I have two raspberry pis that i'd like to wire up using AWS IoT
AWS Iot Notes
AWS Setup Notes
http://docs.aws.amazon.com/iot/latest/developerguide/policy-actions.html
aws iot list-policy-principals --policy-name mypolicy aws iot list-principal-policies --principal ?? aws iot list-principal-things --principal ?? aws iot list-thing-principals --thing-name mypi1
principal means certificate.
THINGS <-> PRINCIPAL ( cert ) <-> POLICY
best guid so far:
https://www.hackster.io/mariocannistra/python-and-paho-for-mqtt-with-aws-iot-921e41
this is the policy that AWS gives the rile that Iot WIll use to port to ES

Script service setup
from: http://www.diegoacuna.me/how-to-run-a-script-as-a-service-in-raspberry-pi-raspbian-jessie/
/lib/systemd/system/awsiotpub_temp.service
[Unit] Description=IoT AWS Sensor Publisher After=multi-user.target [Service] Type=simple ExecStart=/usr/bin/python /home/pi/python-paho-mqtt-for-aws-iot/awsiotpub_temp.py Restart=on-abort [Install] WantedBy=multi-user.target
enable:
sudo chmod 644 /lib/systemd/system/hello.service chmod +x /home/pi/hello_world.py sudo systemctl daemon-reload sudo systemctl enable hello.service sudo systemctl start hello.service
on creating rules with variable substitution
http://docs.aws.amazon.com/iot/latest/developerguide/iot-substitution-templates.html
for example if you want to post data from device X to an elasticsearch index with id X
you should generate a new uuid id for each reading:
"id": "${newuuid()}"
AWS ElasticSearch setup
curl 'https://search-myiotcatcher-eq4tipuq24ltctdtgz5hydwvb4.us-east-1.es.amazonaws.com/_cat/indices?v'
Guides
- https://dzone.com/refcardz/getting-started-with-mqtt
- What is mqtt?
- https://www.hackster.io/mariocannistra/python-and-paho-for-mqtt-with-aws-iot-921e41
- I like this guide because it gives an example subscriber and an example publisher.
