WARNING: This is one of my first 3D Designs. it is dependent on the PSU size which can vary, you might need somepost-printing adjustments to assemble the levels depending on your printer's accuracy and the top cover should be a little bit higher to avoid pressing the Razberry button.
I use Domoticz for my home automation with the following hardware :
- Raspberry Pi 3 (more current, but I can take it anywhere to include new devices)
, Z-Wave.me Razberry daughter card
- MySensors Ethernet Gateway
- Raspberry UPS on LiPo (not for power failure, but I can take it anywhere to include new devices without halt-unplug-plug-boot cycle)
. Generic 5V/4A power supply (standard adapters are not powerful enough)
- SDCard protected, but still accessible without unscrewing
I wanted to be able to unplug the server to bring it with me, close to the device to include without halting, unpluging, plugging again, booting and initializing. I chose a Raspberry 3 for the Wifi chipset and to avoid the need for an ethernet plug. I chose to have an UPS included in the server.
I wanted to have a design isolating the high voltage from the low voltage parts, in separate cells, with a switch for the high voltage input and a switch for the UPS.
I wanted passive cooling, I added heat sinks to the raspberry and a lot of holes to the case. The hole position is chosen to leverage the natural convection air flow, and to keep the high voltage (heat generator) isolated from the low voltage case.
I wanted something as compact as possible, I chose to keep the MySensors gateway connected with ethernet, I can place it at the best radio position and communicate with the server by Ethernet+Wifi. Regarding the RFX433trx, I did not want to unmount it or to split the USB power from the USB data, so, I choose to keep it apart as an external add-on.
I hate to remove supports from my printings... I wanted a supportless design.
Basically, the server includes the core (Power supply, UPS, Raspberry and ZWave shield, everthing else is optional (RFX and MySensors)
