Testing and evidence
How we test TV compatibility
Every platform TV Remotely supports is tested against a simulated TV that speaks that platform’s control protocol. Three physical TVs have been tested so far: two Samsung sets and one Sony. We only name a TV model as tested when it has actually been tested, and we say so when a platform has not been checked on real hardware yet.
This page explains what that means for your TV. The compatibility table gives the short answer for each platform.
Two kinds of testing
Physical TVs. A real set on a home network, checked for discovery, pairing, navigation keys, volume, app launching and reconnecting. Results are recorded against the exact model number, because the same brand can behave differently from one model year to the next.
Simulated TVs. For each platform, the app’s repository has a small program that behaves like that brand’s TV on the network: it announces itself, asks for approval or a PIN, and answers commands the way the real protocol does. The app is run against these simulators on phones and emulators to check that pairing and every key type behave correctly, and to reproduce bugs reported from real TVs.
A simulator checks that the app follows the protocol. It cannot show what a particular manufacturer’s firmware actually does, so a platform tested only in simulation is described as a protocol target, not as verified.
What has been tested, platform by platform
| Platform | Physical models tested | Simulator | What that means |
|---|---|---|---|
| Samsung Tizen | UA55NU7100 (2018), UA55CU7000 (2023) | Yes | Other model years, including 2024 to 2026, are protocol targets. |
| Sony BRAVIA | KD-65X9000E | Yes | Recent BRAVIA and Google TV sets are protocol targets. |
| LG webOS | None recorded | Yes | webOS 3 and later are targets. A pairing failure reported on webOS 6 was reproduced in the simulator and fixed. |
| Roku | None recorded | Yes | Uses Roku’s local control protocol (ECP). Roku TVs and Roku players behave differently for power and volume. |
| Android TV / Google TV | None recorded | Yes | Needs the v2 remote service. Older v1-only sets are not supported. |
| Amazon Fire TV | None recorded | Yes | Uses developer ADB access with approval on the TV. Vega OS devices will not connect. |
| Hisense VIDAA | None recorded | Yes | Experimental. Newer firmware may authenticate differently from the simulated version. |
| Vizio SmartCast | None recorded | Yes | PIN pairing as intended; not yet confirmed on hardware. |
What “supported” promises, and what it doesn’t
- Supported means the app implements that platform’s control protocol and passes its simulator checks. It does not guarantee that every model, firmware version or network will work.
- Partial or experimental means some functions may be missing, or that newer firmware is known to work differently.
- Detected but not controllable means the app can see a device on the network, but that device offers no control protocol the app can use. Amazon’s Vega OS devices are the current example: the app recognises them and says plainly that it can’t control them yet, rather than failing with an error you can’t act on.
- A key that works on one platform may not exist on another. For example, some TVs don’t accept volume commands over the network when the sound goes to an external speaker. See volume not working.
How your reports change this page
When a TV doesn’t work as described, a report with the model, firmware version, app version and the exact command that failed is the most useful evidence we can get. Reports are answered in public on the support board, and fixed issues are listed under recent fixes.
When a new physical model is tested, it is added to the table above and to the matching brand guide. A platform moves from “protocol target” to tested only on a recorded hardware result, never on a reasonable guess.

Last reviewed 19 October 2026. TV makers change their control protocols with firmware updates, so a result can go out of date; the terms explain that compatibility can’t be guaranteed.
