Monitoring errors

[cbertoldi]

First of all I would like to thank you for this great project.

I managed to configure it and to monitor my pellets burner. The burner got stuck quite frequently in the last weeks and I would like to know if you already experimented with the error codes that are exposed. In the status response there is just one attribute that could be helpful ("error":65535). Do you maybe know if it would contain the error code that's displayed on the burner's display?

My idea would be to send some kind of notification with Home Assistant in case an error occurs, this way I could notice a problem before the water in the buffer gets too cold.
An alternative would also be to trigger the notification if the water temperature goes below a certain threshold, but that would be a bit too late.

OK, I think I found the answer: tonight the pellets vacuum got stuck again, and after the third error the attribute changed to "error":5043, which is the same error code I see on the burner.

I will think about an approach to monitor this from Home Assistant.

you should be able to monitor the attribute, by adding the systarest.yaml to your homeassistand configuration.yaml https://github.com/beep-projects/SystaPi/tree/main/helpers/homeassistant
That should give you a sensor in homeassistant, which you then can use with the alert integration or something similar https://www.home-assistant.io/integrations/alert/

Thanks, for the moment I solved it with an email notification, here is the code I used, in case it would be helpful for somebody else. The text is not correct, but my English vocabulary regarding heating systems, is not the best ;)

alias: Heating error
description: ""
triggers:
  - trigger: numeric_state
    entity_id:
      - sensor.systapi_error
    below: 65535
conditions:
  - condition: time
    after: input_datetime.next_notification_delivery
actions:
  - sequence:
      - action: notify.send_email_with_gmail_as_peleo
        metadata: {}
        data:
          message: >-
            Heating error: {{
            states('sensor.systapi_error') | string }}.
