Lowest latency input (self.homeassistant)

I'm using a ZigBee button to call an automation which notifies via Pushover and Alexa. Works fine.

I'd like to reduce latency and use a physical button. I can use a Pi, ESP32 or similar to respond to a closure and tell HA.

What's the lowest latency input to HA? My MQTT server is separate so I'm thinking an HTTP post direct into HA might be best.

Is there anything faster? HTTP is fast enough in my testing, it's an experiment as much as anything else.

If you can hard wire an ESP32 via Ethernet that would probably be best. You could also get better latency with an ESP32 over WiFi. However, a ZigBee button should be pretty low latency already.

Anecdotally I get perceptibly instant response from an ESP32 over WiFi.

Perceptibly instant is fast enough for me :)

What's the method you're using to communicate with HA?

Im guessing the latency here isnt zigbee, but the two cloud components that follow the button.
