I'm helping a friend automate their house. They purchased Iris v2 and v3 contact sensors that'll come without magnets. Any recommendations on magnets that work well? I've heard the v3 sensors are finicky vis-a-vis magnet positioning.
I don't use Iris but I use "after-market" magnets successfully with other brands. I would think as long as they are the stronger rare-earth magnets, you should be good to go. Those are fancy. My only concern with the ones you posted is that they are mostly steel for protection with a thin ring of magnet. Know idea if that matters. I just go to Home Depot and stick them to frame w/ 3m tape.
