Ok guys,
i think i have a quick dirty solution that works for my installation (windows)
-
Download the following file an save it to your computer in any directory
openhab2-addons/bundles/org.openhab.binding.icloud/src/main/resources/fmipmobile.crt at master · mauryquijada/openhab2-addons · GitHub
If you can not download it, copy the content (—BEGIN CERTIFICATE…) in the clipboard and create a text-file and paste it into it. then rename the txt-file into fmipmobile.crt -
Download the icloud.binding file for Openhab 2.5 (it works with 2.4) from
JFrog
and save it in the same directory. -
Now open the Jar-File with Winrar or another Tools which can edit ZIP-Files (the jar-File is a zip-file)
Replace the crt-file in the jar-file with the new one you have downloaded in step1. -
Close the jar file and copy it in the addon-Folder of Openhab
Now the Things will go online (for another year)
