Blynk Climate API

Overview

The Blynk Board is a powerful device for home automation, and this project allows you to build a powerful API for accessing the current status of the climate around your Blynk board, while also alerting you when values exceed thresholds. Have a certain corner in your home that has a narrow set of operating conditions. Place a Blynk board there and set it up with this server. You can easily get push notifications through IFTTT or another similar service.

This project can be demoed and the public API can be accessed for no charge athttps://blynkweather.herokuapp.com/
