newbie needs help starting binding [message #1746565]

I am new to Eclipse SmartHome and have very little experience with Eclipse IDE.

I would like to develop a binding for a heat pump system using the serial binding as a baseline.

I followed the Setting Up a Development Environment from
https://www.eclipse.org/smarthome/documentation/development/ide.html
but am rather at a loss as to what to do next.

The last step indicates:

Your workspace should now fully compile and you can start the runtime by launching the "SmartHome Runtime" launch configuration:

which it appears to be doing in the Eclipse IDE, but now what? I was hoping there was a tutorial that would walk me through looking at, or developing a binding.

The Binding "Tutorial" at

https://www.eclipse.org/smarthome/documentation/development/bindings/how-to.html

explains some sample code and explains theory of the binding, but doesn't talk about the logistics of what I actually do to get started.

For instance,

1) What do I do in the Eclipse IDE if I want to look at the Yahoo Weather Binding (or the Serial Binding for that matter)

2) How do I build the binding and where are the built binding files so I can copy it into a running ESH?

3) How can I debug a binding in the Eclipse IDE?

Hi Nathan,

Welcome and sorry for the late reply!

The Eclipse SmartHome IDE setup is mainly required if you want to work on the source code of ESH itself. If you "only" want to implement bindings, the better choice for you might be the openHAB 2 IDE (see http://docs.openhab.org/developers/development/ide.html), which is less complex.

Specifically in your case, you do not have any other option, since the transport.io.serial binding (which you will require) does not exist in ESH due to licensing reasons, but only in openHAB. Also for other more general development issues, you might find some help in the openHAB developer guide at http://docs.openhab.org/developers/development/bindings.html.

Hope this helps you to get started.

Best regards,
Kai

Thanks Kai!

In the Eclipse IDE Package Explorer, I have found

OpenHab 1 Add Ons -> org.openhab.binding.serial, but I don't see transport.io.serial binding in OpenHab 1 Add Ons or OpenHab 2 Add Ons. In fact, I don't see anything else related to serial. Did I not install something, or am I looking in the wrong place?

It's not necessarily in the workspace, it is in your target platform. Just check that you can select it there in your launch configuration. Have a look at a few other openhab2 bindings that use serial connection, which should compile nicely as well (check https://github.com/openhab/openhab2-addons/search?utf8=%E2%9C%93&q=gnu.io&type=Code).

Thanks Kai, Abin!

I have been trying to emulate the Introduction to binding development video, but when I get to the running of the OpenHab Paper UI, the binding does not show up.

In trying to diagnose, I notice that the binding does not show up in the pom.xml after the ./create_openhab_binding_skeleton.sh <binding name> command.

Any ideas why the binding does not appear?

Hi Nathan,

In your debug configuration, under the Plugin Tab, have you checked whether your binding is selected?

Regards,
Abin

Abin,

Yes, I did do that. I am suspecting it may stem from something earlier since it didn't show up in the pom.xml.

What is the mechanism that controls which bindings show up in the Paper UI->Configuration->Bindings page?

Currently, I am only seeing the following in the Paper UI->Configuration->Bindings page:

1) hue Binding
2) NTP Binding
3) YahooWeather Binding

SOLUTION: I figured out why my new binding was not showing up when I ran Eclipse in debug mode. I had previously installed openhab at /opt/openhab and that configuration was apparently causing havoc when I ran the Eclipse openhab in debug mode.

I zipped the /opt/openhab folder and removed /opt/openhab and now my new binding shows up!
