I need you to develop a simple controller to: 1. Read the modbus from the water and electricity meters and send them to our server through MQTT Protocol. 2. To be interfaced with C.T. an flowmeter (PWM) to calculate the water and power consumption also. The recommended controller is esp8266. No time wasters please and changing the price after discussion is completely unacceptable.

Hi! I have already developed board with esp8266 to control greenhouses (with sensors, relays, uart, usb and even reserve power from battery). I only need to redesign board for your application. I indicated 21 days for the project, so it takes time to purchase sample components and fabricate a sample board.
