Still not right

The gas measurements are still giving me trouble:

I’ve changed scales and plotted all values to better see what’s going on over a small time frame. The electricity consumption looks ok now (these are night-time values). But the gas measurements keep jumping up and down by a factor of around 5 all the time!

Maybe there’s a problem with the sensor readout – there are about 4 readings coming in per minute. Or perhaps the automatic idle transmission of packets every 10 seconds is interfering with this cycle?

I don’t know what’s going on… needs more work!
