Project description
Hardware: EMS interface circuit (See Documentation or PBC-files folder). Arduino Mega 2560 Rev3 + Arduino Ethernet Shield with Wiznet w5100 Raspberry Pi, PC or other device running Domoticz The EMS bus interface can be converted to TTL level by means of a simple circuit. The TTL-converted signal can then be connected to one of the the Arduino UARTs. See the Documentation folder. The sketches here use the Arduino Mega 2560 and the Wiznet 5100 ethernet shield. You can also use another Arduino like the Uno but that one only has one hardware serial port. Serial1 is used for the EMS module…
