INTRODUCTION

1.1 Purpose

The Z-Ware Portal (see [1]) also functions as an IFTTT (If This Then That – see ifttt.com) Channel Server. This document is meant as an addendum to the Z-Ware Web User Guide to explain its IFTTT functionality.
To use the IFTTT Z-Ware Channel, the user needs:

• An IFTTT user account
• A Z-Ware Portal account
• A ZIPGW (Z -Wave over Internet Protocol Gateway) running on a Raspberry Pi3, connected to the Z-Ware Portal.

1.2 Audience and prerequisites
Public who are familiar with IFTTT.

Z-WARE PORTAL REGISTRATION

Z-Ware Portal is accessed at https://z-ware.sigmadesigns.com . It connects to the user’s home through the ZIPGW. The user will register their account through the ‘Register’ link at the bottom.

To create the Portal account, the user needs to select ‘Z/IP Gateway on Other Boards’ fill in the registration details.
First & last names are alphabets only and between 3 to 25 characters in length. Username is of the same length but can be alphanumeric, in addition supporting both ‘_’ (underscore) and ‘.’ (period) special characters. Password must be between 8 to 16 characters in length. The time zone setting allows ZWare to convert time information in accordance with the locality of the ZIPGW.
The ZIPGW platform’s Ethernet MAC address should be used in EUI-64 format (https://en.wikipedia.org/wiki/Organizationally_unique_identifier#64bit_Extended_Unique_Identifier_.28EUI-64.29) as the RAC (Remote Access Code) by the user. The Ethernet MAC address can be obtained as specified in Section 3.
On registration, an email is sent to the registered email address which contains an unregister link in case the user entered the wrong details & wishes to reregister. A link to download certificates, named ZIPR.key_1024.pem and ZIPR.x509_1024.pem, is also enclosed and these certificates will have to be downloaded to the platform as specified in Section 3.

ZIPGW CONFIGURATION

ZIPGW on the Raspberry Pi 3 (RPi3) platform needs to be configured to use the Z-Ware Portal. This requires ssh/scp access from the host machine to the target RPi3 machine.
3.1 Obtaining Ethernet MAC address of ZIPGW
Search the MAC address in ZIPGW log file at /var/log/zipgateway.log on RPi3.

less /var/log/zipgateway.log | grep “L2 HW addr”

Or the MAC address can be seen in the beginning of log file as marked below:

To convert the MAC in MAC-48 format to the RAC in EUI-64, the colons need to be changed to dashes, the letter capitalized and ‘FF-FF’ needs to be inserted in the middle. For eg:
00:1e:32:11:4c:92 -> 00-1E-32-FF-FF-11-4C-92

3.2 Downloading certificates to the Raspberry Pi3 platform
On the host machine, copy (scp) the certificates to RPi3:
$ scp ZIPR.key_1024.pem ZIPR.x509_1024.pem pi@:/tmp
Move the files on RPi3 to /usr/local/etc:

sudo mv /tmp/ZIPR.key_1024.pem /usr/local/etc/

sudo mv /tmp/ZIPR.x509_1024.pem /usr/local/etc/

Make sure that the configuration variables ZipPrivKey and ZipCert in ZIPGW configuration file /usr/local/etc/zipgateway.cfg, are mentioning the path respectively to those files as shown below.
ZipPrivKey=/usr/local/etc/ZIPR.key_1024.pem
ZipCert=/usr/local/etc/ZIPR.x509_1024.pem
Verify the configuration variables:

less /usr/local/etc/zipgateway.cfg | grep ZipPrivKey

less /usr/local/etc/zipgateway.cfg | grep ZipCert

3.3 Configuring for Portal
By default the image is set for the ZIPGW to connect to Z-Ware CE on the board. To modify it to connect to Z-Ware Portal, ensure that /usr/local/etc/zipgateway.cfg has the following lines:
ZipPortal=z-ware.sigmadesigns.com
ZipPortalPort=44123
Reboot once the change is made.

IFTTT

4.1 IFTTT Channel
The Z-Ware IFTTT channel can be found at https://ifttt.com/zware

Clicking ‘Z-Ware Triggers and actions’ reveals the different Triggers and Actions supported. Before these can be used in an IFTTT applet, the user needs to click ‘Connect’ to log in to the user’s existing ZWare Portal account.

4.2 IFTTT Applets
4.2.1 Lock your Z-Wave door and turn off your Z-Wave lights and thermostats, when you leave home
This applet works with Android Location service to detect your leaving an area and allows you to set multiple devices off.
4.2.2 Set your Z-Wave dimmer to match any Facebook hashtag
This applet works with your Facebook account to match a specified hashtag and set your dimmer as you specify.
4.2.3 Turn on your Z-Wave thermostat heating at sunset
This applet works with the Weather Underground service to detect sunset and turn your Z-Wave
Thermostat Mode to Heating.
4.2.4 Press a button to turn on your Z-Wave switch
This applet works with the IFTTT Button Widget service to turn on your Z-Wave switch.
4.2.5 Send Gmail when your Z-Wave sensor detects motion
This applet works with your Gmail account to notify you of your Z-Wave sensor detecting motion.
4.2.6 Send Gmail when your Z-Wave sensor detects water leak
This applet works with your Gmail account to notify you of your Z-Wave sensor detecting water leak.
4.3 IFTTT Actions
4.3.1 Turn on/off a switch
These 2 actions will turn on or off a Z-Wave binary switch you specify.
Action Fields: Which device?
4.3.2 Lock/Unlock a door
These 2 actions will lock or unlock a Z-Wave door lock you specify.
Action Fields: Which device?
4.3.3 Set a dimmer
This action will set a Z-Wave multilevel switch to a level you specify.
Action Fields: Which device? What level?
4.3.4 Set a thermostat to off/heating/cooling/auto mode
These 4 actions will set a Z-Wave thermostat to the specified mode if supported.
Action Fields: Which device
4.4 IFTTT Triggers
4.4.1 Binary Sensor condition detected / no longer detected
These 12 triggers fire when a Z-Wave sensor detects or no longer detects the specified binary condition.
Trigger Fields: Which sensor?
This covers the following sensor conditions:

1. Motion
2. Smoke
3. Carbon Dioxide
4. Carbon Monoxide
5. Door/Window Contact
6. Water

4.4.2 Multi-Level Sensor value drops below or rises above specifed threshold
These 6 triggers fire when a Z-Wave Multi-Level sensor detects a drop below or rises above a threshold.
Action Fields: Which sensor? Threshold Value & Unit
This covers the following sensor values:

1. Temperature
2. Humidity
3. Luminance

The user must select the correct unit currently used by the sensor for the trigger to work correctly.
4.5 IFTTT User Applets
To create your own Applets, click on “My Applets” in Figure 4: IFTTT Channel and follow the instructions as you proceed. This UI is solely controlled by IFTTT and is subject to change. The only part the ZWare channel controls are the parameters to its own actions, triggers, and applets.
