Shelly 1 and Plus 1 (the gen 2 device) allows you to separate the relay from the switch and expose both via API or MQTT.
That's how I have my lights setup - normal light switches (switched live) will toggle the switch sensor which is picked up by HomeAssistant which then either toggles the relay (for non smart lights) or sends a command to a light group (Zigbee IKEA Tradfri bulbs, using a Sonoff Zigbee dongle for comms) to turn on or off.
The only issue you might have is that they require a neutral, so unless you have a neutral behind each switch you'll need to put the Shelly elsewhere, either in the light fitting or ceiling (in my case).
