Read out Z-Wave device on razberry

[sc0rpi0n16]

Dear community,

I am completely new to z-wave and razberry. I hope this question is not redundant, but I didn't found anything on the web concerning the following:

I have a raspberry pi 3 with the razberry modul and as a first z-wave device a cyrus multisensor.
Everything works fine and I can work with the Web UI.

My question is now, is there a possibility to read out the sensors of the z-wave device via command line of the raspberry pi? That I can use the information of the z-wave devices in my own scripts?

Thanks for the suggestions and answers in advance
Cheers

Hi,

I'm not expert. I'm currently doing the setup of my crontab in my Raspberry pi.

Here is a french website : http://www.magdiblog.fr/domotique/contr ... -razberry/

At the end there is some examples of script like :

wget -o ./z-way.api -O ./z-way.api http://127.0.0.1:8083/ZWaveAPI/Run/devi ... %28$val%29

This particular command line doesn't work for me. I opened a post yesterday to understand why this command line doesn't work when the same url works in a web browser.

I'm still looking for a solution.

Let me know if you find a solution.

You're my booster. I found the solution in this forum : https://forum.z-wave.me/viewtopic.php?f=3419&t=22778

To do this from the command line you need to authenticate first and save a session cookie...

wget -q --header "Accept: application/json" --header "Content-Type: application/json" --post-data '{"form":true,"login":"admin","password":"admin","keepme":false,"default_ui":1}' http://127.0.0.1:8083/ZAutomation/api/v1/login --keep-session-cookie --save-cookie /tmp/zway-cookie.txt -O - 1>&2 >/dev/null

Then you use that session cookie for all subsequent requests with --load-cookies.

wget --load-cookies /tmp/zway-cookie.txt "http://127.0.0.1:8083/ZWaveAPI/Run/devi ... ].Set(255)" - O - 1>&2 >/dev/null

I hope it helps.

Hi gazier20,

Thank you for your answer, that helped a lot.
I didn't quite managed it to get it working with the "wget" command but on this page (http://razberry.z-wave.me/index.php?id=13) I found the following which works for me:

Get a token with the following command:

Code: Select all

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '{"form": true, "login": "admin", "password": "admin", "keepme": false, "default_ui": 1}' 192.168.0.62:8083/ZAutomation/api/v1/login -c cookie.txt

Then for example one can extract the value of a temperature sensor (or any other sensor) with:

Code: Select all

curl -g http://192.168.178.88:8083/ZWaveAPI/Run/devices[4].instances[0].commandClasses[49].data[1].val.value -b cookie.txt

"ZWaveAPI" can also be exchanges with "ZWave.zway". The option "-g" in the curl command assurs that square brackets can be used in the link.
To also Set the values of different devices one can use the following (example for a command class SwitchBinary):

Code: Select all

curl -g "192.168.178.88:8083/ZWaveAPI/Run/devices[6].instances[0].commandClasses[37].Set(1)" -b cookie.txt

The syntax of the available API commands can be found here: http://razberry.z-wave.me/docs/zwayDev.pdf

Maybe this is helpful for some people.

Greetings!
