EMS-ESP Gateway Case

thingiverse

This is a project for an EMS-ESP Gateway (EMS = Energy Management System by Buderus Heaters).\r\nI designed and built this gateway using my own PCB based on proddy's schematic and software [1] - thanks to proddy and Ingo Fischer, who made it possible in 2015 to connect to the EMS bus with the ethersex project!\r\n\r\nYou will need:\r\n* This case\r\n* My custom PCB (available on github [2])\r\n* 4 M3x30 screws\r\n* 4 M3 brass inserts 4x8mm\r\n* 4 2.2x8 plastic screws\r\n* One Node-MCU V2.0 ("Amica")\r\n* One DC-DC converter [3]\r\n* Additional electronic components (check the BOM-list on github [2])\r\n\r\n[1] https://github.com/proddy/EMS-ESP\r\n[2] https://github.com/LineF/EMS-ESP/tree/ems_project\r\n[3] https://www.aliexpress.com/item/32826540392.html?spm=a2g0s.9042311.0.0.27424c4dVhBdDI\r\n\r\nTwo of the bolts are glued at the back of the case, which holds it firmly against the wall when screws are pushed and turned.
