Hi
i have a raspberry and i installed a DHT22
i receive values normally but the device keep connecting/disconnecting all the time…
can someone help?
because of this problem i cannot control any other GPIO from the panel!!..
i run the default code :
import paho.mqtt.client as mqtt
import time
import sys
import Adafruit_DHT
time.sleep(30) #Sleep to allow wireless to connect before starting MQTT
username = ""
password = ""
clientid = ""
mqttc = mqtt.Client(client_id=clientid)
mqttc.username_pw_set(username, password=password)
mqttc.connect("mqtt.mydevices.com", port=1883, keepalive=60)
mqttc.loop_start()
topic_dht22_temp = "v1/" + username + "/things/" + clientid + "/data/3"
topic_dht22_humidity = "v1/" + username + "/things/" + clientid + "/data/4"
while True:
try:
humidity22, temp22 = Adafruit_DHT.read_retry(22, 04)
if temp22 is not None:
temp22 = "temp,c=" + str(temp22)
mqttc.publish(topic_dht22_temp, payload=temp22, retain=True)
if humidity22 is not None:
humidity22 = "rel_hum,p=" + str(humidity22)
mqttc.publish(topic_dht22_humidity, payload=humidity22, retain=True)
time.sleep(10)
except (EOFError, SystemExit, KeyboardInterrupt):
mqttc.disconnect()
sys.exit()
