Play Bluno is an app that provides extreme ease for DIYers,Arduino enthusiasts,and home automation zealots to do demonsrations and tests with Bluno controller board via BLE(Blutooth Low Energy) communication. Specially designed for the Arduino-based BLE hardwares, users can easily learn to control and interact with a variety of functions with their phone. For example, displaying real-time temperature and humidity data on the phone,switching lights on/off or stimulating a full-color L_E_D light. It offers you a new way to learn and play with electronic devices via BLE communication. Based on the Arduino hardware platform, it's quite easy for you to build a network and test your own system based on BLE. Play Bluno is first of its kind to solve the problem of communication between hardwares via BLE and is designed to change this situation. The user interface of Play Bluno is quite clear and straightforward. The 7 areas are designed in correspondence with 7 key functions of the Accessory board,including an L_E_D LCD, a buzzer, a temperature and humidity sensor, a five-way button, a relay module, a full-color L_E_D and a knob. Once opened, the user can see directly the different key functions displayed in one screen. After establishing BLE connection, the user will be able to tweek and controll these functions on the Accessory board simoutaneously on the phone. The Play Bluno and the related hardware design are completely based on the Open Source Hardware concepts. There is documentation and support for this modules. The designs, schematics and codes will be Open Source. Play Bluno will be also a good start for you in tackling hardware installations such as wearables. So for developers now that you have the software and the hardware, it's time to start creating your own things with Play Bluno, and make it whatever you like. Functions and Advantages DIY and Prototyping Educational Switchs for controlling the electronic devices and other functions Based on Arduino opensource hardware platform. Recommended to be used with BLUno board and Accessory board.

BluSi opens all your doors with your phone. Front door, garage, cellar, shared room or shop: you open, you give access and you choose who can come in, with no keys and no spares to cut. OPEN - Tap Open at the door, or let it open as you arrive if you wish. The button sits at the bottom of the screen, near the menu. - Favorites: your favourite BluSi Box first, in the order you choose, with directions to each one. - Hold to open: for a garage or a shutter, the door stays open as long as you press. - Even without a network, when your access allows it. - In "My preferences", set automatic opening, opening time and video calls for each door. "Calibrate" fits the automatic opening distance to your phone, with readings taken on the spot. GIVE ACCESS - Add one or more people at once, by QR code or by e-mail. An invitation sent to an address is reserved for that address. - Create a code in advance for a tradesperson or a delivery, with a start and an end. One code can open several doors, and the BluSi Pad shows each door it opens. Each code shows the location and address of the door, and the site entries show when it is used. - Remove an access whenever you want. A lost phone is removed from the app. VIDEO INTERCOM A visitor calls you from the door or from the BluSi Pad, and the call shows the name of the BluSi Pad. You see the visitor and open during the call. The call rings on the chosen phones and the first to answer handles it. With "Reach me", choose your contact hours for each space, or take a break. SELF-SERVICE In a self-service space, take a free access in the app. It is yours with your own code until you release it. FOR BUILDINGS AND PROPERTY MANAGERS Your accesses are organised by site, location, space and BluSi Box, and the map shows each location with its address. Each space has its seats, one per person. Site administrators set up the spaces, the seats, the BluSi Box, the intercom and the BluSi Pad, and every BluSi Box has its own "Settings" page. Entrances, garages, cellars and shared rooms are managed from one account, and the online dashboard lets you prepare everything from a computer. SECURE AND SWISS Data hosted in Switzerland. No lost keyring to replace. A BluSi Box installed on the door is required. More at blusi.ch. Questions? support@blusi.ch
