Got a new victim:
AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
A: outside temp stuck at -40?

It's cold here at times in Canada, but not that cold!
B: stuck at some temperature and maybe updating once in 12 hrs or so.

Easy solution is to go to AcuRite website and purchase the sensor. Right?...
