Wired doorbell broke (a semi fancy one, with a gate opener and a camera, but totally proprietary and old). I don't have the will to troubleshoot what/why. I don't want to pay someone to fix it either. To me it's not worth getting it fixed. Not too sure what we'll settle on eventually but meanwhile I put one of these cheap doorbells you can find on Amazon: a button (with a little battery) at the door/gate and then, inside, something you plug into an electrical outlet. They work but they're not that great. It's only approx 20 meters / 65 feet and yet it regularly fails (one time out of five?). People who "know" know they have to press long and hard on the button, and try, say, three times (if it fails 20% of the time and you press three times, there's only a 0.8% chance it won't ring even once). I should probably add a little message below the button: "Please ring three times". Low tech way to fix the brittle system I guess.
