$30-250 USD

Paid on delivery
Hello, I need a controller based on ESP32 or 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- There are some manual switched to turn ON/OFF some devices manually in case the server connection is down, and those switches should be interfaces to the relays to control them either manually or from the server. 3 - It should read Modbus and send the data to the server. 4 - it should work as a universal IR remote control,and the controller should learn any remote control code and send it to the server to be stored then we can control any device from the web-server instead of using the IR remote control via IR LED. 5 - the server will send the instructions to the controller to be executed as it is without any processing in the controller. i.e. (PinA.1,ON,3 hours). The cost estimation for such scope of work is 75 USD and the delivery time is 5 days. Finally, Please no time wasters and changing the price after submition is not acceptable for the above mentioned scope of work (no random quotes please). Best Regards
