There's no way a smart switch can always match light state unless it's a momentary switch + light. I've not seen any smart switches which can mechanically actu

  Most hardwired smart switches close or open the circuit either electronically or with relays depending on supported load, so whether or not there is power to the bulbs is entirely dependent on the switch state. So yes, they can always match light state, ignoring the case of a burnt out bulb. This applies to e.g. Lightwave switches.

    Right, this is how I have my ESPHome-based switches wired. I thought you were referring to the mechanical state of the actual switch on the wall - I've gone with retrofit switch modules since I wanted to retain the tactile switch flip (just now they all work like dual-switches).
