Thank you for the info. Though not sure this is a case - the switch publishes battery level on easy keypress. Moreover it was reporting 97% before I started this thread, and then same 97% appeared on the dashboard next day,
There might be a similar case happenning right now with all the temperature sensors I have. In the MQTT log there are sensor reports with different temperature and humidity data. These values are actual on the corresponding value page, but at the same time wrong (stale) on tha graph.
I am pretty sure there were values changes this morning. Here is a log:

Any ideas how to refresh the graph?
