RPi 3, RaZberry2 and Domoticz: Anyone got it to work?

[Kent]

Hi,

I have tried for a few days to get this to work. Some time I have been able to get Domoticz to find the razberry, (on /dev/ttyUSB20 after creating a symlink) but then it is impossible to add devices. And the controller is unknown.

After running rpi-update, the AMA0 serial port is gone from Domoticz, and the ttyUSB20 does not work.

Can anyone point me in the right direction?

Thanks!

You have to disable Bluetooth on the PI

[Kent]

Thanks for your answer Yustmenl. Unfortunately, I have tried that with no success. After many hours of reading forum threads and testing new things, I started to note what I did this time. This is what I did tonight:

Writing the file 2016-09-23-raspbian-jessie-lite.img to a 16GB micro-SD card using win32diskimager.

Insert the card, power up the pi and log in with SSH from my windows machine using Putty.

First, check the version:

Code: Select all

pi@raspberrypi:~ $ uname -a
Linux raspberrypi 4.4.21-v7+ #911 SMP Thu Sep 15 14:22:38 BST 2016 armv7l GNU/Linux

Then, using

Code: Select all

sudo raspi-config

Extending the partition to the whole card.
Change user password.
Set boot mode to console (not GUI)
Install sv_SE.UTF8 locale, but keep the GB locale default.
Select timezone Stockholm.
Memory split: 16M GPU memory.
Inactivates the serial console.
After that, raspi-config reboots the pi.

Then, with info from this post:
http://www.domoticz.com/forum/viewtopic ... 615#p78615

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install rpi-update
sudo rpi-update
sudo reboot

Code: Select all

pi@raspberrypi:~ $ uname -a
Linux raspberrypi 4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016 armv7l GNU/Linux

Code: Select all

sudo nano /boot/config.txt

add to the end of the file:
dtoverlay=pi3-disable-bt

Code: Select all

sudo systemctl disable hciuart
sudo reboot

Installing Domoticz using this info: https://www.domoticz.com/wiki/Installin ... spberry_PI

Code: Select all

mkdir ~/domoticz
cd ~/domoticz
wget http://releases.domoticz.com/releases/release/domoticz_linux_armv7l.tgz
tar xvfz domoticz_linux_armv7l.tgz
rm domoticz_linux_armv7l.tgz
sudo cp domoticz.sh /etc/init.d
sudo chmod +x /etc/init.d/domoticz.sh
sudo update-rc.d domoticz.sh defaults
sudo service domoticz.sh start

I am then able to log in to the Domoticz web interface. I try to add a new hardware, and selects OpenZWave USB in the list. But there is nothing in the "Serial port" box, as seen in the attached screenshot.

Have I done something wrong so far? I have read that the symlink should not be necessary for newer versions of Domoticz.

I bought the Razberry2 unit from m.nu, it is a newer version with better antenna. https://www.m.nu/razberry2-gen5-p-2830.html

[Kent]

I finally found the problem! For some reason, there was a line "enable_uart=0" in the file "/boot/config.txt". I changed that zero to a one, rebooted, and then there was possible to select /dev/ttyAMA0 as port in Dometicz! See attached screenshot.

Also, this time, it was possible to include devices!

Time to have some fun!

I hope this post can help someone else that got similar problems...

But tell me you must also disabled Bluetooth before ?

[Kent]

But tell me you must also disabled Bluetooth before ?

Yes, that's what I did in my third post in this thread, by adding "dtoverlay=pi3-disable-bt" in the file /boot/config.txt

[piokuc]

Ahhh ok...i am thinkingthat for RaZberry 2 we not must disable bluetooth.

And for what is this command:

Code: Select all

sudo systemctl disable hciuart

?

And on RaZberry 2 range is better ? All other parameters are probably the same. Is It changed Razberry on Razberry 2?

Hi! Did you run before razberry 1 and rpi2? What is your experience in terms of performance and signal compared to previuos setup? Thanks

Hi,

I just installed domoticz with the following setup:

* Razberry2
* Raspberry Pi 3
* Raspbian Jessie, 2017-01-11

There are a couple of things to keep in mind for the Razberry2 to work properly, especially with the later jessie releases:

* The serial port has to be turned ON
* Console on the serial port has to be turned OFF
* Bluetooth has to be disabled
* hciuart.service can optionally be disable (to get rid of an error message during boot)

So, the minor issue is that when you use "raspi-config" to turn off the serial console, it does not only turn off the console output on the serial port. It also turns off the serial port, which is not really what we want. That is why most people get a bit confused and fiddle around until they figure out that the "enable_uart=0" entry in /boot/configure.txt should be "enable_uart=1", and never think of why it happened to be that way.

The "console output" to serial is configured in /boot/cmdline.txt with the entry "console=serial0,115200", which we need to get rid of, but still make sure that there is no "enable_uart=0" in /boot/config.txt.

Unless you really want to, there is no need to redistribute the GPU RAM mapping.

So, a working setup (as of 2017-01-20) is:

* Create an SD card with 2017-01-11-raspbian-jessie.img
* Before you unmount it from your PC, change the following files on the SD card:

/boot/cmdline.txt

Code: Select all

cat /boot/cmdline.txt 
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

/boot/configure.txt

Code: Select all

enable_uart=1
dtoverlay=pi3-disable-bt

* Boot the raspberry pi
* Disable the hciuart service

Code: Select all

sudo systemctl stop hciuart    
sudo systemctl disable hciuart

* Ensure you have a /dev/ttyAMA0 file

Code: Select all

ls -la /dev/ttyAMA0 
crw-rw---- 1 root dialout 204, 64 Jan 20 08:19 /dev/ttyAMA0

* Install domoticz as described above by kent

Code: Select all

mkdir ~/domoticz
cd ~/domoticz
wget http://releases.domoticz.com/releases/release/domoticz_linux_armv7l.tgz
tar xvfz domoticz_linux_armv7l.tgz
rm domoticz_linux_armv7l.tgz
sudo cp domoticz.sh /etc/init.d
sudo chmod +x /etc/init.d/domoticz.sh
sudo update-rc.d domoticz.sh defaults
sudo service domoticz.sh start

* Go to "Setup"->"Hardware"
* Add a OpenZWave USB device with the serial port: /dev/ttyAMA0

Done.

Hi !

For my raspberry3 with razberry2 I simply:

Installed raspbian jessie lite to SD, made wlan static, and then :

Code: Select all

pi@raspberrypi:~ wget -q -O - razberry.z-wave.me/install | sudo bash 

Code: Select all

pi@raspberrypi:~ $ sudo raspi-config

Enabled ssh, localisations, expanded space

Code: Select all

pi@raspberrypi:~ sudo curl -L install.domoticz.com | bash

Thats all i did. Works fine. At any point i did not disable bluetooth, so i presume its disabled by default ?

Part of the razberry.zwave.me/install script disables bluetooth.

Code: Select all

# Disable bluetooth Raspberry Pi 3
RPI_BOARD_REVISION=`grep Revision /proc/cpuinfo | cut -d: -f2 | tr -d " "`
if [[ $RPI_BOARD_REVISION ==  "a02082" || $RPI_BOARD_REVISION == "a22082" ]]
then
	echo "Raspberry Pi 3 Detected. Disabling Bluetooth"
	systemctl disable hciuart
	# Add "dtoverlay=pi3-miniuart-bt" to /boot/config.txt if needed
	if [[ ! `grep "dtoverlay=pi3-miniuart-bt" /boot/config.txt` ]]
	then
		echo "Adding 'dtoverlay=pi3-miniuart-bt' to /boot/config.txt"
		echo "dtoverlay=pi3-miniuart-bt" >> /boot/config.txt

And i forgot to mention, u need to disable z-way after all this to use domoticz OZW...
