Alexa discovery

I am having some trouble with Alexa discovering OpenHab2 devices. Alexa discovers all my non-OpenHab2 devices just fine. I suspect that I’m missing something obvious.

I have added the Amazon Echo Control Binding through Paper UI (I don’t believe there is anything to configure).
I have connected Alexa and myopenhab in Alexa. myopenhab “My Applications” confirms that the link is authorized.
In the OpenHab Cloud Connector I have exposed the thing “RaspiLEDGreen”.
In my items files I have the following line:
Switch RaspiLEDGreen [ “Switchable” ] {gpio=“pin:4 initialValue:low”}
The url “https://home.myopenhab.org/rest/items/RaspiLEDGreen” gives this result:
{“link”:“https://home.myopenhab.org:443/rest/items/RaspiLEDGreen",“state”:“ON”,“editable”:false,“type”:“Switch”,“name”:“RaspiLEDGreen”,“tags”:[“Switchable”],"groupNames”:[]}

The state reported in myopenhab is correct, so I’m confident that the information is getting to myopenhab.

Any thoughts? Thanks.

Add a label to the item. The label is the name you need for alexa.

You need a label after raspiledgreen. Labels are in quotes.

Thanks. I modified the line and added a label. The challenge is then that Alexa won’t allow me to query the state of RaspiLEDGreen.

Maybe I should explain - RaspiLEDGreen is just an LED off my RPi driven by rules. I know that I can’t connect Contact items to Alexa so I figured that I’d connect the LED. But I don’t want to control the LED state with Alexa, just query the status.

As far as i know the binding does not support asking the state of an item.

That is my thinking at this point as well. I can issue commands to OpenHab2 via Alexa (close my garage doors for example). Even using IFTTT through Alexa I can’t query OpenHab2.
