TV Remote v2
protocol. The .proto definitions are discussed in various developer
communities; from there it's standard gRPC client work.
4. Fire TV — ADB-style local connection
Fire TV runs Android and supports network-mode ADB on port 5555.
After the user enables developer-friendly settings on the TV, the
app authorizes once via a permission prompt on the TV screen.
Platform detection via mDNS
The app browses for service types:
- _androidtvremote._tcp → Google TV
- _roku-rsp._tcp → Roku TV
- _amzn-wplay._tcp → Fire TV
- Port-scan port 36669 fallback → VIDAA
The first responder wins. The user never picks "what kind of Hisense
TV is this" unless detection fails.
The implementation ships as Remote for Hisense TV on the App Store,
free with a Pro tier for the Apple Watch app and Lock Screen widget.
Happy to answer iOS protocol questions in the comments.
