I’m having issues getting my Tradfri set to work. I had originally experimented with the example settings I found in documentation etc and managed to create my own configurations which seem to work for a while only to somehow “reset” or change overnight. For example, I am now seeing log entries such as:
Cannot delegate command ‘ON’ for item ‘Light_Ceiling’ to handler for channel ‘tradfri:0220:gwb072bf2254e3:tLight:brightness’, because no thing with the UID ‘tradfri:0220:gwb072bf2254e3:tLight’ could be found.
2017-07-09 14:18:54.959 [WARN ] [ome.core.thing.internal.ThingManager] - Cannot delegate update ‘21’ for item ‘Light_Ceiling’ to handler for channel ‘tradfri:0100:mygateway:myDimmableBulb:brightness’, because no thing with the UID ‘tradfri:0100:mygateway:myDimmableBulb’ could be found.
I don’t have myDimmableBulb or mygateway anywhere in my configuration items, sitemap, things etc
I remember the myDimmableBulb being in the example for the Tradfri binding
Is there a way to “reset” or clear whatever cache is holding this information as it seems to confuse OH?
That is what the error is saying. You are referring to a channel ID in Light_Ceiling that doesn’t exist. Look in your .items files for a Light_Ceiling Item and make sure the channel ID is correct and look in PaperUI and see if there is a Light_Ceiling Item and make sure that the channel it is linked to is correct.
Since my initial post yesterday, I backed up my settings and ran “apt-get purge openhab2*” then reinstalled and did some basic configuration before restoring my settings and now it’s working fine. However, I still want to know f it’s possible to “clear” whatever cache OH holds these things in as I’m pretty certain I did not have them anywhere in my openhab-config folder.
