@drnavan Unfortunately I'm another who's pwd did a lot of wandering. We've also been called out to the home alarm going off courtesy of him, and the police calling a whatoclock in the night/morning having picked him up. He has a couple neighbours who have been great when he's knocked on their door in the middle of the night and had given them our phone numbers to call us to bring him back home. That might be something you could do.
In the end though, despite all the signs and gadgets to deter him, the best thing we did to stop the wandering was to lock the one door he used to wander out from (there are two other exits from his home) and this also meant someone had to move in just in case he needed escorting.
The locked door works but he now wanders around his home, even in the night. As long as he won't hurt himself or break something, we just let him get on with it. All the best!
