Not sure if this is possible with HA, but since everything is possible, let’s give it a try!
I want to set a date range in HA frontend, so I need some input button which allows me to enter a date.
The application is as follows: I have a Raspberry Pi digital picture frame which is connected to Home Assistant via MQTT to turn it off and on and to exchange some data (https://www.thedigitalpictureframe.com/control-your-digital-picture-frame-with-home-assistents-wifi-presence-detection-and-mqtt/). Now I want to extend the functionality to include a filter which would specify the date range for pictures that are shown. This would require me to input the values in HA somehow. I know how to pass them on, convert and whatever to my picture frame but I have no idea how to enter a date in Lovelace frontend. Any ideas, tipps that can get me started on the right track?
