Calpak VBus®Touch vs Nonna for Elders

The Calpak-VBus®Touch app makes solar yield visible. In addition to a hydraulic scheme and a temperature progression chart, the solar heat gained will also be displayed. To visualise an individual system with VBus®Touch, a controller equipped with a VBus® interface and connected to the Internet by means of a Datalogger or Communication module is required. The basic version of the VBus®Touch app is available free of charge. Extended features will be available as modular add-ons which the user can individually combine.

Nonna is one app for both sides of the call. On your phone, you manage everything: build the family list, set up the elder's phone, and call whenever you want. On their phone the same app becomes something else: a screen of large family photos and nothing else. They just tap a photo and the call starts. No menus, no notifications, and no settings they can accidentally change. Set it up just once Install Nonna on their phone, log in with your account, and select "Their phone". It just takes a moment. After that, they'll never have to deal with emails, passwords, or login screens. One tap to call, one tap to answer They simply tap a photo to start a call. When receiving a call, the screen shows the caller's photo alongside one large "Answer" button. It's that simple. Zero confusion, just connection. Bring the whole family together Group calls let children, grandchildren, and grandparents join the same screen. Everyone appears with a familiar photo and name they easily recognise. Manage everything remotely Update a photo, edit a name, or add a new family member - all from your own phone. Changes appear instantly on theirs, so you'll never need to handle their device again. Designed for eyes and ears that need a little extra help Large buttons, high-contrast text, and volume they can actually hear. The interface decisions were made for someone who is eighty, not someone who is thirty. A secure connection Calls go directly between the devices, and each family's account is separate from every other. The two sides don't need the same kind of phone.
