Computherm Q7 RF thermostat button pusher

Last crawled date: 4 years, 2 months ago

If you set the temperature to HOLD, then simply can unlock it by pressing the SET button in the thermostat, This mechanisam, helps you to push button from everywere, via MQTT protocol, by Adafruit.

Control your wireless termostat via Adafruit MQTT.
Only need one esp 8266, one dht 11 sensor, and one SG90 servo
What Need to change in the source :
define WIFI_SSID "YOUR WIFI SSID"
define WIFI_PASS "YOUR WIFI PASS"
define MQTT_NAME "YOUR MQTT USER"
define MQTT_PASS "YOUR MQTT PASS"
Sorce to Arduino :
include
include "Adafruit_MQTT.h"
include "Adafruit_MQTT_Client.h"
include
include
Servo servo;
int angle = 0; // servo position in degrees
int servoPin = 14;
include "DHT.h"
define DHTPIN 2
define DHTTYPE DHT11
define WIFI_SSID "YOUR WIFI SSID"
define WIFI_PASS "YOUR WIFI PASS"
define MQTT_SERV "io.adafruit.com"
define MQTT_PORT 1883
define MQTT_NAME "YOUR MQTT USER"
define MQTT_PASS "YOUR MQTT PASS"
DHT dht(DHTPIN, DHTTYPE);
//Set up MQTT and WiFi clients
WiFiClient client;

//Set up the feed you're subscribing to
Adafruit_MQTT_Subscribe onoff = Adafruit_MQTT_Subscribe(&mqtt, MQTT_NAME "/feeds/onoff");
Adafruit_MQTT_Publish temperature = Adafruit_MQTT_Publish(&mqtt, MQTT_NAME "/feeds/temperature");
Adafruit_MQTT_Publish humidity = Adafruit_MQTT_Publish(&mqtt, MQTT_NAME "/feeds/humidity");

//Subscribe to the onoff feed
mqtt.subscribe(&onoff);

//Read from our subscription queue until we run out, or
//wait up to 5 seconds for subscription to update
Adafruit_MQTT_Subscribe subscription;
while ((subscription = mqtt.readSubscription(5000)))

//If we're in here, a subscription updated...
if (subscription == &onoff)

}
else
{

// ping the server to keep the mqtt connection alive
if (!mqtt.ping())
{
mqtt.disconnect();
}
int humidity_data = (int)dht.readHumidity();
int temperature_data = (int)dht.readTemperature();
temperature.publish(temperature_data);
humidity.publish(humidity_data);
delay(100);
