ESPHome RFID API Through Node-RED

Earlier this year I wrote about using web actions on the Fanvil i20S door phone to send information into Home Assistant. Today we’ll look at the other direction: how Home Assistant can communicate with the i20S to unlock the door or trigger a call.

I will build a small ESPHome-powered RFID reader that will communicate with Home Assistant to record logs and perform actions.
