Hi, This is my first day of using ESPHome to code my nodemcu, connected with a SR04.
I am using it to find water level of my 2meter deep tank. After reading documentation and forums I was able to configure it and it show perfect calculations.
Now I want to also show the water present in the tank in “Liters”.
sensor:
- platform: ultrasonic
trigger_pin: D0
echo_pin: D1
unit_of_measurement: "%"
icon: "mdi:water-percent"
timeout: 4m
accuracy_decimals: 0
update_interval: 60s
name: "Overhead Water Tank"
filters:
- lambda: return (1-((2-x)/2))*100;
- filter_out: nan
I have two options either to reuse the above code and change the lambda formula for liter calculation.
Or I read somewhere that I can use “platform: template” or something like that to use the data from previous code and process it in a different way and feed it to the home assistant.
I am unable to find any forum post or documentation on this. Can somebody guide me with this?
Thanks
Akash
