ZENNER IoT GatewayPLUS Indoor – Powerful Indoor Gateway with LoRaWAN® Network
Last modified on 3rd December, 2024
As announced in the article about the ZENNER IoT Gateways, after the ZENNER IoT GatewayPLUS SMART, today we are presenting the ZENNER IoT GatewayPLUS Indoor in detail. What distinguishes this Gateway? What are advantages but also limitations? For whom and for what use cases is it suitable? This post provides you with answers to these questions.
The Gateway
As the name suggests, the ZENNER IoT GatewayPLUS Indoor is a powerful and compact indoor gateway. It is ideal for establishing LoRaWAN® connectivity in buildings and in the building environment in order to receive the values of hard-to-reach sensors (heat cost allocators, smoke detectors, water or heat meters, room sensors and much more) on several floors including basements, without the need for an additional repeater. The GatewayPLUS Indoor has already been installed in several thousand LoRaWAN® system installations of the Minol-ZENNER Group and is an integral part of many Minol-ZENNER IoT system solutions.
What is special about this gateway, in addition to its attractive price, is that it automatically connects to the Gateway Management System (GMS) ZENNER Datahub as soon as the power supply is available after installation/assembly. So you don’t have to worry about storing the gateway in the system before commissioning. A connection to the backend is possible both via mobile radio (thanks to the integrated SIM card) and via Ethernet, and the gateway impresses with its compactness and the deliberately simple design. This means that it is hardly noticeable in its surroundings and is less susceptible to damage from vandalism .

Benefits & Limitations
In addition to the special features just mentioned, the following advantages should be mentioned with this IoT gateway:
- quick and easy commissioning (required mounting material with 2x screws, dowels and mounting plate included)
- automatic connection to the backend via preconfigured SIM card
- simple and unobtrusive design to protect against vandalism
- available in the future with an internal instead of the current external power supply
There are no significant limitations, except that, as with all ZENNER IoT gateways, configuration on other backend systems outside of the ZENNER Datahub is currently not possible. Therefore, there is currently no way to view the gateway together with other sensors in the personal ZENNER Datahub /client. The latter is basically only required for the installation of sensors whose data is to be received via the gateway (see also the “Installation & Setup” section below).
For whom and what the Gateway is suitable
The gateway is ideal for municipal utilities, public institutions, but also many other companies/organizations that want to quickly and easily start implementing their own LoRaWAN® use cases in the Internet of Things. On the other hand, the GatewayPLUS Indoor can also be used to cost-effectively expand or expand an already used ZENNER Connect network.
The gateway is suitable for the implementation of a wide range of applications such as multi-sector reading (heat cost allocators, water and heat meters, smoke detectors, etc.), submetering, monitoring of local network transformer stations or air quality measurement (e.g. CO2 level). The prerequisite for this is, of course, the corresponding devices/sensors that send their data via the gateway.
Construction & use of common IoT Infrastructure
Every GatewayPLUS Indoor automatically expands the LoRaWAN® network of ZENNER Connect GmbH. This means that, due to the technology, all LoRaWAN® devices in the reception area of your gateway are received in encrypted form and transmitted to ZENNER Connect as the network provider. Encryption and client separation in the ZENNER Datahub ensure that each end user only receives the data from their own devices. By purchasing a GatewayPLUS Indoor, you also create added value for the entire B.One Community, as this creates an ever-growing, jointly usable IoT infrastructure. You yourself benefit directly from the connectivity even beyond the reach of your own gateway – and together we are driving digitization forward in various areas. And so that you as a community member can see where there is already network coverage by other members’ gateways, you can optionally make the approximate position of your own gateway visible in the so-called Community Map.
GatewayPLUS Indoor with optional Visualization
As described in the overview article about the ZENNER IoT gateways, the GatewayPLUS Indoor is also available in the ZENNER Shop, with or without the ZENNER IoT PLUG&PLAY convenience option. The advantage of the latter: in addition to the always included LoRaWAN® network access, you also receive a 2-year license for the B.One Gallery visualization platform. With this you can easily visualize and evaluate the data from up to 50 IoT sensors.
Here is an example of the visualization of relative humidity and CO2 level in the B.One Gallery:
You can find more about the platform in our blog category “B.One Gallery” and on zenner.de.
Installation & Setup – easy & fast
Installing and setting up the GatewayPLUS Indoor is quick and easy, similar to the GatewayPLUS SMART. Regardless of whether you order the ZENNER IoT PLUG&PLAY convenience option or not, the pre-configured gateway is known to the ZENNER Connect LoRaWAN® network upon delivery due to the installation already carried out for you in the ZENNER Datahub (see above) and automatically establishes a network connection after switching on (even if, as explained above, you cannot yet see it in your personal Datahub account/client, which you will receive or have already received after ordering the gateway). If no separate power connection is required at the desired installation location, all you have to do is mount your device on the wall with the supplied screws and dowels and the mounting plate and plug it in. It can already receive the data from your sensors within range and forward it to a visualization platform such as the B.One Gallery. A full step-by-step guide to installing and assembling the GatewayPLUS Indoor can be found in the associated assembly instructions.
