A constant frustration of mine is the easy ability to grant access to visitors and guests. We run an Airbnb in part of the house with lots of nice devices that could be controlled via HA. But, due to security concerns and my lack of time to build a separate interface, I have not tried to develop a method of access for them.
When I used SmartThings for home control, I used ActionTiles to create a secure dashboard on a kiosked iPad. That worked great and was super easy to set up. I would love to see this type of function in HA. Or maybe a partnership with ActionTiles? I honestly think HA dashboards could learn from the simplicity of ActionTiles.
The problem I have found with that (unless I am doing something wrong) is that it exposes tonnes of other stuff that would not be necessary or desirable for an Airbnb guest. The example above is all they see. When they touch the lock button, the door locks or unlocks, binary lights turn on or off with a simple press, dimmable devices, and a simple scroll bar appears on the screen.
My frustration with HA Dashboards is that getting rid of all the extra stuff is hard. For example, History, Settings, Related. There is often extra stuff on the device Info tab, like Attributes. Then there is the HA navigation bar itself and the related components that may be accessible. A streamlined interface can be achieved in HA with lots of add-ons and tweaking, but it isn’t particularly easy to do. The second part is security concerns around what might still be accessible even if hidden.
Then, as freekeys says, I created and pre logged in a guest user and removed all the side menu items.
Kiosk mode hides the side-bar, but if they did find it then there’s nothing to see other than the guest dashboard
