Proposed Changes:

This change introduces the concept of having experimental settings in the YAML configuration. YAML configurations are not meant to be used by integrations, which should use always the configuration flow.

In that case, we use a not suggested method to provide settings we don't want to expose easily to end users. In this way we can ship settings we can add/remove/break based on the need.

With this change you can force HA to update sensors data even if previous/actual states are the same.

Testing:

Update your configuration.yaml with the following code:

econnect_metronet:
    force_update: true
