  • Tvilight’s new IoT outdoor light controllers connect via open, reliable and proven international telecom standard (NB-IoT and LTE Cat-M1) used by billions of devices today
  • IoT controllers are available in both Zhaga (book 18) and NEMA (7-pin ANSI C136.41) variants
  • Controllers come with in-built 10 years fixed price data connectivity delivering best-in-class value

Amsterdam, the Netherlands – TVILIGHT, Europe’s leading smart street lighting solution provider, extends its portfolio of wireless smart street light controllers (SLC) / outdoor light controllers (OLC) by unveiling the OpenSky IoT devices. The OpenSky IoT street light controllers are built on the 3GPP’s next-generation NB-IoT and Cat-M1 global telecom standard, which offer long range, deep coverage, high availability, secured, and managed LPWAN (low power wide area network).

Open, Secure, Trusted

Traditional connected street lighting systems, that rely on Sigfox, LoRa, UNB, Wi-Sun and other proprietary non-standard communication, face several setbacks. For one, they need local proprietary gateway(s) to communicate with a CMS. Secondly, these private networks (for example, LoRa) require active management and maintenance of the communication infrastructure, including regular security updates and network patches. This results in cost, hassle and additional responsibility on the city council. Furthermore, long-term availability of such proprietary network is never guaranteed.

Open cellular networks help overcome these limitations while offering excellent reliability and security. “Our next-generation OpenSky IoT smart street light controllers use standardized cellular networks, namely EGPRS, EDGE, LTE Cat M1 and LTE Cat NB2 (in simple terms, 2G, 4G and NB-IoT). Thanks to this, OpenSky IoT controllers automatically select the best available local telecom network to connect directly with the CityManager central management system (CMS). This is similar to how a mobile phone and a smart watch work.” explains Chintan Shah, the CEO and CTO at Tvilight.

Mobile cellular networks are used by billions of devices today, offering guaranteed quality of service, highest security levels and a future-proof capability. Furthermore, this network infrastructure is fully managed by the local telecom operators at no additional cost or responsibility on the city councils.


Since OpenSky IoT controllers connect directly with the CMS and have an in-built GPS, it also eliminates the need for device commissioning. Installation contractors can simply install these plug-and-play SLC on compatible LED luminaires, without any special tooling or training. OpenSky SLC auto-commissions in a CMS, ready to receive switching or dimming commands and send vital luminaire health information to the lighting operator.

In-built 10-years data connectivity

Tvilight’s OpenSky IoT controllers offer excellent value to municipalities. “They come with in-built GPS, ambient light sensor, tilt sensor, and 10-years hassle free data connectivity. Our IoT SLC offer versatile dimming control, motion sensor support, advance luminaire health monitoring, D4i support, and OTA updates, to name a few. Additionally, we bring OpenSky IoT in both NEMA and Zhaga variants, ensuring that it is compatible with all modern LED street lights. It’s a perfect Smart City street lighting solution that is quick and easy to deploy citywide,” adds Heide Jeuken, CCO/ COO at Tvilight. “Furthermore, city councils greatly benefit from using the same CityManager CMS to manage both – IoT as well as the popular Tvilight RF mesh devices e.g. CitySense.

OpenSky IoT controllers will be available worldwide from Tvilight and its business Partners starting from 15 November 2020.
