Rehau Neasmart 2.0 Gateway Add-On
This Add-On simulates a Modbus slave through serial or ModbusTCP in order to iteract with a Rehau Neasmart 2.0 system, it exposes a set of RESTful apis to control the systems through an Homeassistant custom component.
This Add-On requires a Serial to USB adapter or a ModbusRTU Slave to ModbusTCP adapter. (ModbusRTU over TCP or ModbusRTU over UDP can be supported but are not at this time) Something like an ESP or an Arduino works but many cheap off-the-shelf devices work too (eg. this one I'm using now with PoE and DIN rail mounting)
