What a signage stick needs
A stick at home sits idle between shows. A stick on a signage screen runs one app from morning to night and nobody stands in front of it, so a small problem lasts until someone walks over. Five jobs keep it dependable:
| Job | How | Who |
|---|---|---|
| Stick software | Settings, My Fire TV, About, Check for System Update | You, on the stick |
| The Player | The Player's Amazon Appstore listing, Update | You, on the stick |
| The cache | Settings, Applications, or a message to your agent | You, or your agent from afar |
| Start on boot | A one-time permission over ADB on Fire OS 8 | You, once |
| Watching the screen | A screenshot after each publish, health reports and alerts | Your agent |
Why a signage stick slows down or runs out of room
A Fire TV Stick is built for watching TV at home, and a signage screen asks different things of it:
- It stores your content. The Player downloads images and video once and replays them from the stick's own storage, which is why a playlist keeps playing when the network drops. The more you publish, the more the stick holds, and Amazon says clearing an app's cache can fix low storage messages.
- It has little memory. Amazon's table lists 1 GB to 2 GB across the sticks, and the Fire TV Stick page puts each model beside its Fire OS and output. A 4K clip needs a stick with 4K output, so match your video to the stick.
- It wants to show its home screen. After a restart, a stick shows its own home screen and other apps unless the Player starts by itself.
- Web pages need the network. A web page or live stream needs the network the whole time it plays, so a weak Wi-Fi signal shows up there first.
Most of what follows removes one of these four.
Update the Fire TV Stick's software
Amazon says Fire TV devices and their accessories download software updates by themselves while they are online. To check by hand:
- On the stick, press Home and open Settings.
- Choose My Fire TV. On some versions it is called Device & Software.
- Choose About, then Check for System Update.
- If an update is waiting, choose to install it. The stick restarts when it finishes.
Amazon lists the latest software version for each Fire TV device on its software updates page, so you can compare it with the version shown under About. Which model you have decides which version it can reach; the Fire TV Stick page lists each stick's Fire OS.
A restart is the one thing a signage stick minds. With Start on boot on, the Player opens again by itself once the stick is back. On Fire OS 8 that depends on a permission granted once over ADB, so check it after a first update: the setup guide shows how.
Update the screenRIG Player
The Player updates through the Amazon Appstore, and the update keeps your pairing. Open the Player's Appstore listing on the stick and choose Update when it is offered. Your agent cannot push a Player update to a Fire TV Stick or to an Amazon Signage Stick: the store does that.
Clear the cache on the stick
Amazon's own steps for one app:
- Press Home and open Settings.
- Choose Applications, then Manage Installed Applications.
- Pick the app, then choose Clear Cache.
Amazon says this can fix intermittent app problems and low storage messages. Newer Fire OS versions also offer Clear all Application Caches under Applications.
Choose Clear Cache and stop there. The next choice, Clear Data, removes the app's saved data as if it had just been installed, and a freshly installed Player shows a pairing code again that you read to your agent.
Clear the Player's cache from your agent
Your agent can clear the Player's cache without anyone touching the stick. It keeps the pairing and the settings, and the Player fills its cache again from your project.
- You
The office Fire TV says Storage low. Clear its cache.
- Agent
Done. I cleared the Player's cache on Office Fire TV. Its pairing and settings are untouched, and it is downloading the playlist again. I checked a screenshot to be sure it is playing.
Your agent reads what a screen can do before it acts. On a Fire TV Stick or an Amazon Signage Stick:
| Remote action | What happens |
|---|---|
| Clear cache | Yes, as above |
| Restart the Player | Where the device lets the Player relaunch itself |
| Update the Player | No: the Appstore updates it |
| Restart the stick | No: unplug it, or use the stick's own Settings |
The Player guide tabulates what every Player reports and switches. A screen whose Player does not offer an action answers that it is unsupported, and nothing is sent.
Keep the Player in front and the stick awake
Start on boot is on by default, so the Player opens by itself once the stick has power. Two settings from the setup guide protect the screen from the stick's own habits:
- Start on boot. On Fire OS 8, grant Display over other apps once over ADB, as in step 5.
- Staying awake. A stick left idle can go to sleep. Two ADB commands keep it awake, as in step 6.
After a restart, a stick with no network still plays its saved content, and the Player picks up new changes when the network returns.
Know when a stick has a problem
Your agent checks a screenshot of the screen after it publishes, so a stick that is stuck on the wrong picture shows up right away. The rest arrives without anyone looking:
- Health reports. The Amazon build of the Player, on a Fire TV Stick or an Amazon Signage Stick, reports uptime, memory, display connection, network and Wi-Fi signal, crashes and renderer restarts every fifteen minutes, and at once when its display connection or power changes. The Player guide lists them.
- Alerts. screenRIG emails the people you choose, or sends a signed webhook to your own service or agent, when a screen goes offline, loses its display, cannot store its content, keeps crashing, or shows a blank or frozen picture. Every project already emails its owner when a screen has been offline for 10 minutes.
| What you see | What to do |
|---|---|
| A Storage low message, or content that stops part way through downloading | Clear the Player's cache, from the stick or from your agent. |
| The stick shows its own home screen | The Player is not in front. Open it from the stick's Apps menu, and check Start on boot. |
| The stick went offline | Check its Wi-Fi. A screen that loses its network keeps playing its saved content. |
| A pairing code appears again | The Player was reset or reinstalled. Read the new code to your agent. |
Frequently asked questions
How do I keep a Fire TV Stick running as a signage player?
Let the stick install Amazon's updates, update the Player from its Appstore listing, clear the Player's cache when storage runs low, and keep Start on boot on. Your agent checks the screen after every publish and tells you when a stick goes offline.
How often does a Fire TV Stick update?
Amazon sends software updates as it releases them, and a stick that is online downloads them by itself. Checking by hand under Settings, My Fire TV, About, Check for System Update installs one that is waiting.
Does clearing the cache delete my content or my pairing?
No. Clearing the Player's cache keeps its pairing and settings, and the Player downloads your content again from your project. Clear Data is the choice that resets the app.
Will the Player start by itself after the stick updates?
Yes, when Start on boot is on. On Fire OS 8 it needs a permission granted once over ADB. The setup guide has the steps.
