For example, if one sensor has a heartbeat of 30s, and another at 1min, when i enable real time on the dashboard, will it always refresh at 30s or the lowest heartbeat settings?
Good day @alvinphee,
I hope this note find you well.
If you have the real-time enable in the Dashboard yes, it will update every time you send a new value. To avoid exceeding the consumption of dots you can lower the frequency of data sending or disable the real-time of the dashboard and only request the date span you need to see.
Please let me know if you have additional questions.
