PART 1 — Analytical Summary 🚀
Context 💼
This session is led by Louie from Odoo’s R&D IoT team, explaining how to integrate hardware with the Odoo IoT Box and when to avoid it. The talk walks through architecture, development patterns (interfaces/drivers), networking protocols, and practical debugging and operations. It closes with a Q&A touching on device limits, payment terminals, subscription, and reliability (notably for Belgian “black box” fiscal devices). This matters because many Odoo deployments depend on printers, payment terminals, scales, kiosks, and fiscal boxes that browsers cannot reach natively — and the IoT Box is Odoo’s solution of last resort to bridge those gaps.
Core ideas & innovations 🧠
The first principle is restraint: only use the IoT Box when no simpler integration exists. If a device exposes a cloud API, integrate directly with Odoo from the database; using a box adds network complexity, more code surface, and potential security risk. When you must use it, the IoT Box is a Raspberry Pi running a customized Debian image (e.g., latest “YY.MM” build such as 25.07). Notably, /c/var and /tmp are tmpfs to spare the SD card; the Odoo runner on the box is a sparse checkout with controlled updates.
Architecturally, the IoT service splits into a core and IoT handlers. The core manages lifecycle: starting interfaces, spawning drivers, keeping the box’s code aligned with the connected database version (e.g., SaaS 18.4 vs. 17), downloading any custom IoT handlers (interfaces/drivers) from the database, sharing discovered devices with Odoo, and routing actions/events. Handlers are in two layers: an interface per connection type (USB, serial, network, etc.) continuously detects devices and filters supported ones; then a driver runs per device to communicate with the hardware and expose callable actions back to Odoo.
Developers implement integrations by adding an iot_handlers folder to their module with two subfolders: interfaces and drivers. An interface class (inheriting from the base Interface) declares a connection type and overrides get_devices to return a dictionary containing at least a name and a unique identifier. A driver class (inheriting from the base Driver) exposes the device’s actions via a map of action names to methods; returns can be the newer “return dict” style or the older data["result"]. When an action is called from Odoo, the service dispatches to the right method and automatically emits an event back.
On the app side, use the IoT HTTP service from JavaScript to invoke device actions: pass the device record ID, its identifier, and payload. The service automatically negotiates transport, trying WebRTC, then long polling, then WebSocket. Because the Odoo server usually isn’t on the device’s LAN, backend request.post/get won’t reach the box; for server-side messaging, use the IoT Channel model’s send_message (via WebSocket). This layered protocol strategy increases resilience across diverse network topologies without extra developer work.
Debugging is practical: the box sends logs to the database in small batches, so you can inspect them centrally. SSH access works locally to the box’s IP (user pi), and for remote cases you can spin up a secure tunnel (ngrok token) from the IoT Box homepage; in v19 you can initiate this directly from the database UI via the IoT app (debug mode). Helpful CLI aliases let you restart services, show logs/config, switch branches if an update misapplies, and use dev tools to freeze handler downloads/updates or selectively enable/disable actions for safe testing.
Impact & takeaways ⚙️
This approach makes hardware integration with Odoo both structured and constrained. The IoT Box standardizes how to detect devices, encapsulate protocols, and expose safe actions to Odoo, while the dynamic download of IoT handlers from the database keeps field devices synchronized to module logic. The multi-protocol fallback (WebRTC → long polling → WebSocket) improves reliability. Remote-debugging from the database in v19 shortens support cycles. Most importantly, the team insists on using cloud APIs whenever possible to reduce complexity, improve maintainability, and minimize security exposure.
Notable Q&A highlights 💬
- Preference for API-first: no plans to broadly expand IoT Box-native integrations like LoRaWAN; push for cloud/API integrations when feasible.
- Payment terminals: one payment terminal per IoT Box is the current limitation; plan deployments accordingly (e.g., one box per register-terminal pair).
- Device counts: limited by USB ports for USB devices; network devices are theoretically unlimited.
- Multiple boxes on a network: prior de-duplication of network devices caused confusion; now devices are shown per box (fix backported from v16+).
- Custom drivers: fully supported — add IoT handlers to your module; boxes download them when connected to that database.
- Virtualization: a “virtual” IoT Box on a Windows server is possible; physical boxes are paid, virtual is free, but subscription is based on the number of connected boxes (Linux vs. Windows counted).
- Networking tip: set a static IP via your router’s DHCP reservation using the box’s MAC address.
- Reliability (Belgian fiscal “black box”): stability has improved after multiple fixes; flash the latest image and re-pair after migrations; poor-quality cables often cause issues.
PART 2 — Viewpoint: Odoo Perspective

Simplicity is our compass. The IoT Box exists for the edge cases where browsers and cloud APIs can’t reach — not as the first tool you grab. When a device has an API, integrate from the database and keep the stack lean. Every removed layer is one less place for bugs, configuration drift, and security issues.
When you do need the box, it should feel invisible: unified interfaces and drivers, automatic version alignment with the database, and resilient transports that “just work.” The community’s power is in shared patterns — small, well-crafted handlers that we can all maintain together. Our job is to make the hard parts boring, so teams can focus on outcomes, not plumbing.
PART 3 — Viewpoint: Competitors (SAP / Microsoft / Others)
Disclaimer: AI-generated fictional commentary. Not an official corporate statement.
Odoo’s stance to favor API-first integrations over edge hardware proxies is sensible; it reduces risk and accelerates lifecycle management. The IoT Box architecture — lightweight handlers, per-device drivers, and protocol fallbacks — provides a pragmatic bridge for SMB and midmarket scenarios where legacy peripherals are common.
For large enterprises, the challenges shift: device fleet governance at scale, compliance (e.g., fiscal devices, payment certifications), and zero-trust networking across segmented sites. Centralized update orchestration, audit trails, and granular policy control become critical. Odoo’s model is getting there, but enterprises will scrutinize multi-site observability, high-availability options for retail lanes, and the one-terminal-per-box constraint. UX is strong; depth around compliance operations and massive fleet management will determine adoption in complex environments.
