Error notifications - e.g. E02 error?

[c-soft]

I’m getting E02 error every now and then due to clogged filter, or other issues.

Would be great to get notification from Home Assistant (or otherwise) when this happens.

I’ve looked through all the states available but couldn’t find any indication.

Is it possible somehow?

There are multiple ways to do this, but one method is to create a sensor that mirrors whatever is on the display and make an automation that sends a notification if the sensor is E02.

mqtt:
  sensor:
    - name: "Layzspa Display"
      unique_id: "sensor.layzspa_display"
      state_topic: "layzspa/message"
      icon: mdi:fit-to-screen
      value_template: >-
        {% set ASCII = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx !x#$%&'()*+`-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz" %}
        {% set ch1=ASCII[value_json.CH1] %}
        {% set ch2=ASCII[value_json.CH2] %}
        {% set ch3=ASCII[value_json.CH3] %}
        {{ch1}}{{ch2}}{{ch3}}
      availability_topic: "layzspa/Status"
      payload_available: "Alive"
      payload_not_available: "Dead"

This is great news - I have upgraded to the beta and can now see the error field but I can't setup automation based on it, for some reason it's not showing in the list of selectable entities in HA - do you know why that might be?

[visualapproach]

need a restart? Check the entity name under entities, and check in developer/states for "error". It should show there

@chumleychuff
Try this (name of sensor may vary):

trigger:
  - platform: state
    entity_id:
      - sensor.layzspa_error
    to: "2"

Thanks Skeletorjus - this is what worked for me:

alias: Skeletorjus Trigger
description: "Skeletorjus Trigger"
trigger:
  - platform: state
    entity_id: sensor.layzspa_wifi_controller_layzspa_error
    to: "2"
condition: []
action:
  - service: notify.persistent_notification
    data:
      message: LayZSpa - Error Code has changed - Skeletorjus
      title: LayZSpa - Error Code has changed - Skeletorjus
  - service: notify.mobile_app_myphone
    data:
      message: LayZSpa - Error Code has changed - Skeletorjus
mode: single

Along with the "sensor.layzspa_display" that @Skeletorjus posted, I've also added this into my templates.yaml file.

- binary_sensor:
    - name: Hot Tub Error
      icon: mdi:alert-circle-outline
      delay_off:
        seconds: 10

        {% set errors = {

          {{ states('sensor.layzspa_display') | capitalize }}

          {% set display = states('sensor.layzspa_display') %}
          {% set error = {
              'e01' : "Lay-Z-Spa pump is experiencing a water sensor issue.",

              } %}
          {% if is_state("binary_sensor.hot_tub_error", "on") %}
          {{ error[display] }}
          {% else %}
          null
          {% endif %}

It's a binary sensor that shows if there is an error or not - on or off.
There are then attributes included that show the:

• Error Number
• Error Reason (as per the Lay Z Spa troubleshooting guide)

This is then used in an automation to send a home assistant notification to my phone using a custom notification script.

  title: Hot Tub Error - {{ trigger.to_state.attributes.error_number }}
  message: Warning. {{ state_attr('binary_sensor.hot_tub_error', 'error_message') }}

As always, I'm sure there are improvements to be made here, but I am looking forward to the official built in error monitoring that @visualapproach mentioned!
