Irregular telemetry?

[zestysoft]

I've started graphing the telemetry coming from a pair of airgradients using this firmware and noticed that the values recorded aren't in a regular cadence. I think what I'm seeing is that if the value doesn't change from the last reported value, it won't report it. The problem is that even though I have a setting that "connects the dots", if the value doesn't change for the duration of the scope of the graph, I'll get "No data" instead. Given that these things aren't powered by a battery (I assume that's the reasoning behind this -- to conserve power?) is there a way to force the units to always report all values on a regular cadence?
