Intro

This is a simple guide on how to automate UK lights with a Shelly 1 by installing the shelly 1 relay into the ceiling pendant which has both permanent live, neutral and a switched live back from the wall switch.

These steps are from my own experience making my lighting "smart" but also user friendly (it works via a wall switch!). This simple guide will go through replacing an a normal ceiling pendant with one with room for a Shelly 1. If you have a ceiling light with a bigger base it's even easier.

Warning Electrical regulations must be followed by law. If you are not a competent person under the regulations do not attempt electrical work. https://www.diydoctor.org.uk/projects/electrical_safety.htm

Wiring Diagram

This diagram has been taken from here and modified to include the Shelly 1.

# STEP 1 - Build the binary

# use the golang image as build image
FROM golang

# copy the local package files to the container's workspace.
ADD . /go/src/github.com/dj95/homekit-api

# set the working directory to build the application

Kubernetes on Hypriot

These are instructions for standing up a Kubernetes cluster with Raspberry Pis with the current Hypriot (1.9.0), with K8S v1.10.5

Thanks to https://gist.github.com/alexellis/fdbc90de7691a1b9edb545c17da2d975 and https://gist.github.com/aaronkjones/d996f1a441bc80875fd4929866ca65ad for doing all the hard work!

Pre-reqs:

• This was done using a cluster of 5 RPi 3 B+
• All Pi's are connected via a local ethernet switch on a 10.0.0.0/24 LAN

How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

• HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

Z-Stick Serial API

The Z-Stick does bi-directional communication over a UART. The connection speed is 115200, '8N1'. There are "requests" and "responses". The client software can make requests to the Z-Stick, and it will send responses. But it seems the Z-Stick can make requests of the client software too. I have yet to figure out the requests the Z-Stick sends to the client software.

Ubiquiti USG Advanced Configuration

Overview

Integrated DNS Overview

When using a USG with Ubiquiti's Unifi Controller software (version 5.6 and earlier), the functionality of integrating the hostnames of clients (when they request a DHCP lease) into local DNS does not appear to work as you would find with Consumer grade routers. To work around this limitation, we can add static host mappings to a configuration file that will be provisioned to the USG when either a configuration change is made or we force provisioning to the USG itself.

Non-GUI Supported Dynamic DNS Providers

I've added in the necessary syntax for adding Cloudflare DDNS to the USG for VPN/Services setup courtesy of this post by britannic on the Ubiquiti Forums.
