Error during setup of component rest → Resource not set for RestData

erik7 · November 3, 2022, 10:27am

Since update to 2022.11 I receive the following error during setup of component rest:

Unable to prepare setup for platform rest.sensor: Unable to set up component.

2022-11-03 10:36:02.024 ERROR (MainThread) [homeassistant.setup] Error during setup of component rest

What exactly does it mean, but more important, how can this be solved?

EDIT: After several restarts sensors are OK now.

Hi,
I have the same issue.
Are you sure you didn’t change anything between restarts?
I don’t know how to solve this, right now I did several restarts but that didn’t help.

Thanks

I managed to solve this by changing my configuration: I had the rest sensor under “sensors” now is under “rest” and everything works.

fedot · November 4, 2022, 10:51am

This worked for me as well, thanks for providing a fix.

I have other problem after moving the rest sensor in the Rest section, so I rollback to the previous configuration and opened an issue in GitHub, since this was working fine and not it isn’t. Looks like a regression to me.

Hi,

This is the second time that I tried to update to 2022.11.2 but get the Rest Sensor errors. I previously rolled back to 2022.11.1 so that my HA instance could continue to operate. I read through this post and the linked Issue #81551 and thought maybe the issue had been addressed by the core changes. But today I tried to update again and faced with the same problems that the Rest Sensor can not be set up on boot.
It is clearly an issue with my REST templates configuration, but I dont clearly understand what I need to do. I checked the Rest documentation but its still not clear to me. I have several Rest sensors throughout my configuration that probably need updating.

Could anyone point me in the right direction with an example of the acceptable configuration?

Your configuration is wrong, please have another look at the docs.

You should avoid using multiple top-level keys if you can:

Some integrations support multiple top-level !includes, this includes integrations defining an IoT domain, e.g. light, switch, sensor as well as the automation, script and template integrations, if you give a different label to each one. Configuration for other integrations can instead be split up by using packages. To learn more about packages, see the Packages page.

source

This might work for the rest platform, but if you have them in one place, referencing rest: multiple times isn’t neccessary.
Have a look at the first code block in the docs. You’re missing the - in front of every rest sensor. So your first example should be:

rest:
  - resource_template: "https://api.octopus.energy/v1/products/AGILE-OUTGOING-19-05-13/electricity-tariffs/E-1R-AGILE-OUTGOING-19-05-13-A/standard-unit-rates/?period_from={{ now().year }}-{{ now().month }}-{{ now().day }}T{{ now().hour }}:{% if now().minute <30 %}00{% else %}30{% endif %}&period_to={{ now().year }}-{{ now().month }}-{% if (now().hour == 23) and (now().minute >=30) %}{{ now().day+1 }}{% else %}{{ now().day }}{% endif %}T{% if (now().hour == 23) and (now().minute >=30) %}00{% elif now().minute >=30 %}{{ now().hour+1}}{% else %}{{ now().hour}}{% endif %}:{% if now().minute >=30 %}00{% else %}30{% endif %}"
    scan_interval: 1800    
    sensor:
      - name: "Export Price" 
        value_template: "{% if is_state('input_boolean.go_tariff','on') %}4.1{% else %}{{ value_json.results[0].value_inc_vat|round(2) }}{% endif %}"    
        unit_of_measurement: "p/kWh"

      - name: "Export Price Pounds"
        value_template: "{% if is_state('input_boolean.go_tariff','on') %}0.041{% else %}{{ value_json.results[0].value_inc_vat / 100 }}{% endif %}"    
        unit_of_measurement: "£/kWh"

Then just put the other rest stuff under the same rest: key, don’t add another one. E.g.:

rest:
  - resource_template: "https://api.octopus.energy/v1/products/AGILE-OUTGOING-19-05-13/electricity-tariffs/E-1R-AGILE-OUTGOING-19-05-13-A/standard-unit-rates/?period_from={{ now().year }}-{{ now().month }}-{{ now().day }}T{{ now().hour }}:{% if now().minute <30 %}00{% else %}30{% endif %}&period_to={{ now().year }}-{{ now().month }}-{% if (now().hour == 23) and (now().minute >=30) %}{{ now().day+1 }}{% else %}{{ now().day }}{% endif %}T{% if (now().hour == 23) and (now().minute >=30) %}00{% elif now().minute >=30 %}{{ now().hour+1}}{% else %}{{ now().hour}}{% endif %}:{% if now().minute >=30 %}00{% else %}30{% endif %}"
    scan_interval: 1800    
    sensor:
      - name: "Export Price" 
        value_template: "{% if is_state('input_boolean.go_tariff','on') %}4.1{% else %}{{ value_json.results[0].value_inc_vat|round(2) }}{% endif %}"    
        unit_of_measurement: "p/kWh"

      - name: "Export Price Pounds"
        value_template: "{% if is_state('input_boolean.go_tariff','on') %}0.041{% else %}{{ value_json.results[0].value_inc_vat / 100 }}{% endif %}"    
        unit_of_measurement: "£/kWh"

  - resource_template: "https://octopus.energy/api/v1/tracker/G-1R-SILVER-2017-1-A/monthly/future/12/5320/"
    sensor:
      - name: "Gas Price Pounds kWh"
        value_template: "{{ value_json.periods[0].unit_rate / 100 }}"
        unit_of_measurement: "£/kWh"

  - resource_template: "https://api.octopus.energy/v1/products/AGILE-18-02-21/electricity-tariffs/E-1R-AGILE-18-02-21-A/standard-unit-rates/?period_from={{ now().year }}-{{ now().month }}-{{ now().day }}T{{ now().hour }}:{% if now().minute <30 %}00{% else %}30{% endif %}&period_to={{ now().year }}-{{ now().month }}-{% if (now().hour == 23) and (now().minute >=30) %}{{ now().day+1 }}{% else %}{{ now().day }}{% endif %}T{% if (now().hour == 23) and (now().minute >=30) %}00{% elif now().minute >=30 %}{{ now().hour+1}}{% else %}{{ now().hour}}{% endif %}:{% if now().minute >=30 %}00{% else %}30{% endif %}"
    scan_interval: 1800    
    sensor:
      - name: "Import Price"
        value_template: "{% if is_state('binary_sensor.power_hour','on') %}0.0{% elif is_state('input_boolean.go_tariff','on') %}{{ 7.5 if is_state('binary_sensor.go_cheap','on') else 40.13}}{% else %}{{ value_json.results[0].value_inc_vat|round(2) }}{% endif %}"
        unit_of_measurement: "p/kWh"

Thank you for the guidance and assistance. I made the changes to the REST sensors nd then made a back up and attempted the update to 2022.11.2 After the update there is this warning:

Any idea what it means about being merged? currently my HA setup is compartmentalized in to /config/packages/systems with separate folders for items to give clarity, something like this:

I did read that the system tries to put all the REST items in to a single file…is that what its trying to do here?
