I’ve used Fuel streams with SmartThings for a long time, and never had any problems with logging tons of data points and having them graphed on the Fuel dashboard.
With Hubitat, it seems if I try to display more than ~30kb of Fuel stream data, something times out.
This is probably due to constraints on Hubitat’s processing ability, or some limit to Hubitat response size.
Feature request: default all Fuel Streams on Hubitat to be limited to 30kb by default.
I just manually made that change to about 30 scripts, and now my graphs are displaying correctly.
