RaZberry2 Setup, Tips, Hints and Tweaks

 

Follow the setup here to ensure your Raspberry Pi is setup correctly to integrate with Domoticz

Step 1: Raspberry Pi Prep

  • sudo nano /boot/config.txt
    • add to end of the file: dtoverlay=pi3-disable-bt
    • removing: ‘console=serial0,115200’ from cmdline.txt
  • sudo nano /boot/cmdline.txt
  • sudo systemctl disable hciuart
  • sudo stty -F /dev/ttyAMA0 9600
  • sudo reboot

Domoticz installation

Domoticz integration

The RaZberry is connected to the GPIO pins on the Raspberry Pi and installs as a device on the “ttyAMA0” port. Domoticz can only access “ttyUSBX” ports so we’ll be adding a rule that creates a link on boot to a port that Domoticz can use

  • sudo nano -w /etc/udev/rules.d/09-tty.rules
  • KERNEL==”ttyAMA0″, SYSLINK+=”ttyUSB20″
  • sudo reboot

Open http://IP:8080

  • Click “Setup” on the Domoticz menu, followed by “Hardware
  • Click “Enabled” is ticked, then type a descriptive name in the “Name” field
  • From the dropdown “Type” list, select “OpenZWave USB
  • From the dropdown “Serial Port” list, select “/dev/ttyUSB20
  • Click the “Add” button

Your RaZberry device should now be shown in the list – click on the “Setup” button next to it

Issue 1:

An error can occur during the firmware/software upgrade installation producing the following message when connecting to Razberry to http://IP:8084

“Webif is switched off. You can switch it on from Z-Way UI or box shell” is displayed

Enter the following at the CLI and try again:

  • sudo echo 900 > /opt/z-way-server/automation/storage/8084AccessTimeout-6b497208061ec7faae003cdd7f9a035e.json

Domoticz Alexa integration

You can setup Amazon echo to voice trigger any scene/switch/activity in domoticz using HA-bridge (e.g. “Alexa, turn on living room lights” ). I have been using this setup with an amazon echo outside the target market for the echo (In India) and it works beautifully well. The HA-bridge emulates Philips hue devices that is supported natively by the echo

Pre-requisites

  • An Amazon Echo device
  • A spare RPi/processing capacity on your domoticz box/ any other linux box
  • HA-bridge running on the above mentioned box

I use a spare Gen 2 Rpi B that I had lying unused The rest of the guide assumes that the HA-bridge is running on a separate box
