Electromagnetic Drawer Locks using Home Assistant and ESPHome

Let's talk about Electronic Mag Locks! In today's video we're taking a look at how we used electronic mag locks on all ten of the drawers in our van. We'll look at my choice for the magnets, micro-controller, driver board, and the ESPHome YAML configuration used to make it all work! As as bonus we look at the 3D printed case and custom aluminum mounting bracket I made to complete the setup.
