[Home Assistant] Display Battery devices, sorted by battery status

 , , , , ,

Simple and handy card, to display devices/entities of a specific type. Thanks to this card, it is no longer necessary to add new battery devices manually.

https://github.com/thomasloven/lovelace-auto-entities

    type: custom:auto-entities
    card:
      show_header_toggle: false
      title: Battery status
      type: entities
      state_color: true
    filter:
      include:
        - attributes:
            device_class: battery
          state: <= 100

[Android] Upgrading LineageOS 18.1 to 19.1 on my Xiaomi Mi 8 (dipper)

 , , , , , , , , , ,

Install the Android Debug Bridge (ADB)

https://wiki.lineageos.org/adb_fastboot_guide.html
https://github.com/M0Rf30/android-udev-rules#installation

# check if device is found
adb devices
# reboot into sideload modus
adb reboot sideload

Or manually boot into TWRP recovery, holding Volume Up + Power when the phone is off. Navigate to Advanced -> ADB Sideload.

Update MIUI Firmware

Following the docs, I first had to check the Firmware version. V12.0.3.0.QEAMIXM was required, and I already had it installed.
If you’re on an older version, download the right MIUI Firmware for your device from https://xiaomifirmwareupdater.com/firmware/dipper/.
Flash the new Firmware via TWRP or via ADB sideload.

adb sideload fw_dipper_miui_MI8Global_V12.0.3.0.QEAMIXM_7619340f8c_10.0.zip

Download and flash new LineageOS image

I’m using the LineageOS fork LineageOS for microG. Download it from here: https://download.lineage.microg.org/dipper/ (MI 8 = dipper)
The upgrade steps are the same as for the official rom: https://wiki.lineageos.org/devices/dipper/upgrade. In my case only flashing the new image.

adb sideload lineage-19.1-20221217-microG-dipper.zip

[CAP] Fiori Elements – Add section with PDFViewer

 , , , , , ,

I have a CAP Service that provides a PDF file that I needed to display in a Fiori Elements frontend using the sap.m.PDFViewer. The viewer should be placed in a section on the object page after navigating from the ListReport main page.

My CAP Service has the following annotations to provide the PDF.

  entity pdfFiles : cuid, managed {
    content            : LargeBinary @stream @Core.MediaType: mediaType @Core.ContentDisposition.Filename: fileName @Core.ContentDisposition.Type: 'inline';
    mediaType          : String      @Core.IsMediaType: true;
    fileName           : String      @mandatory;
  }

Add a custom section to your view following this example: https://sapui5.hana.ondemand.com/test-resources/sap/fe/core/fpmExplorer/index.html#/customElements/customSectionContent
Two steps are necessary.

1. Add a new section via the manifest. The template path should match your app namespace.

        "ObjectPage": {
          "type": "Component",
          "id": "ObjectPage",
          "name": "sap.fe.templates.ObjectPage",
          "viewLevel": 1,
          "options": {
            "settings": {
              "editableHeaderContent": false,
              "entitySet": "pdfFiles",
             "content": {
                "body": {
                  "sections" : {
                    "myCustomSection": {
                      "template": "sap.fe.core.fpmExplorer.customSectionContent.CustomSection",
                      "title": "{i18n>pdfSection}",
                      "position": {
                        "placement": "After",
                        "anchor": "StandardSection"
                      }
                    }
                  }
                }
              }
            }
          }
        }

2. Add the section content by defining a new fragment in the file CustomSection.fragment.xml

<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m" xmlns:l="sap.ui.layout" xmlns:macro="sap.fe.macros">
	<ScrollContainer
		height="100%"
		width="100%"
		horizontal="true"
		vertical="true">
		<FlexBox direction="Column" renderType="Div" class="sapUiSmallMargin">
			<PDFViewer source="{content}" title="{fileName}" height="1200px">
				<layoutData>
					<FlexItemData growFactor="1" />
				</layoutData>
			</PDFViewer>
		</FlexBox>
	</ScrollContainer>
</core:FragmentDefinition>

On the ObjectPage you will now have a new section containing the PDFViewer.
