Issue Control Servo through dashboard

ESPHome
1

Following https://siytek.com/esphome-servo-example/#Configure-ESPHome
i’m having issues controlling a servo from an esp8266, D1 Mini. I have used a servo tester (from the same power source) to control the servo position and works, i think my issue is the esp device is not getting the input from the dashboard? i tried to add a log into the yaml to print the value but not sure if i did that correctly?

my aim is to have a few sensors for some garden automations, the other sensors are working fine and see them output on my dashboard. i can see the device in esphome is online and the servo moves on startup.

if anyone has any suggestions on what could help me that would be great!

What do the automation traces show when you adjust the input numbers?

Are there any errors in Settings → System → Logs related to these automations?

3

the only error in logs is when i reboot the device:

Logger: aioesphomeapi.connection
Source: runner.py:179
First occurred: May 28, 2023 at 20:05:23 (7 occurrences)
Last logged: 21:15:59

garden @ xxx: Connection error occurred: [Errno 104] Connection reset by peer
garden @ xxx: Connection error occurred: Ping response not received after 90.0 seconds

i guess the issue could be that the automation isnt loaded if it isnt in this screen?

image
image2206×1278 33.9 KB

but i added it via the file editor?

image
image2557×483 50.6 KB

and have rebooted since setting, and have no issues when in developer tools and check configurations

4

i tried creating it though the ui rather than pasting into the yaml but getting an error 500 with:

image
image2203×1284 70.9 KB

have to use the yaml editor otherwise the data is only allowing a float

5

if i change this (level) value then the servo moves! when the automation is run

image
image1372×825 27.6 KB

but unsure what is wrong to link it to the slider on my homepage

using

image
image1384×410 13.4 KB

i get ‘Error rendering data template: UndefinedError: ‘trigger’ is undefined’

6

super weird that it works now!
i edited the yaml back to how the format was origionally, did a soft reload, and now it magically works.

- id: '1685395498019'
  alias: New Automation
  description: ''
  trigger:
  - platform: state
    entity_id:

  condition: []
  action:
  - service: esphome.garden_control_servo
    data_template:
      level: '{{ trigger.to_state.state | int }}'
  mode: single

is the code in the automations yaml file

The problem was the first line of your automations.yaml file. The include in your configuration.yaml file would resolve to:

automation:
  automation:
    - alias: Write Servo Value to ESP
      trigger:
        platform: etc...

When it should be:

automation:
  - alias: Write Servo Value to ESP
    trigger:
      platform: etc...
