LoRaWAN Gateway – OxBase
In an open environment, the range can be up to 10-15 km. In dense urban or indoor environments, it is generally between 500 m and 2 km, depending on obstacles and antenna positioning.
No. Our gateway has an embedded LoRaWAN server. This means it can operate autonomously, without relying on the Internet or an external server. LoRaWAN sensors are managed locally, and data can be transmitted directly to BMS systems via MQTT, Cloud or other compatible protocols.
Absolutely. A LoRaWAN gateway can manage up to 150 sensors simultaneously, depending on the message frequency (duty cycle) and throughput (Spreading Factor).
Usually via the IP address of the gateway (default 192.168.1.254). You can access it locally via a web browser. The default identifiers are provided in the documentation.
No. All the sensors compatible with our gateway have been integrated and pre-decoded by our team. This means you don’t need to program the frames – simply set the sensor’s LoRaWAN identifiers (DevEUI, AppKey…).
A selection of validated sensors is available directly from the gateway interface, via a dedicated navigation menu. This list is not exhaustive: we can add new sensors on request.
👉 This choice has been made to save you time and avoid any complex technical handling on the customer side.
12 VDC to 24VAC, 15W. Check the data sheet for more details on the OxBase page.
Provide a watertight enclosure with ventilation and a secure power supply.
Yes, it supports TLS, secure authentication and firmware updates from the web page. Remember to change the default identifiers on installation.
SPEGA products -Sistema range
The Sistema (e.control) range is designed for multi-sector control in commercial buildings: thermal comfort, lighting, blinds and shutter management. With more than 340,000 controllers installed since 2010, it has proved its robustness and reliability on more than a million m².
Each project can combine different control modules according to its business needs: HVAC, lighting, solar protection, etc.
The range includes universal controllers, DALI, SMI, EnOcean, MP-Bus modules, etc., all of which are fully interoperable via open protocols such as BACnet IP, LON, DALI and SMI.
This modular architecture means they can be finely tuned to the building, whether for new build or renovation.
Yes, the system is based on clear and powerful LNS plugins, available for all versions of LNS, whatever the operating system.
This guarantees universal integration and a fluid experience, without complex coding. The functional objects are already integrated and tested at the factory: the integrator only has to configure, not program.
The e.control controller complies with the EN 15232 class A standard (the highest level of energy efficiency in BMS). Thanks to intelligent coordination of heating, ventilation, air conditioning, lighting and blinds, energy savings of up to 35% are possible – without compromising comfort.
It’s a solution that pays for itself quickly and lasts.
The system natively exposes BACnet IP and LonMark objects, without requiring any programming on the supervision side.
The e.control Designer tool even automates the creation of BACnet objects, room by room, according to the building plan, saving hours of manual configuration.
Yes, the e.control system is natively multiprotocol:
– LON: ideal for large control networks,
– BACnet/IP: for supervision and global control,
– DALI / SMI: for lighting and blind management,
– EnOcean: for wireless solutions (particularly for renovation),
– MP-Bus: for VAV or fan coil actuators.
Each protocol is integrated without a gateway, guaranteeing total interoperability.
Yes, the system works with both wired and radio (EnOcean), and offers distribution boxes for each room.
These solutions are ideal for renovations in occupied environments (offices, hotels, hospitals, etc.) where intervention time is reduced, without sacrificing performance or comfort.
– e.control Designer: a graphical tool based on the building plans, enabling you to modify, test, move or duplicate rooms in just a few clicks.
– Integrated diagnostics: status of all equipment visible at a glance, management of alarms and errors (lights out, blinds blocked, etc.).
All with a unified interface, whatever the protocol used.
Yes, all functional objects are VDI 3813 standardised, factory-tested and interoperable (LonMark).
The system is designed to be reliable, maintainable and scalable, with functional uniformity across all devices – making it easy to maintain even complex or multi-builder sites.
Router – Oxtopus
The Oxtopus router connects wired Lon, IzoT™, Modbus or BACnet MS/TP networks to an IP infrastructure. It acts as a multiprotocol gateway, translating twisted-pair (TP/FT10) signals to IP, making it easy to integrate field equipment into a supervision system.
No. The router performs native routing, without the need for complex programming. For Modbus, for example, it provides access to all the registers of all the equipment simply by addressing the right slots. This considerably reduces engineering effort during commissioning.
Yes. The Oxtopus can simultaneously manage Lon/IzoT™, Modbus RTU and BACnet MS/TP depending on the model. This makes it possible to federate several protocols in a single box, simplifying the BMS architecture and reducing the amount of equipment to be installed.
Yes. Using IzoT™ technology, the router is 100% compatible with existing LonWorks installations while opening up access to IP. It allows the re-use of traditional Lon configuration tools, while offering native BACnet/IP or IP communications.
The Oxtopus router incorporates the 802.1x protocol, enabling secure authentication over Ethernet. This protects access to IP networks and ensures compliance with the building’s IT security policies.
Yes, it consumes less than 6W and can manage up to 250 Lon devices, or 120 via Modbus or BACnet. What’s more, the Scheduler option lets you control equipment locally via time schedules, reducing consumption by up to 30% without the need for an additional PLC.
Each protocol has statistics which can be consulted via the router’s web pages or on Modbus/IP. In the event of an outage or disturbance, fault LEDs on the front panel immediately indicate the status of the bus. This makes commissioning and maintenance easier.
IzoT™ is the evolution of the Lon protocol, designed to make equipment natively IP compatible, while remaining 100% backward compatible with existing Lon installations. It allows traditional Lon products and IzoT™ equipment to coexist on the same twisted pair, without a gateway.
Thanks to IzoT™, supervision can dialogue indifferently in Lon or BACnet/IP, which simplifies engineering and future-proofs installations.
L’OxBras est un switch/routeur administrable sécurisé, conçu pour les réseaux IP de la GTB. Il permet de connecter, superviser et sécuriser les équipements GTB (Lon, BACnet, Modbus, etc.) en IPV4 ou IPV6, tout en assurant une redondance réseau et un contrôle d’accès fin.
Oui. L’Ox-Bras s’intègre aussi bien dans des architectures existantes que nouvelles, grâce à ses ports RJ45 et SFP. Il permet d’ajouter de la cybersécurité et de la résilience réseau sans remettre en cause l’existant.
Non. L’Ox-Bras propose une configuration simplifiée via une interface Web, avec possibilité d’import/export CSV. Il gère automatiquement l’adressage des équipements (DHCP local), et les noms DNS facilitent leur identification sans devoir manipuler des adresses IP complexes.
Oui. Il intègre :
– 802.1x pour le contrôle d’accès,
– gestion fine des VLAN (802.1Q),
– filtrage par adresse MAC pour les équipements non compatibles VLAN,
– une puce sécurisée pour le stockage des certificats,
– des algorithmes cryptographiques avancés (SHA-256, ECDSA, etc.).
C’est une solution conçue pour protéger nativement le réseau GTB contre les intrusions ou erreurs de configuration.
La configuration Ox-Bras permet un fonctionnement en grappe (cluster). Si un routeur “maître” tombe, un autre routeur de la grappe prend automatiquement le relais selon un ordre de priorité. Cela garantit la continuité des services critiques comme le routage, les VPN ou le serveur de configuration.
Oui. Il offre :
– un scannage automatique des équipements sur les boucles d’étage,
– le monitoring SNMP, y compris SNMPv3,
– des statistiques de bande passante par protocole,
– le port forwarding vers Wireshark pour l’analyse réseau avancée.
C’est un véritable outil de diagnostic pour les intégrateurs, aussi utile en phase de mise en service qu’en maintenance.
L’OxBras dispose d’un écran tactile couleur avec un résumé graphique de l’état du réseau. Il intègre également une puce NFC, permettant une authentification rapide et une sécurisation de l’adresse IP.
Il prend en charge :
– DHCP serveur (par étage ou par boucle),
– DNS serveur local (pour nommer les équipements),
– Spanning Tree (STP, RSTP, MST) pour la redondance réseau,
– IGMP Snooping pour le multicast,
– NTP pour la synchronisation horaire réseau.
Seulement 12 VA, malgré sa puissance de calcul (dual core + secure element) et ses 8 ports RJ45 + 2 SFP. Il est parfaitement adapté aux armoires techniques, sans ventilation, donc silencieux et éco-énergétique.
