I’d like to include project information, name and version, in code that I’m writing for a salt level sensor. I though it was a simple matter of adding a project section to the yaml file. Everything I’ve read suggests the following should work;
esphome:
name: salt-level-sensor
platform: esp8266
board: d1_mini
comment: Water Softener Salt Level Sensor

name: "Water Softener Salt Level Sensor"
version: "salt-level-sensor_2022_08_26_01"

switch:
- platform: restart
name: "salt_level_sensor Restart"
# Enable On-Board Status LED.
status_led:
pin:
# Pin D4
number: GPIO2
inverted: true
When I attempt to install the file using ESPHome, I’m presented with an error
project name needs to have a namespace.

I’ve searched the forum without finding a solution. Why is this error occurring?
Hi @rcblackwell , is it possible to have the whole code? I am trying to use this Salt level sensor for water softener in Home Assistant with ESPHome – ADONNO but I am getting the following error:
[17:02:00][D][ultrasonic.sensor:036]: ‘Saltlevel in percent’ - Distance measurement timed out!
[17:02:00][D][sensor:126]: ‘Saltlevel in percent’: Sending state -nan % with 2 decimals of accuracy
Sure! I’ve modified code structure since first posting for help. I’m using ‘substitutions:’ which allowed me to create a file to use as a template for each new project. The code below is functioning on my salt-tank.

Thank you so much for sharing the code, I like the substitution idea.
So I copy pasted exactly everything and I am ending up with the same error:

How can I add, inverted: true for both GPIO4&5, maybe this could resolve the issue… cos I can’t think of any other thing. I am using a D1 mini and a AZDelivery HC-SR04 ultrasound sensor…
