Just installed a 3-way switch using a Red Series Dimmer and an Accessory Switch in a non-neutral setup. It is working fine and can properly be controlled from the main switch, the accessory switch and from home assistant.
When the light is on though, the main switch (LZW31-SN) is getting very warm/hot. The black metal is essentially too hot to touch. I’d estimate >120 F. This seems too hot to be right. I rechecked the wiring and everything seems correct without any shorts, touching wires, etc.
Any ideas how to further troubleshoot or fix?
