A device that I integrated over a rest API was not connected (wifi).
Because there is not information in the error message which source causes the error, you need to go trough your configuration.yaml file and check the rest API integrations.
Hi I have a similar problem but I am unclear where to find the error:
Logger: homeassistant.helpers.template
Source: helpers/template.py:2742
First occurred: 27 October 2024 at 18:05:22 (137348 occurrences)

Template variable warning: ‘dict object’ has no attribute ‘HCJR’ when rendering ‘{{value_json[‘CONTRACT’][‘HCJR’]}}’
Any ideas are greatly appreciated as this is filling my logs
