I have searched but was unsuccessful in finding a solution. I have an ESP8266 with ESPHOME installed on it. There are 3 sensors and 1 buzzer connected to the ESP8266. I want to create an automation that will trigger the buzzer when certain parameters go out of range. For example, if the water temperature exceeds 75 degrees, I want the buzzer to sound. Is this achievable with ESPHOME and HA Automation? Here is my current YAML source code; any guidance would be much appreciated.

It all comes down to whether its a passive buzzer or not. If you dont know because you didnt build the circuit yourself then if you could identify the board name or even a picture.
I struggled for 10 minutes getting the format/spacing correct on what you gave me. I finally got it and it works like a charm. So this is done via the yaml file and not in the automation area correct? I need to add other alerts like if water is below 65F , then buzzer. If I want to setup email alerts, that would be done in the automation area and or in the yaml file right?
Below is what I put in and it worked perfectly. Your assistance is very much appreciated.
I do have one more thing I need help adding. I have a water float sensor. It is a 2 wire. It’s either on or off. How can I add the same feature to sound buzzer if the state is changed to off?

Esphome is actually working fabulously standalone. Web Server and Automations, HTTP api and MQTT is all what I really need. I don’t need fancy dashboard on my wall.
Only thing I have ever missed is numeric input on the web server.
Few Esphomes are taking care of my PV system, power diverter for hot water, ble thermo-hygrometers, heat pumps, some switches and outlets…
