Compiling open-zwave-control-panel on a Raspberry Pi 3¶
I've recently started diving into home automation stuff, and of course immediately ran into issues. I purchased a z-wave water sensor and planned to use Home Assistant to monitor the sensor and send me alerts (via pushover) if it detects water. While getting HA installed was quick and easy, the trouble began when I tried to actually read from the sensor. I could see in the OZW_Log.txt log file that the system was receiving data, but the HA log had no event information.
After a bunch of searching, I came across a post talking about using open-zwave-control-panel (ozwcp) to diagnose and configure z-wave devices. Awesome! Sadly, the documentation for this project is lacking, and it took a bit of trial and error to figure out the right steps to get ozwcp build, let alone run. Eventually I figured it out, reconfigured my sensor and everything worked. So to save others the frustration of trying to build ozwcp, I've got a quick and simple tutorial for you!
There's a docker image that's only slightly out of date, I suggest trying that first before going to the effort of compiling ozwcp. If you don't have docker installed, follow one of the many tutorials out there, then run this command (where /dev/ttyUSB0 is your zwave controller):
docker run -p 8008:8008 --device /dev/ttyUSB0 openzwave/openzwave-control-panel &>/dev/null &
And now back to our regularly scheduled programming.
Please note, these instructions have only been tested on Raspbian 8 (jessie) on a Raspberry Pi 3. Your milage may vary! All commands are run as root, because I'm lazy.
First, install some (probably) important libraries:
apt-get update apt-get install libgnutls28-dev libgnutlsxx28
Download, build and install libmicrohttpd
cd wget ftp://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.19.tar.gz tar zxvf libmicrohttpd-0.9.19.tar.gz mv libmicrohttpd-0.9.19 libmicrohttpd cd libmicrohttpd ./configure make make install
Download and build the open-zwave library
cd git clone https://github.com/OpenZWave/open-zwave.git cd open-zwave make
cd git clone https://github.com/OpenZWave/open-zwave-control-panel.git cd open-zwave-control-panel
Open the Makefile and find the following line:
OPENZWAVE := ../ LIBMICROHTTPD := -lmicrohttpd
Change it to:
OPENZWAVE := ../open-zwave LIBMICROHTTPD := /usr/local/lib/libmicrohttpd.a
make ln -sd ../open-zwave/config
And finally, run it!
./ozwcp -p 8888
Now you can open
http://your\_system:8888 in a browser to start using the open-zwave-control-panel!
