I need you to develop a firmware to read data devices trough 3 raspberry pi working as gateways and develop advanced dashboard in ubidots, check attached document.
I need three main things:
1) Develop the required firmware to read data from devices connected to 3 Raspberry Pi Modbus shield which is fact the gateway
2) Open communication between platform and gateways
3) build dashboard and graphics as specied in the document Client Platform Requirements
It's quite important to fulfill the timeline in 2 - 3 weeks.
