Dimmer values are not updated on Basic UI

  • Platform information:
    • Hardware: Raspberry PI 3
    • OS: Raspian 8 (jessie)
    • Java Runtime Environment: 1.8.0_201
    • openHAB version: 2.5

I setup a simple dimmer like this in my items file - no rules or complexity attached:
Dimmer NoiseProtection “Master Volume Max [%d %%]” (GRule)

I added the item into my sitemap:
Default item=NoiseProtection

Whenever I change the dimmer, it’s getting only updated on Basic UI after I press “F5” for refresh. In the iOS mobile app it works like a charm.

Change the dimmer to low, it still shows 56%.
After refresh, it shows the correct value --> 15%.

Any clue?

Check in openhab.log for any sitemap related messages.

Events.log (not reflecting 100% the example values above).

2019-12-31 10:42:17.198 [ome.event.ItemCommandEvent] - Item ‘NoiseProtection’ received command 26

2019-12-31 10:42:17.205 [vent.ItemStateChangedEvent] - NoiseProtection changed from 68 to 26

No info in openhab.log.

So as far as I understand this only happens when you are in the web browser, right?
Try to disable the cache.


The Browser Cache or OH Cache? :slight_smile:

First try the browser cache. If that doesn’t work try it with the OH cache (and clear out the browser cache again too to prevent false-negatives)

Browser Cache helped! :slight_smile:
Easy catch, but anyhow, thanks a lot!

You are welcome. Remember when you don’t see anything in your logfiles, then try to clean out every cache you can think off :slight_smile:
