The agent can be installed by navigating to the root directory of the agent code and running:
sudo python3 setup.py install
I wanted to do this, but
I do not know where that directory is or the name of it.
I got agent 2.0 installed

But I have lost the other type of connection, where I had the motion detector.
Now it looks like only 2.0 connection is working, but the motion detector is not finish in “bring your own”. So maybe I just got to wait some week until this is readdy?
you are trying to add motion sensor on raspberry pi agent 2.0 and a button on BYOT on same raspberry pi?
Yes, that is correct.
-------- Opprinnelig melding --------
so that when there is motion sensed it clicks a photo?
Yes, that is the plan, but now the motion sensor is not working with 2.0
-------- Opprinnelig melding --------
i have another approach for this. in your BYOT code add a code for motion sensor.
Thank you for your help but I am more than 60 years old, and do not know how to do that,or what to write.
I have the motion sensor on GPIO18, so I ftied this code for the callback function# The callback for when a message is received from Cayenne.
def on_message(message):
print("message received: " + str(message))
if (message.channel == 4) and (message.value == “1”):
print(“button is pressed”)
camera.start_preview()
sleep(5)
camera.capture(‘/home/pi/Desktop/image.jpg’)
camera.stop_preview()
if (message.channel == 18) and (message.value == “1”):
print(“motion”)
But there was no reaction.
I tested with a voltmeter, and the motion sensor changed the voltage from 0 til 3,2v on GPIO18, so it is working.
Maybe a high voltage is not the same as “1”?
try this code first and see if you get pir sensor reading:
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.IN) #PIR
while True:
if GPIO.input(pirPin):
print("Motion Detected...")
time.sleep(5) #to avoid multiple detection
time.sleep(0.1)
Yes, it is working. Had to change pirPin till 18. I guess this should have been declared, but yes it is working, so I could make the motion detaction and taking the picture without using Cayenne part, but I want to be notified when that happed. Most likly someone is in my boat then.
#!/usr/bin/env python
#import cayenne.client
import time
from picamera import PiCamera
from time import sleep
camera = PiCamera()
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.IN) #PIR
while True:
if GPIO.input(18):
print(“Motion Detected…”)
# time.sleep(5) #to avoid multiple detection
camera.start_preview()
sleep(5)
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()
time.sleep(0.1)
this is where the awesome cayenne comes into picture. add a two state widget. when a motion is detected the state becomes 1 and then you set a sms notification to let you know that someone is at your boat.
Yes, that will be my next challenge.
I looked at the send example and see this part of the code:
while True:
client.loop()
if (time.time() > timestamp + 10):
client.celsiusWrite(1, i)
client.luxWrite(2, i*10)
client.hectoPascalWrite(3, i+800)
timestamp = time.time()
i = i+1
I guess client.xxxxx(channel, value)
so I need to find a xxxxx that fits motion.
have a look at this Data types for Cayenne MQTT API
Thank you so much.
I have never been in a forum where someone has given me so much help so fast for free.
Thank again.

You’re welcome, sir.
more than happy to help you complete the awesome project with cayenne.

I feel like a child needing a helping hand for every step on the way.
Now I wanted to communicate the motion back to Cayenne so it could trigger an sms message to me.
I have the sms trigger attached to motion in Channel 2.
Here is part of the code:
# If there is an error processing the message return an error string, otherwise$
client = cayenne.client.CayenneMQTTClient()
client.on_message = on_message
client.begin(MQTT_USERNAME, MQTT_PASSWORD, MQTT_CLIENT_ID)
# For a secure connection use port 8883 when calling client.begin:
# client.begin(MQTT_USERNAME, MQTT_PASSWORD, MQTT_CLIENT_ID, port=8883)
i=0
timestamp = 0
while True:
client.loop()
if GPIO.input(18):
print("Motion Detected...")
client.virtualWrite(2,1,"Motion","d")
time.sleep(5) #to avoid multiple detection
camera.start_preview()
time.sleep(5)
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()
time.sleep(12) #wait so Cayenne web will show motion
else:
client.virtualWrite(2,0,"Motion","d")
time.sleep(0.1)
There is no reaction in the dashboard when there is motion,
so the sms trigger is not activated.
change this:
and
to
client.virtualWrite(2,1,"digital_sensor","d")
and
client.virtualWrite(2,0,"digital_sensor","d")
Try this:
motion = false
motioncounter = 0
while True:
client.loop()
if motion:
motioncounter += 1
if (not motion) or (motioncounter > 50):
if motioncounter > 50:
motioncounter = 0
if GPIO.input(18):
print("Motion Detected...")
client.virtualWrite(2,1,"digital_sensor","d")
camera.start_preview()
#time.sleep(5) ####If you really do need a delay here make it less than 1 second
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()
motion = true
motioncounter = 0
else:
client.virtualWrite(2,0,"digital_sensor","d")
motion = false
time.sleep(0.1)
The issue I see is that you are sleeping too long. client.loop() needs to be called at a minimum every 2 seconds or you will get disconnects
