Item naming questions?

Setup, Configuration and Use Beginners
1

I had been using openhab2 betas last year. Anyway, figured I’d start fresh with OH2 release. Trying to have a go without doing much configuration by files; trying to use PaperUI.

I have a wemo lightswitch. It is detected in PaperUI, and I can turn it on and off.

I’ve been trying to write a rule that will turn the light on at sunset.

I eventually came up with the following, which works. But to get the switch name, I ended up going through the initialisation logs to find the name - how is one supposed to find the name or give it an alias to use in scripts?

rule "Turn On Lights After Sunset"
when
		Channel	'astro:sun:local:set#event' triggered START 
then
		
		wemo_lightswitch_Lightswitch_1_0_221609K13013B1_state.sendCommand( ON );
end

You could temporarily (edit:) disable Simple Mode in OH2 for Item Linking (in Paper UI -> Configuration -> System) and check the Items from the Paper UI sub-menu.

Thanks for your help.

Unfortunately, Simple Mode is already enabled.

“check the Items from the Paper UI sub-menu”

What Paper UI sub-menu?

Hi Paul

Since it got added in simple mode I guess you need to turn that off and then look in Paper UI under Configuration/Items.

Another way is to use the Karaf console and se them listed there.

ssh to your box and then
ssh openhab@localhost -p 8101 -oHostKeyAlgorithms=+ssh-dss
the password is habopen

openhab> items <- This command will give you all your created items. To find more commands just type “help”

Hope this helps.

Christian

Also, another way (to find an item name) is to browse to the thing and to the linked items that openHAB 2 created for you via Paper UI:

You need to disable Simple Mode for Item Linking to see the Linked items

Make sure that Simple Mode is disabled:

Thanks for everyone’s help.

I think the real question is how do I change “wemo_lightswitch_Lightswitch_1_0_221609K13013B1_state” to an alias or something, something I can use in the rules etc?

I don’t think that you can use aliases for item names
You could try to rename the existing or delete it and create manually a new one (don’t forget to link it to the appropriate thing channels)
