How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.

To use the most modern version of Postgres software we need to add postgresql repository. Edit /etc/apt/sources.list or create /etc/apt/sources.list.d/pgdg.list and add there a line: deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main Then import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Install a new version of PostgreSQL server.

Once the Debian upgrade finished, I used dpkg-query -l postgresql* to check which versions of postgres I have installed.

TP-Link Kasa Smart Plug - get energy consumption statistics as a CSV file

Background

The TP Link Kasa smart switches log energy consumption data over time, however the app is very limited and won't let you get out data, graph it or see historical usage. This script extracts and saves to a CSV file.

The python-kasa library is used to communicate with the Kasa switch.

Requirements

• Python must be installed
• You must be on the same wifi network as the Kasa switch
