I haven't actually built with that specific patch, but based on some
debug printfs I added, I conclude it would print nothing when
attaching uthum0, and print "sensor type 0 unknown" attaching uthum1.
More specifically, uthum0 is ignored because sc->sc_flen is 0. Then,
uthum1 is ignored because the signature read from the device in
uthum_check_sensortype() is 0x57 0x5a 0x14 0x00 0x14 0x00 0x53 0x00,
which matches neither of the two signatures the code checks for.
If I change uthum_check_sensortype() to accept the 0x57 0x5a 0x14 0x00
0x14 0x00 0x53 0x00 and return UTHUM_TYPE_SHT1x, I get the following
output from envstat:
Current CritMax WarnMax WarnMin CritMin Unit
temp: 28.040 degC
