Smart Lock

Internet controlled lock example using NodeMCU and MQTT protocol.

Demo control panel is hosted on Firebase at https://smart-lock-hca.firebaseapp.com

 

MQTT Broker

We're using CloudMQTT, but feel free to choose your provider.
Then update auth details in nodemcu_lock/nodemcu_lock.ino and web-panel/src/script.js

 

NodeMCU

1. Install NodeMCU board in Arduino IDE.

2. Open nodemcu_lock/nodemcu_lock.ino in Arduino IDE.

3. Install the following libraries.
   Sketch -> Include library -> Manage libraries.

   • WiFiManager
   • PubSubClient
