Sound familiar?
Three situations we hear again and again — and that cosy-one solves.
„As soon as the technician leaves, no one dares to touch the system. For every small change we have to call."
With cosy-one the verger operates everything himself — bells, light, sound, heating — through a panel as simple as a light switch.
„Every guest struggles with the room technology. My staff spend half their day on support instead of with the guests."
With cosy-one one press of a button starts the room correctly — light, sound, projector, climate — no training and no IT ticket.
„Our rooms keep running even when no one is there. And no one has an overview of what is happening where."
With cosy-one rooms respond to actual occupancy instead of a timer — and you see everything in one dashboard, from anywhere.
/cosy-one is this simple
One entry. And everything runs.
Plan
Enter an appointment or programme — once, in the calendar.
One button
The room starts correctly: light, sound, climate, bells and displays.
Overview
See and change everything — from anywhere, in one interface.
Made for your everyday
The church year runs on its own.
On Good Friday the bells stay silent, the lighting remains restrained and the church is warm in time — without anyone having to think about it in the morning. Once set up, cosy-one follows the entire church year on its own, and if something should ever be different, a single button is enough.
The room is ready before the guest is.
Seminar booked — light, sound, projector and climate are right at the right time. Your staff look after the guests, not the technology.
Rooms that think along.
Sensors detect occupancy and air quality, heating and ventilation respond by themselves. You save energy and see in the dashboard what runs where.
/The ecosystem
Three building blocks that work as one.
cosy-one is not a single device but a carefully matched ecosystem for parishes, hotels and businesses. The online platform, the hardware on site and the modules work seamlessly together — so the technology finally works for the people who operate it every day.
cosy-connect
The online platform
With cosy-connect you open your entire installation in an ordinary browser — from anywhere, without an app and without a VPN. You see every site in real time, assign clear roles for administration, technicians and operators, and adjust programmes without being on location.
That way nobody has to drive out for every little thing, and you can step in calmly and securely the moment an installation needs your attention.

The hardware on site
The cosy-hub is the compact DIN rail server that runs all licensed modules right where you are. It speaks GPIO, Modbus and REST and reliably controls relays, sensors and subsystems from a single device.
Your installation keeps running even if the internet goes down, and your data stays in the building — you depend on no foreign cloud.

The modules
Each module adds one clearly defined capability — from bell control and room scheduling to sensors and data analysis. You activate exactly what you really need and extend at any time, without buying new hardware.
This means you never pay for features you don't use, and your system still grows with you as new requirements arise.
cosy-module in detail →/Modules — only what you need
Every capability a benefit.
License only what is actually needed — and extend at any time.
Plan the event — the technology sets itself up. One calendar entry is enough: light, sound and climate switch correctly on their own.
License on requestYour bells ring at the right moment and fall silent when the church year calls for it — fully automatically, without anyone having to remember. And whenever something should be different, a single click lets you ring or pause them.
License on requestThe room senses what it needs — and responds by itself. Heating and ventilation follow real occupancy instead of a timer.
License on requestYour Shelly devices — finally controlled in one place. Sockets, light and blinds included, without an extra app or foreign cloud.
License on requestUnderstand what your buildings really need. Clear insights instead of a graveyard of numbers — and a warning before things go off track.
License on requestUp-to-date displays throughout the building — centrally managed. Door sign, info screen or schedule, maintained once, current everywhere, power-saving E-Ink.
In developmentEvery image on the right screen — at the push of a button. Camera, presentation or lyrics land exactly where they belong — no plugging cables.
