Give Every Till Its Own Hardware - Not a Shared Guess
Printer, customer display, barcode scanner, and scale - each one assigned by name to the exact till it belongs to, so a busy counter never grabs the wrong device.
Set the hardware up once from the back office; from then on, your cashiers just ring up sales.

Key Features
Assign Hardware Per Till, Not Per Box
Pick exactly which receipt printer, customer display, barcode scanner(s), and electronic scale this till uses on its connected IoT Box, so one box can safely serve several tills without devices conflicting.
Set Up Hardware From the Settings App Too
The same IoT Box and device pickers, reachable from the general Settings app - switching boxes resets the four device pickers so a stale link is never carried onto a different box.
Route Kitchen and Bar Tickets to the Right Printer
Link an order printer to one specific, named IoT device instead of leaving it to whichever printer the box happens to find first.
Know Which Till Owns Which Device
Open any IoT device and see, read-only, exactly which till it is currently assigned to - useful for tracing where a device actually went.
No Two Tills Fight Over the Same Scanner or Display
A barcode scanner or a customer display can belong to only one till at a time, and that rule holds no matter which screen, record, or import makes the change.
Cashiers Ring Up Sales. They Don’t Manage Hardware.
A cashier holding only the ordinary Point of Sale role opens their shift and finds the assigned hardware already there and working - no separate IoT administrator access required.
Your IoT Box’s Pairing Details Never Reach the Shop Floor
The till’s browser never receives the IoT Box record itself - only a short, fixed list of device details is ever sent down to the till.
Receipts and the Cash Drawer, on the Printer You Chose
Every receipt, and every cash-drawer-open action, goes to the specific printer assigned to this till - addressed by that printer’s own identity.
Every Connected Scanner Feeds the Till Directly
Each barcode scanner assigned to this till streams its scans straight into the sale as they happen - a till running more than one scanner is never limited to a single shared feed.
Customers Watch Their Own Order Build, Live
The running order and total appear on the customer-facing display assigned to this till, and the till knows whether that display is actually connected.
A Scale That Doesn’t Answer Doesn’t Stall the Sale
Weight comes from the specific electronic scale assigned to this till - live or on demand - and a scale that does not respond does not stall the sale.
From a Paired Box to a Printed Receipt
Pair the box, once.
Your IoT Box and the printer, scanner(s), display, and scale connected to it get paired and registered - a one-time setup step that happens before any till is involved.
Assign the devices to this till.
A Point of Sale manager opens this till’s settings (from the till itself, or from the Settings app) and picks exactly which of those paired devices belong to this specific till. No separate IoT administrator access is needed for this step either.
A cashier opens their shift.
Holding nothing but the ordinary cashier role, they start a session, and the hardware assigned to that till is already there, already working.
A sale happens.
A barcode scans in from the assigned scanner. The customer watches their order build on the assigned display. A scale weighs a loose item without holding up the sale if it doesn’t answer. The receipt - and the cash drawer - come from the assigned printer. If it’s a kitchen or bar order, the ticket finds its own way to the correct order printer too.
Assign Hardware Per Till, Not Per Box
From this till’s own Point of Sale settings, pick exactly which printer, customer display, barcode scanner(s), and electronic scale it uses on your connected IoT Box. The connection address fills in the moment you pick the box and locks in place after that, so there’s only ever one place that sets it - and one IoT Box can safely serve several tills without their devices getting in each other’s way.
Set Up Hardware From the Settings App Too
Prefer working from the general Settings app instead of the till’s own configuration screen? The same box and device pickers are right there. Switch to a different box and the four device choices reset automatically, so a till is never left running on a device link that actually belongs to another box.
Route Kitchen and Bar Tickets to the Right Printer
Point an order printer at one specific, named device instead of leaving it to land on whichever printer the box happens to find first - what a shop needs the moment it runs more than one order printer off a single IoT Box. Cashiers can see how a printer is set up; only a manager can change it.
Know Which Till Owns Which Device
Open any IoT device and see, read-only, exactly which till (or tills) it’s currently assigned to - useful the moment a device stops showing up where you expect it, so you can trace where it actually went instead of guessing.
No Two Tills Fight Over the Same Scanner or Display
A barcode scanner or a customer display can belong to only one till at a time, and that rule holds no matter how the change is made - from the till’s own settings, from the device’s own record, or through a data import. Your receipt printer and your scale are more relaxed: either can happily serve more than one till off the same box.
Cashiers Ring Up Sales. They Don’t Manage Hardware.
A cashier holding nothing but the ordinary Point of Sale cashier role opens their shift, and the printer, scanner, display, and scale already configured for that till are simply there and working - no separate IoT administrator access required. A Point of Sale manager gets the same treatment for their own till’s settings. Your shop keeps its hardware setup screens for the people who should be touching them, and its tills open to everyone who needs to sell.
Your IoT Box’s Pairing Details Never Reach the Shop Floor
The till’s browser never receives the IoT Box record itself - not its pairing token, not its communication channel. Only a short, fixed list of device details is ever sent down to the till. What never leaves the back office can’t leak from the counter.
Receipts and the Cash Drawer, on the Printer You Chose
Every receipt, and every cash-drawer-open action, goes to the specific printer assigned to this till - addressed by that printer’s own identity, not “whichever printer the box finds.”
Every Connected Scanner Feeds the Till Directly
Each barcode scanner assigned to this till streams its scans straight into the sale as they happen. A shop running more than one scanner on a till isn’t limited to a single shared feed - every scanner assigned to that till is live.
Customers Watch Their Own Order Build, Live
The running order and total appear on the customer-facing display assigned to this till, updating as items go in - and the till knows whether that display is actually connected, rather than just assuming it is.
A Scale That Doesn’t Answer Doesn’t Stall the Sale
Weight comes from the specific electronic scale assigned to this till, either as a live stream or as a fresh one-shot reading you request on demand. If that scale isn’t responding, the sale keeps moving instead of freezing while the till waits on it.

Note
Extends viin_iot - see its documentation.
Pos IoT connects the receipt printer, barcode scanner, customer display and electronic scale on a paired IoT box to one specific Point of Sale, so a shop can run several tills off a single box without their hardware getting in each other's way.
Setting the hardware up is a one-time job for a Point of Sale manager or an IoT administrator. A cashier holding only the ordinary Point of Sale cashier role never opens any of the screens below - once the hardware is assigned, it is simply there the next time they open their shift.
Installation
Pos IoT has no menu of its own. It depends on both Point of Sale and Internet Of Things, and Odoo installs it automatically the moment both of those are already installed - there is nothing to install by hand in that case.
To confirm it is installed, or to install it directly:
- Open Apps.
- Remove the Apps filter shown in the search bar, then search for Pos IoT (technical name viin_iot_pos).
- Click Install if it is not already installed.
Configuration
Roles
Two different people touch this module, and only one of them needs any special access:
- A Point of Sale manager or an IoT administrator picks which IoT Box and which devices a till uses - a one-time setup step, done from the screens below.
- A cashier holding only the ordinary Point of Sale cashier role never opens these screens at all - once the hardware is assigned, it is just there the next time they open their shift.
Assigning hardware to a till
Open Point of Sale ‣ Configuration ‣ Point of Sales, then open a till's own form. Its IoT Box section is where the hardware for this specific till is picked:
- IoT Box - the paired box this till talks to. Its IP address fills in automatically the moment you pick it, and stays read-only afterwards.
- Receipt Printer - the one printer on the box that prints this till's receipts and opens its cash drawer.
- Barcode Scanners - every scanner on the box that should feed scans into this till. A till can use more than one.
- Customer Display - the screen that shows the running order to the customer.
- Electronic Scale - the scale this till reads a weight from.
- IoT Devices button - jumps to the full device list for this till's box.
A barcode scanner or a customer display can only be picked on one till at a time - if you try to assign one that is already in use elsewhere, Pos IoT stops you and asks you to free it up first. The receipt printer and the electronic scale are more relaxed: several tills may share the same one off the same box.
Your IoT Box's own address and credentials never leave the back office - the till only ever receives the specific devices you assigned to it here.
Assigning hardware from Settings
The same pickers are also reachable from Settings ‣ Point of Sale, under Connected Devices ‣ IoT Box. Pick the till at the top of the page first, then fill in the same fields:
Switching to a different box here clears the four device pickers, so a till is never left running on a device that actually belongs to another box.
Linking a kitchen or bar printer to a device
Open Point of Sale ‣ Orders ‣ Preparation Printers and open (or create) a printer that prints orders to the kitchen or the bar. Set its Printer Type to Use a printer connected to the IoT Box, then pick the exact device in IoT Device:
Device Identifier fills in on its own from the device you picked. Naming the device this way lets one box drive more than one order printer - useful the moment a shop needs a separate kitchen printer and a separate bar printer off the same box. A cashier can see how a printer is set up; only a Point of Sale manager can change it.
Checking which till a device is assigned to
Open IoT ‣ Devices, then open a device's own page and click its Point of Sale tab:
The list is read-only - it exists so you can trace where a device went the moment it stops showing up on the till you expected.
Usage
Opening a session on a configured till
A cashier opens Point of Sale, then clicks New Session on the till's own card. No IoT access is needed for this - the ordinary Point of Sale cashier role is enough.
Hardware status while selling
The till's own header shows whether its assigned hardware is reachable, right next to the cashier's name:
- A Proxy badge shows whether the till can currently reach its IoT Box at all. Click it to retry the connection.
- A Customer Screen badge shows whether the assigned customer display is connected, separately from the box itself.
None of this depends on real hardware to keep working: on the machine this guide was written from, no physical IoT box was connected and every device showed Disconnected - the till still opened normally and sold products, it simply reported the hardware as unreachable instead of pretending it was there.
What a cashier sees at the till itself once a printer, scanner, display or scale actually answers is specified behaviour this guide could not demonstrate on real hardware:
- A configured receipt printer prints the receipt and opens the cash drawer for this till.
- A configured barcode scanner feeds every scan straight into the current sale.
- A configured customer display shows the running order to the customer.
- A configured electronic scale supplies a weight without freezing the sale if it does not answer.
Troubleshooting
A barcode scanner or customer display cannot be picked on this till. It is already assigned to another till. Free it from that till's own IoT Box section (or from the device's own Point of Sale tab) before assigning it here.
A till's Proxy badge shows Disconnected. The till cannot currently reach its IoT Box. Click the badge to retry, and check that the box itself is powered on and reachable on the network - see the Internet Of Things (IoT) module's own Troubleshooting section for the box side of this.
Switching a till's IoT Box does not keep the old printer, scanner, display or scale. This is expected: changing the box clears the four device pickers, since a device from the previous box is very unlikely to also exist on the new one.
A kitchen or bar printer never receives orders. Confirm its Printer Type is set to Use a printer connected to the IoT Box and that IoT Device points at the exact device meant to print that order.
FAQ
Does a cashier need any IoT access to use the till's hardware? No. Once a Point of Sale manager or an IoT administrator has assigned the devices, an ordinary cashier just opens their shift and the hardware is there.
Can one IoT Box serve more than one till? Yes for the receipt printer and the electronic scale - several tills may share one. A barcode scanner or a customer display, however, can only belong to one till at a time.
Where do I pair the IoT Box itself? That happens in the Internet Of Things (IoT) module, before this module's own screens are used - see its documentation.
Can more than one order printer run off the same IoT Box? Yes - link each order printer to its own device under IoT Device in Preparation Printers.
