FWIW I had a rough time the first couple of nights with the new sensor, too, but it does seem to have settled down. No “compression-or-whatever” lows last night even though I was lying on the sensor side. Saw some effect, but not to where it was dipping below the line and setting off alarms.
This DOES seem to be a new thing though. I’ve been using these suckers for a long time and have experienced the “normal” erraticism with bleeders as well as just not being able to pre-soak, and this was different.
Ah well. T1 is nothing if not an eternal learning experience.
