Amazing piece of work by both of you! Thanks a lot for sharing!

due to self heating of the sensor

seems possible , the fact that the bmp ver is less "hot" tallies with its lower power use [hum sensor nearly doubles the consumption]

my esp code uses forced mode letting it sleep between readings and fares no better anyway, so maybe it is what it is

Just now when I started it up again, the humidity reading was way high, around 70%.

data sheet says writes to config reg 0xf5 may be ignored if device not in sleep mode, maybe por does not always achieve that.
cannot say i have seen any issues with humidity readings from esp code.
the pressure readings are consistent within 2hpa spread across the chips i have


i find just reading the config reg 0xf5 can cause the device to stop responding completely some times
