The wall screen shows the status of your instances at all times on an office or reception TV. Allow five minutes: install the app, pair the screen with your account, then stop the TV from going to sleep.
On this page
Samsung, LG or another system? The app does not exist there: plug in a Google TV box, or open app.tocsin24.com/tv in the browser of the TV, a mini PC or a Raspberry Pi (same pairing screen, same steps).
1. Install the app
- On the TV, open Google Play (Apps tab, then “Search for apps”).
- Search for Tocsin24 and install the app.
- Open it: a six-character code is shown, with a QR code.
2. Pair the screen with your account
The screen shows nothing about your shops until you pair it. The code changes every ten minutes: if it has changed in the meantime, use the new one.
With the QR code (easiest)
- Scan the screen’s QR code with your phone’s camera.
- The “Pair a TV” page of your account opens with the code already filled in (sign in if needed). Check that it matches the one shown on your TV.
- Name the screen (“Reception”, “Office”…), tick the instances to show, then “Pair the screen”.
Without the QR code
- On a phone or computer, open app.tocsin24.com and sign in.
- Menu My account › Screens, Pair a TV card.
- Enter the code shown by the TV, name the screen, choose the instances, then “Pair the screen”.
The TV shows the wall by itself within a few seconds and remembers it: next time it is switched on, it opens the wall straight away. On first display, three tips scroll at the bottom of the screen; press OK to close them. No account yet? On the code screen, press OK to see a demo wall.
3. Turn off sleep mode
The app prevents the screen saver, but no app can stop the TV from switching off to save energy. Set it once and for all; labels vary from one model to another.
- Google TV (Sony, TCL, Hisense, recent Philips, Chromecast, Google TV Streamer): Settings › System › Power & energy › “Turn off display” or “Energy saver”: Never.
- Android TV (Sony, Philips, NVIDIA Shield…): Settings › Device preferences (or System) › Power, “Sleep when inactive” or “Auto power off”: Never or Off. On Philips, also check Settings › Eco settings.
- Box plugged into another TV (Samsung, LG…): set the box as above, and the TV itself: its “auto standby” or “auto power off” (often after a few hours without a remote press) must be turned off, in the power or energy saving settings.
After a power cut, the app restarts by itself if the TV allows it; otherwise, open it once from the home screen.
With the remote
- Long press OK (one second): light theme, dark theme, or the one chosen in your account.
- Back: leaves the app.
- Nothing else to do: the wall updates by itself every 30 seconds and can play a short chime when an instance turns critical (setting in My account › Screens).
Troubleshooting
The screen says "This screen is not authorised on this network"
This screen's IP address filter is on and the TV connects from another address (router that changed address, other network, 4G). The screen shows the address seen by Tocsin24: add it in My account › Screens › edit the screen, or turn the filter off. The wall comes back by itself within 30 seconds.
"Code expired" or the code has changed
A code lasts ten minutes. The TV shows a new one by itself: enter the one on screen when you pair, or scan the QR code again.
The code is refused although it is still on screen
Check the characters: the code never uses 0, O, 1 or I. The dash is optional. A code works only once: if it has just paired a screen, the TV shows a new one.
The screen says "Reconnecting to the server…"
The TV cannot reach Tocsin24: network down, weak Wi-Fi or a platform update. It retries by itself and returns to the wall as soon as the server answers, without you touching anything. If it lasts, check the TV's Internet connection.
The screen says "Access revoked" or asks for a code again
The screen was deleted or its address regenerated in My account › Screens, or its author may no longer show these instances. Pair it again with the code on screen.
The TV switches off after a few hours
That is the energy saving of the TV (or of the TV behind the box): see Turn off sleep mode.
Which language does the screen use?
The TV's language if it is set to French or English. In another language: English before pairing, then the language of the account that paired the screen.
