* Clarify configuration a bit It wasn't clear to me if the config part applied to only RaspBee or everything, so I tried to clarify it with titles. I also added a bit of text to show where the correct value can be found (though I additionally had to google what the different values are to decide which one to use) * Update README.md
deCONZ
Add-on to allow Home Assistant to control a ZigBee network with Conbee or RaspBee hardware by Dresden Elektronik.
First Steps
RaspBee
If using RaspBee, you may need to edit config.txt on the root of your SD card for your RaspBee to be recognized and assigned a device name. Add folling information to config.txt:
enable_uart=1
dtoverlay=pi3-miniuart-bt
Config
Before starting the add-on for the first time after installing, in the add-on config you must specify the device name that has been assigned to your RaspBee/Conbee as the device. Replace null and specify the device name in quotes (e.g. "/dev/ttyUSB0", "/dev/ttyAMA0", or "/dev/ttyACM0").
If you're using Hass.io you may find the correct value for this on the Hass.io -> System -> Host system -> Hardware page.
The other config options have sensible defaults that should not need to be changed unless you are debugging.
Use a 2.5A power supply for your Raspberry Pi 3! Strange behaviour with this Add-on may otherwise result.
Adding ZigBee Devices
After installing and starting this addon in Hass.io, access the deCONZ WebUI ("Phoscon") with WebUI button.
Configuring the Home Assistant deCONZ Component
If discovery: is enabled in configuration.yaml, navigate to the Configuration - Integrations page after starting this Add-on to configure the deCONZ component.
If discovery: is not enabled, follow these instructions to configure the deCONZ component: https://home-assistant.io/components/deconz/.
Migrating to this Add-on
To migrate deCONZ to Hass.io and this Add-on (or before uninstalling/reinstalling this Add-on), backup your deCONZ config via the Phoscon WebUI, then restore that config after installing/reinstalling. You must perform these steps or your Light and Group names and other data will be lost! (However, your ZigBee devices will remain paired to your Conbee or RaspBee hardware.)
