I have created an esphome device that rings my existing chime that is triggered when somebody pushes the Reolink video doorbell. The hardware is based on an esp8266 (d2 mini). This device is connected using D2 to a relay. The relay is triggers the chime.
The device is triggered by an automation that publishes an mqtt message. Only an On message is send. The chime turns itself off.

The Esphome is code is below.
The chime automatically turn off after a programmable delay.
I have replaced some of the keys with ā***ā that were generated when the device was created.
