SmartThings Archives

So it has been brought to my attention by my lovely wife that PSE&G has a Market place. If you are not from NJ you might be asking what is PSEG? PSE&G or Public Service Energy Group is the local power supply company the services NJ and Long Island NY. Now you might be asking what are they selling on this market place. Well as it turns out, they are selling Smart Home Devices! Particularly Smart thermostats from all of the big players like Google Nest, Ecobee, and Honeywell. They even have some pretty good deals on there for people who may not have the capital to invest in one of the big names.

My Wife found an Emerson Sensi, which is a WiFi smart thermostat that will integrate with your Google Home, Amazon Alexa, and Smartthings hub for $0. All you have to do is pay tax and shipping which comes out to be $11.

Needless to say she ordered it, and I will be doing a review of it when I get it in.

Here is a link to the PSEG Market Place, check it out and see if there is something you would be interested in. If you need help, just drop me a line.

I hope you find this post helpful and if so please share it with your friend.

I have been away for a while, but in my absence I have been playing with a Home Automation System called Home Assistant. You can find out more about it here on their website: https://home-assistant.io/

One of my Father’s Day Gifts from my Wife and Kids was a SmarThing Hub with a Arrival sensor. Now Home Assistant has literally hundreds of pre-built integrations however SmartThings is not one of them. To make it work with Home Assistant you will have to use a protocol called MQTT which is very versatile and can be used to create your own Automations. (Find out more about it here.)

Now my Home Assistant instance is running on a Rasberry Pi 3 (also a Father’s Day Gift) however it also runs on a Raspberry Pi 2. I am also running HASSbain which is a Raspian image created by Home Assistant. As for MQTT there are a few products out there that you can use, I prefer Mosquitto as there seems to be more guides out there on how to configure and manage it.

Start off by checking for and installing updates for Raspian:

sudo apt-get update

sudo apt-get upgrade

this could take a while depending on your setup.

Next you will need to setup the smarthings-mqtt-bridge via npm
sudo apt-get install npm

sudo npm install -g smartthings-mqtt-bridge

Then you will need to setup pm2 to run the processes
sudo npm install pm2 -g

Once installed you will need to create and edit smartthings-mqtt-bridge config
sudo cp /usr/local/lib/node_modules/smartthings-mqtt-bridge/_config.yml ~/config.yml

sudo nano ~/config.yml
Here is what the mqtt-bridge-configuration ~/config.yml file should look like if all is configured correctly.
mqtt:
# Specify your MQTT Broker’s hostname or IP address here
host: mqtt://localhost
# Preface for the topics $PREFACE/$DEVICE_NAME/$PROPERTY
preface: smartthings

# Suffix for the state topics $PREFACE/$DEVICE_NAME/$PROPERTY/$STATE_SUFFIX
# state_suffix: state
# Suffix for the command topics $PREFACE/$DEVICE_NAME/$PROPERTY/$COMMAND_SUFFIX
# command_suffix: cmd

# Other optional settings from https://www.npmjs.com/package/mqtt#mqttclientstreambuilder-options
username: pi
password: mqttpass

# Port number to listen on
port: 8080

Now that all of the local configurations have been completed you need to configure the SmartThings Device handler, Device, and SmartApp using steps outlined in https://github.com/stjohnjohnson/smartthings-mqtt-bridge150

Device Settings
IP: raspberry pi IP
MAC: Raspberry pi MAC
Port: 8080

Next you will need to add mqtt to HomeAssistant config configuration.yaml
mqtt:
broker: localhost
port: 1883
client_id: home-assistant-1
username: pi
password: mqttpass

Now you will need to add your devices to their own file, or configuration.yaml
Since I am using mine for presence detection mine looks something like this

device_tracker:
– platform: mqtt
name: “MQTT Presense Detection”
devices:
Friendly Name: smartthings/device name/presence
Friendly Name1: smartthings/device name/presence

Now you will need to start the bridge

sudo ln -s “$(which nodejs)” /usr/local/bin/node
pm2 restart smartthings-mqtt-bridge

restart Home Assistant
sudo systemctl restart home-assistant.service

That should do it. You may want to sudo reboot

In the future I may do more of these as I have learned at lot from it, including beginning to dabble with Docker.
