It works great after-hours.Īdditionally, we have external speakers with a separate RPi in the restroom. Thanks to this, everyone connected to our WiFi can stream music wirelessly to a specific audio section. Two of the Raspberry Pis are connected to the amplifier and run DLNA and AirPlay servers. We divided them in multiple sections and connected to a broadcasting amplifier. The owner of the building gave us them for free as our office space used be shopping area before we took all the walls down. We ended up having high quality speakers all around the office mounted in the ceiling. We can now use the Web Application to control if we display the projector on each TV independently. Instead of rewiring the whole system, we made a simple hack: a bunch of HDMI switches and splitters connected together created the ability to change the TV source from Raspberry Pis. keynotes during events available to the public) we knew we needed an image from the projector to be shown on the TVs. Chrome Debugging Protocol is used control it from the web (that is the main Raspberry Pi). This was achieved by simply running Chrome in kiosk mode on each device. They are all independent showing mostly funny memes or websites with meaningful information. There are five additional Raspberry Pis connected to separate TVs. Signals are gathered in the device described above. This function is achieved by a regular movement sensor mounted in each room. The main unit also runs a web server with a Web Application that allows to control all of the features. There is one relay for each light group which makes over 30 pieces to handle the entire Monterail office. Relay is like a wall switch but instead of turning it on and off by hand you put voltage onto it. The second device is a relay driver board.The first one we called the “distribution board”: distribute power and provide connectors that connects all peripherals: the RPi itself, movement sensors, door lock, etc.To accomplish this we had to create two kinds of custom devices: There is one master Raspberry Pi which controls all of the low-level hardware. We debated about reliability as we couldn’t find a project based on RaspberryPi that big. “Let’s do something new, something that we haven’t seen on the Internet before.”Īfter some consideration we put our bet on Raspberry Pi. Most automation systems we found were built based on PLCs – due to their reliability and strict manufacturing restrictions. Technical decisions and reliability risks Work with JavaScript experts who will push hard to understand your business and meet certain deadlines. Of course, there were some small complications during whole venture, but everything ultimately ended up as we wanted. The entire hardware side of the smart office had taken place during the construction work done by the renovation crew. ability to control everything via a web application (desktop, mobile, phone and panels mounted on the walls).Īfter that, the automation system project was done and the whole office concept was ready to be implemented in real life. ![]()
