Hello Eric,

We don’t have any tutorials that shows exactly what you’re looking for… Which home automation controller/platform are you going to use (Node-RED, Home Assistant, etc)? Are you going to use MQTT?

If you merge these two Units together:

You can create a timer for the ESP32 that turns an output on after a X number of seconds. With the second tutorial you can create an MQTT connection with a Raspberry Pi that instead of turning an output on/off, it could receive a message to start a timer…
