Shared Counter is the simple and effective tool for counting visitors to events, local businesses, religious functions and much more, even with multiple entrances. To begin, create a new counter, optionally specifying the capacity. You can then share the counter with other devices, for example to monitor multiple entrances at the same time, via a simple link or QR code. You will always have under control the total count of all devices, synchronized in real time. The service was created in particular for monitoring access to the churches, but is now freely available. If you are in charge of a church you can access the "Reserved area for churches", to benefit from usage statistics and other useful services on the DinDonDan Web Services. Shared Counter is an open source project offered and maintained by the DinDonDan App association.

About

TWIL

Features
Read full description

TWIL is an innovative wireless lighting management technology that allows configuration and control of installations through smart devices and PCs. A lighting system with TWIL technology can include high efficiency luminaires and automatic brightness controls based on the intended use of the enlightened environment, lighting to be provided in the area of the visual eld and the occupation and/or availability of natural light in a given environment. The TWIL system makes use of sensors that have a dual function, namely the detection of brightness and motion. The sensors interact with the fixtures to intelligently light an environment, saving energy and maintaining a constant level of lighting where needed; they can be installed at elevated heights of up to 11m, and are therefore compatible with industrial and commercial applications (high bay applications). With the App, TWIL allows you to manage, monitor and control many operating parameters of the fixtures, including the consumption of both the single unit and the entire system and to make clear accumulated energy savings, thanks to the potential use of the sensors or scheduling of lighting scenarios. TWIL technology enters the world of the new industrial revolution that moves forward on the internet, or industry 4.0. Production machines and systems communicate with each other and speak with the outside. TWIL LED technology is naturally integrated into this trend.
