When your son gets a very nice analog Märklin railway from his grandfather (who got it from his father) but he really wants to use his tablet to control some parts of his new layout :-)
In the video you will see that the turnouts are controlled by the DK50018, we added some streetlights and a Dutch railway signal. They can all be controlled through the Digikeijs APP.
