OpenRemoteHelpers under version 2.0.0

[pz1]

It seems that the OpenRemoteHelpers module is not working anymore under version 2.0.-rc8. I do get error message Invalid ZAutomation request
That can be tested with the WEBbrowser. For example I took command

Code: Select all

http://raspberry:8083/ZAutomation/OpenRemote/TemperatureLevel/13/3

Which is supposed to read the temperature level of the fist sensor of the Fibaro FGBS001. This did work well in 1.7.2.
As a matter of fact none of OpenRemote calls does return a value. I guess the module needs adaptation for the new 2.0.0. Or can I find somewhere an update? I just use wgat comes with the RC.

Yes, url access is changed in 2.0.

But you may fix it quite simple. Just add the following line in the end of OpenRemoteHelpers:

Code: Select all

allowExternalAccess("OpenRemote");

And drop /ZAutomation part from the url, so it would be http://ip:8083/OpenRemote/…

I have added the allowExternalAccess at the end of the index.js of module OpenRemoteHelpers:

Code: Select all

OpenRemoteHelpers.prototype.stop = function () {
    OpenRemoteHelpers.super_.prototype.stop.call(this);

    OpenRemote = null;
};

allowExternalAccess("OpenRemote");

Restarted Z-Way server

Command http://raspberry:8083/OpenRemote/TemperatureLevel/15/3

reports now 404 Not Found

Has it even loaded? Do you have any errors in log?
I've tried to do the same, and it kinda works

Just not sure about response format, as strings like "on" and "off" are returned with quotes (default JSON serialization)

Just got this solved: I did a complete reboot of the Pi

Apparantly restart Z-Way-server was not enough.
I have it working for Switches and Universal sensors. I am now confident to change all urls to my 10 StellaZ devices.

CPU usage seems the same as under 1.7, not yet the 1-2% predicted for release 2.x

PS: Shouldn't you guys add this line:

Code: Select all

allowExternalAccess("OpenRemote");

To the OpenRemoteHelpers JS file?

I'll make a prelimenary write-up of this transition from 1.x to 2.x under Recipes

[pofs]

Sure, we'll add it.

About CPU usage: 1-2% was measured on my laptop (against 3-4% on 1.7), not on RPi. Sure it would be a bit higher on RPi because of different architecture and computing power.
We don't have influence on resources used by v8 engine on a specific platform. Just watch mem and CPU usage isn't growing too much

Can confirm that StellaZ main functions work fine now with OpenRemoteHelpers. There are a few minor functions e.g. device location/name that were in the old RaZOR module, which are (not yet) in the OpenRemoteHelpers.

You can add allowExternalAccess in OpenRemote module if you want to shorten URLs from /ZAutomation/OpenRemote to /OpenRemote.

@pofs: why allowExternalAccess is global and not in ws?

[pz1]

On my own machine I have extended the index.js op OpenRemoteHelpers a bit. For my OR-GUI I do use devicename and location as they are stored in my StellaZ devices.

Just before case "metrics" I added:

Code: Select all

            case "DeviceName":
                return zway.devices[N].instances[I].NodeNaming.data.nodename.value;

            case "DeviceLocation":
  			    return zway.devices[N].instances[I].NodeNaming.data.location.value;

By the way, what is the "metrics" suposed to do for me?

Code: Select all

http://raspberry:8083/OpenRemote/metrics/21
Uncaught TypeError: Cannot read property 'get' of undefined

[PoltoS]

metrics are to fetch directly metrics from HA. Out /ZAutomation/api/v1/devices/StellaZ1 returns JSON object, while OpenRemote can not parse it. This 'metrics' is made ti fetch data from it.
