Marian Marinov, the Chief System Architect at SiteGround, has extensive experience in system administration since 1996 and is involved in teaching network security and Linux courses. The document details the requirements and specifications for a building automation system, including remote control of lights and a compact design. Solutions included using specific components like MCP23017, ULN2803, and optocouplers, with a management controller for testing being a Raspberry Pi.

- 4. - control the lights remotely(via IP) - control large number of switches/lights(a minimum of 32 per floor) - get the current status of the lamps What were ourWhat were our requirements?requirements?
- 5. - compact design, so it will reduce the size of the power distribution boxes at each floor - ability to audit and modify the SW - DIN mountable - easily replaceable parts What were ourWhat were our requirements?requirements?

- 20. Initial planInitial plan -not enough I/O pins on the Pi -huge relays -electricity from the relays can damage the Pi - no state collected
- 22. The resultThe result - 2x MCP23017 - 2x ULN2803 - optocouplers

- 35. DIN MountDIN Mount - We choose the dimensions of the PCB, based on the available DIN mounting options - We also considered the space we had in the power distribution boxes
- 37. ControllerController - We choose i2c so we can connect multiple boards to a single controller Achieving of up to 64 inputs and 64 outputs
- 38. ControllerController - Management controller used for tests was Raspberry Pi - Production controllers will most likely be OLinuXino
