Domoticz Pi setup

Expand file-system to allow access to the entire SD card

sudo raspi-config

Enable SSH and logging

sudo nano /etc/init.d/domoticz.sh

--

Disable power management for WLAN

sudo nano /etc/modprobe.d/8192cu.conf

# Disable power management
options 8192cu rtw_power_mgnt=0

If using a vanilla Rasbian install:

Disable the system trying to use ttyAMA0 (used by the Razberry GPIO)

Remove the following from /boot/cmdline.txt:

console=serial0,115200

Temporarily stop by using:

sudo systemctl stop serial-getty@ttyAMA0.service
sudo systemctl disable serial-getty@ttyAMA0.service

Though this will be re-enabled at boot unless the console is removed from cmdline.txt
