sorry for that late answer.
In v2.2.0 there is a problem with the app formular of some apps that could only be instantiated once. E.g. 'Cron' - the app is still active (if it was already added) but the form that is responsible for editing and adding this app is broken.
This is fixed since v2.2.1-rc4. Also we've find out that the time format that you could enter in the apps 'Logical Rules', 'Scheduled Scene' and 'Smart Light' isn't working correctly. These fixes will be available soon via update in online app store and also (if released) in v2.2.1.
As you have already correctly identified it is necessary to check the timezone of your box. Usually it comes with GMT +/-0 so it is necessary to add your timezone to get the correct timezone offset from the system. We will integrate this in smarthome ui in the near future. But meanwhile you could do the following things:
- like [Spacerat] via console at your box with command 'sudo raspi-config' -for more instructions please use this link : https://www.raspberrypi.org/documentati ... -config.md
-headline: 'Internationalization Options'
- enter http://[IPOFYOURRASP]:8084 go to Advanced > System > Timezone and add your timezoneinfo there. You could google it or use this link http://pellepim.bitbucket.org/jstz/
(you will see it in the grey banner)
A restart isn't necessary.
If it doesn't work anyway please let us know. Thanks for your support.
