It all started when...we wanted to monitor temperatures in our meeting rooms. The thermostat was the most reviled device. What was cold for one colleague would be too hot for another. So what exactly was the temperature in the room? How can I see all the temperatures of all the meeting rooms and of the other rooms from a central location. Not necessarily sitting in another part of the office.
Thus was born this idea that we could connect sensors through a gateway into a local or cloud server. And run either MQTT or HTTP or a simple Web-socket connection to monitor temperature and other data critical to the workplace.
