    Hello, I need a controller based on ESP8266 to do the following: 1- Read the values from LDR,PIR,ON/OFF Switches,Temp. Sensor & Modbus Port then Send them to the webserver via MQTT protocol. 2. receive instructions from the server via MQTT Protocol to switch ON/OFF or to generate a PWM. 3. ESP8266 should first authenticate the webserver then send and receive data as per the following format (Esp no., pin no., action (ON/OFF or PWM), starting time). please read well the requirements and quote only if you are committed and ready to work. The budget is max. 40USD for such scope of work. Regards,

    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.

    I have many esp8266 that works as WEB-servers, they have a unique port and IP address. I need to create another MAIN Gateway that could manage all my existing ESP8266 web-server modules without the need of opening many ports for each of my WIFI modules. Some other developer suggested star topology, and other MQTT. But I do not want to change my HTML web-server built-in modules because they work perfect. The only need is to manage many like 50pcs or 100pcs by using a Gateway connected to home router.
