Polling interval in Home Wizard app changed after integrating with Home Assistant?

Using a p1 meter, and the Home Wizard app.

After integration with Home Assistant (picture “Yesterday”), the home wizard app shows spiky graphs. Looks like the polling interval was set to a lower value (?). When I revoked the local API access (“today”), the graph behaviour didn’t return to what it used to be (picture “Sunday”).

Has anyone seen this before? Any fix?

/edit: as a new user, I can only use one embedded image in a post. I’ll try to show in the reply section.

Ok. Solved. This was just an unfortunate combination of events. When WiFi signal is low, the P1 meter switches to a lower update frequency. That’s what happened here.
