A generic multi-purpose sketch built on top of the CoogleIOT platform to control an arbitrary number of switches via GPIO pins on an ESP8266 using MQTT.
Once you've downloaded the sketch, you'll need to add the CoogleIOT library to your project. You will also need to
configure the settings by editing the config.h file. An example of this file is shown below:
#ifndef COOGLESWITCH_H
#define COOGLESWITCH_H
#define NUM_SWITCHES 2
#define TOPIC_ID "hallway-power"
#define SWITCH_BASE_TOPIC ""
// List of pins, in order, that we will be switching on/off
static int switches[NUM_SWITCHES] = {
4, 5
};
#endif
NUM_SWITCHES The total number of switches being controlled
TOPIC_ID The MQTT topic ID being used (see below)
SWITCH_BASE_TOPIC The Base Topic (see below)
switches[NUM_SWITCHES] An array of pin numbers for your device, where the first pin is Switch #1, second Switch #2, etc.
The switches will be controlled via MQTT by publishing a 1 or a 0 to SWITCH_BASE_TOPIC/TOPIC_ID/switch/SWITCH NUMBER. Since by default
SWITCH_BASE_TOPIC is empty you can turn on/off the switches using the configuration described above by publishing a 1 or a 0 to:
/hallway-power/switch/1
The state of each switch can also be determined by subscribing to the same with an additional state appended:
/hallway-power/switch/1/state
