why not access jellyfin From House B over VPN with House A

At man ment I do it with + adresses instead of alias. It works also.

Meanwhile I do not lile it anymore, that the caldav calendars are fully separated. Its not possible to have the flexibility I need for family management.

Prepare some money for a fresh start.

Mainly to be more flexible for new jobs to gain income. You may need money to be flexible at the beginning. E.g. for traveling. In some countries, it could be important to further pay some insurance. I would check in advance what you need and what not.

Thanks for the hint. Long ago I also used syncthing. At that time it not fit my needs. But in this case it may is a possibility.

Any best practises for excluding files in Home for syncing like .cache ?

As far syncthing does not come with a vfs.

All family member I support and provide with services use a Laptop. They are connected over wireguard. Solutions that depends on Network connections will not work.

I would like to check where some words appear and check in what context. EG, I search for my Home country orthe name of an Animal.

Does someone know what app allows me to create saved search / Search subscription?

Tetrapegic and children I personally know use Macrogal based medicine.
