This was my very first time building a web application. I had absolutely no prior web development experience — only a background in C programming. With the help of ChatGPT, I was able to turn an idea into a real product, implementing nearly everything I imagined.

Big thanks to GPT — it helped me bypass technical barriers and bring my idea to life!

💡 What is WattBattle?

WattBattle is a lightweight, open-source web app that:

• Retrieves real-time solar data from the IAMMETER Cloud API
• Allows users to enter their device SN and token (or use demo mode)
• Calculates daily values for solar generation, energy consumption, export, and self-use rate
• Ranks users based on their performance across selected metrics
• Resets the rankings daily to keep things fresh and competitive

It’s a fun, interactive way to “brag about your watts” with friends or fellow solar enthusiasts — inspired by a real Amazon review of the IAMMETER WEM3050T!

If you're a maker, hobbyist, or developer using IAMMETER energy meters, I encourage you to build your own creative tools, dashboards, or games!

Here are a few ideas to get started:

• Fork WattBattle and build upon it
• Create a custom energy dashboard for local use
• Design visualizations for your smart home setup
• Share your project with the community!

IAMMETER even runs a reward points program for community contributions.

Thanks for reading — I hope WattBattle sparks some inspiration. Feel free to try it, fork it, or break it 😄. And if you build something with IAMMETER, let me know!
