RS232 control for homebridge -- 2

Job ID: 31628578

Budget: $30 – $250 USD

I would like someone to write a plug-in for homebridge (https://homebridge.io/)
Allowing me to control my NAD amplifier via RS232 (https://nadelectronics.com/wp-content/uploads/2016/09/C-368-RS232-Codes.zip)

Im thinking this is done by using a TTL board for a dedicated raspberry on the local network.

Here is a plug-in template for homebridge (https://github.com/homebridge/homebridge-plugin-template)
