IoT door bell


This is the default Mongoose OS app + modified init.js. It's for ringing an IoT bell over MQTT.

For the bell, you can make one with a cheap reception bell and a 5V solenoid. Make sure you use a relay and a relay drive circuit and don't connect the solenoid directly to the GPIO pin.

Change relayPin, topic, or bellNumber if necessary.
