What does Smartnest do?
Smartnest is a home automation platform that lets you connect Arduino, ESP, and other microcontroller boards to the internet. Once connected, you can control your devices from a web browser, an iOS or Android app, or through voice assistants like Google Assistant, Alexa, and Siri. The platform also integrates with SmartThings, Tasmota, ESPurna, Homebridge, and Home Assistant, so you can fit it into your existing smart home setup.
The system works by providing a cloud backend that your devices talk to via MQTT or HTTP. You get a dashboard to monitor and control each device, and you can set up routines or triggers. What makes Smartnest stand out is its wide range of integrations — you can link it to almost any major smart home ecosystem. It also offers a full API, so developers can build custom integrations or automate workflows. The platform is free to use for basic features, with a donation model to support development.
Smartnest is best for hobbyists and makers who want to build their own smart home devices without buying expensive proprietary hardware. If you have a spare Arduino or ESP8266 lying around, you can turn it into a smart switch, a temperature sensor, or a doorbell that talks to your Google Home. It's also useful for anyone who wants to experiment with IoT and voice control without committing to a commercial ecosystem.
