I have used the following code in Raspi 4. When I run the code it displays field1 and field2 on the screen. However my channel is not receiving any data. Writing Payload = field1=6.6&field2=17.2 to host: mqtt3.thingspeak.com clientID= xxxxxxxxxxxxxxxxxxxx User xxxxxxxxx PWD xxxxxxxxxxxxxxxx import paho.mqtt.publish as publish import psutil import string # The ThingSpeak Channel ID. # Replace <YOUR-CHANNEL-ID> with your channel ID. channel_ID = "xxxxxxxx" # The hostname of the ThingSpeak MQTT broker. mqtt_host = "mqtt3.thingspeak.com" # Your MQTT credentials for the device mqtt_client_ID = "xxxxxxxxxxxxxxxx" mqtt_username = "xxxxxxxxxxxxx" mqtt_password = "xxxxxxxxxxxxx" t_transport = "websockets" t_port = 80 # Create the topic string. topic = "channels/" + channel_ID + "/publish" while (True): # get the system performance data over 20 seconds. cpu_percent = psutil.cpu_percent(interval=20) ram_percent = psutil.virtual_memory().percent # build the payload string. payload = "field1=" + str(cpu_percent) + "&field2=" + str(ram_percent) # attempt to publish this data to the topic. try: print ("Writing Payload = ", payload," to host: ", mqtt_host, " clientID= ", mqtt_client_ID, " User ", mqtt_username, " PWD ", mqtt_password) publish.single(topic, payload, hostname=mqtt_host, transport=t_transport, port=t_port, client_id=mqtt_client_ID, auth={'username':mqtt_username,'password':mqtt_password}) except (keyboardInterrupt): break except Exception as e: print (e)
