Consultancy needed for starting a new IOT cloud WebApp: Aquarium / Grow controler

FREELANCERS ONLY! NO TEAMS! I'm starting a new IOT project for aquarium / grow control cloud webapp. And before i start developing the webapp i would like to consult and brainstorm with a more experienced freelancer on ways i can accomplish this new webapp, You must have some experienced with: - Java - Arduino & Raspberry PI - MQTT / ECLIPSE etc.. - framework for Dashboarding (php) Short brief: The webapp would have some similarity to [login to view URL] in a way user may add a new dashboard and connect multiple arduinos nodes to that dashboard, however it has its own built in functions / sensors that once activated, and path to sensors function is set by user it will activate the function and its configurations on the relevant arduino sensor node (or provide a sketch to user for copy/paste). The functions are hard-coded, and user only have to add his preferred configuration: For example when to turn on/off the light, and path to the relay. Example: User create his first dashboard (maybe he/she has 2 aquariums) > User upload the default generated sketch to connect the arduino sensor node to dashboard > In dashboard settings user activate and configure dashboard functions, such as: 1A . When to turn light on? Option 1: between ______(ex. 08:00) to _____(ex. 20:00) Option 2: Sunset to sunrise 3. sunrise to sunset (built in function) 1B. Where is the relay responsible for the light? ________ (Arduino sensor node "1", digital PIN "3") 2A. would you like to monitor water temperature? if yes, what are is the minimum temperature ____(18) and max temperature ____(28) 2B. Where is the sensor (DS18B20) responsible for water temperature located at? ______ (Arduino sensor node "2", Digital Pin "34") (the dashboard configuration page have similar questions as the above) > Once user save the settings it will automatically upload or generate a code to upload the necessary sensor module & settings to the arduino node > the new sensor or relay data will be available on dashboard (like it will show when light is on or off) If you are interested, i can quickly prepare a flowchart with some more info about what i would like to accomplish, PM me for info. This project/task will be considered completed when the freelancer deliver the following: Theoretical level - Research / search / Think for an easy solution to accomplish the webapp (for example a combination of MQTT, API, XX Framework etc..) Practical level - Prepare a basic example (based on research) to show how this would work out i reality Once this task is completed, the chosen freelancer may provide an offer for developing parts of the project (we can discuss who make what part). HAPPY BIDDING, PM if you have any questions.
