Thank you both sabre666 and Private for your response.
I am using openHAB 3.4 at present, in a FreeBSD jail, configuring via the GUI. I also posted a question under " Alarm Decoder keypad item, how to send command? "
The section from org.openhab.core.items.Item.json reads as follows:
"AlarmKeypadAlarmDecoder_KeypadCommand": {
"class": "org.openhab.core.items.ManagedItemProvider$PersistedItem",
"value": {
"groupNames": [
"AlarmKeypadAlarmDecoder"
],
"itemType": "String",
"tags": [
"Point"
],
"label": "Keypad Command",
"category": "Command"
}
},
I am not sure how to translate between text configuration and GUI configuration, but over the next week or so I will experiment and post back what I tried and the results.
