Raspberry Pi Sensor App Development

I need a self-contained application developed for a Raspberry Pi that will receive temperature and humidity sensor inputs and control relays as outputs. I have the graphics ready; I just need someone to code it.

Requirements:
- Display sensor data as both graphs and real-time numerical values.
- Control relays based on the app inputs.

Ideal Skills and Experience:
- Proficiency in Raspberry Pi development
- Experience with sensor integration
- Strong coding skills, particularly in Python or relevant languages
- Ability to create user-friendly interfaces
