OH3.4: trend line sampling of trend item not working

Tuny · January 2, 2023, 3:42pm

I recently updated from the lastest Milestone Release to openHAB 3.4.0.

Now I am facing the problem that the Trend Line Sampling parameter in the widget options is not working anymore.

See an example here: trendSampling: is set to “5” (minutes).
Before Update (all good):
vorUpdate
After Update (just a straight line):
nachUpdate

Anyone else facing similar problems?
How can I debug this?

Thank you. BR

I found the error:
When defining the “Trend Line Sampling” the number in the yaml is interpreted as string:

This is not working.
The quotes has to be removed like here:

After that it is working as expected.
I think this is a bug.

## The problem The "Trend Line Sampling" parameter in the Cell Configuration does not work out of the box. When looking at the yaml the value seem to be parsed as string (with quotes). But in this case the parameter is not interpreded. You need to remove the quotes, then it works. See also here: https://community.openhab.org/t/oh3-4-trend-line-sampling-of-trend-item-not-working/142841 ## Steps to reproduce Create a layout page and add a Label Cell. Then go to Confiugure Cell and define a Trent Line Item with a "Trend Line Sampling" parameter. When saving the settings the Trent Line Sampling will not work. You have to remove the qoutes in the yaml. After that it works. ## Your environment ```txt runtimeInfo: version: 3.4.0 buildString: Release Build locale: de-DE systemInfo: configFolder: /etc/openhab userdataFolder: /var/lib/openhab logFolder: /var/log/openhab javaVersion: 11.0.11 javaVendor: Azul Systems, Inc. javaVendorVersion: Zulu11.48+21-CA osName: Linux osVersion: 6.0.13-meson64 osArchitecture: aarch64 availableProcessors: 4 freeMemory: 317492536 totalMemory: 725614592 startLevel: 70 bindings: - androiddebugbridge - astro - avmfritz - comfoair - doorbird - evcc - exec - habspeaker - httplistener - hyperion - ipcamera - knx - lametrictime - miele - mielecloud - modbus - mqtt - network - openweathermap - shelly - smartmeter - smartmeterosgp - solarforecast - squeezebox - synologysurveillancestation - systeminfo - tr064 - viessmann - wled clientInfo: device: ios: false android: false androidChrome: false desktop: true iphone: false ipod: false ipad: false edge: false ie: false firefox: true macos: false windows: true cordova: false phonegap: false electron: false nwjs: false webView: false webview: false standalone: false os: windows pixelRatio: 1 prefersColorScheme: light isSecureContext: false locationbarVisible: true menubarVisible: true navigator: cookieEnabled: true deviceMemory: N/A hardwareConcurrency: 2 language: de languages: - de - en-US - en onLine: true platform: Win32 screen: width: 1920 height: 1080 colorDepth: 24 support: touch: false pointerEvents: true observer: true passiveListener: true gestures: false intersectionObserver: true themeOptions: dark: light filled: true pageTransitionAnimation: default bars: filled homeNavbar: default homeBackground: default expandableCardAnimation: default userAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:108.0) Gecko/20100101 Firefox/108.0 timestamp: 2023-01-10T20:27:55.764Z ```
