Problem with automation sending a message with text and payload

Configuration
1

Hi folks,

back again as I’m learning fast what I want to achive with HA (really great tool).
Problem is that my knowledge at some points is still laking some levels :slight_smile:

First of all, I figured myself out (by reading many examples and documentations), how to read the correct SNMP values from my Windows Server to sensors :upside_down_face:

Now I want to send an automated notification via Telegram, when e.g. percent used disc space is >80%.
Fine, working.
Now I want to know which of my 3 discs firred the automation. Stuck :frowning_face:
Most probably I could use a lengthy 'if elif endif’ structure but I guess this can be done easier.

So, here is my most recent work:

- id: '1575363343504'
  alias: Disc full LRSERVER2
  description: ''
  trigger:
  - above: '80'
    entity_id: sensor.lrserver2_storage_used_percent_disc_c
    platform: numeric_state
  - above: '80'
    entity_id: sensor.lrserver2_storage_used_percent_disc_f
    platform: numeric_state
  - above: '80'
    entity_id: sensor.lrserver2_storage_used_percent_disc_g
    platform: numeric_state
  condition: []
  action:
  - data_template:
      message: Disc LRSERVER2 above 80%  {{ trigger.entity_id }}
    service: notify.telegram

If I just send plain text in the message like

 message: Disc LRSERVER2 above 80%

everything is working fine.

When using the {{ entity_id }} in the message I get this error in the log.

Error sending message: Can't parse entities: can't find end of the entity starting at byte offset 74. Args: (999047806, 'Disc LRSERVER2 above 80%  sensor.lrserver2_storage_used_percent_disc_g'), kwargs: {'parse_mode': 'Markdown', 'disable_notification': False, 'disable_web_page_preview': None, 'reply_to_message_id': None, 'reply_markup': None, 'timeout': None}

I’ve tried various options of brackets, quotes etc. (like in Automation Templating automation 2) but no success.

Who might shed some more light on my miserable life :joy:

Thanks upfront to these great people that monitor all us noobs and help so fast, like you did with me in the past days.

Did you try:

{{ trigger.to_state.entity_id }}

Hmmm, same result.

The text that has to be sent is already correct in the error log

'Disc LRSERVER2 above 80% sensor.lrserver2_storage_used_percent_disc_g'

Maybe the message is just too long??

Ok I just read that there seems to be a issue with underscore character in telegram notification.

Could you try this:

action:
  - data_template: >
      message: >
        Disc LRSERVER2 above 80%  {{ trigger.entity_id | replace('_','-') }}
    service: notify.telegram

Or this if the friendly name of the device doesn’t contain any underscore:

action:
  - data_template: >
      message: >
        Disc LRSERVER2 above 80%  {{ trigger.to_state.name }}
    service: notify.telegram

BINGO, that was tricky.

Maybe it would be easier to just send the last character of that entity_id string along with the static text.
Unfortunaltey I have no idea how to do something like (right (in_string ,1)) to get only the rightmost character in HA.

Does {{ trigger.entity_id[-1] }} work?

7

It needs to be

{{ trigger.entity_id[-1] }}

without “:”, your code will cut-off the rightmost character

Or the friendly name (if the sensors have one).

Yeah, I thought I fixed it before anyone saw. LOL.

Always my preference

Thanks again,

all three versions work!

Will keep them as reference in my automation.yaml for future use.

You can’t stop learning one new thing every day :slight_smile:
