Extreme heat would "kill" cigars (causing beetles to develop and have open bar rave party). A drop in temperature won't (would usually only cause a drop in RH). You are safe. (assuming it wasn't like that for weeks or months.)
To come back on old school vs new school technology. Anything technology messed up once in a while. It's normal. I would advice to check periodically (even if you have the best of the best).
I tend to avoid the "made in china" stuff, especially when it comes down to measurements or monitoring devices. A good example in regards to cigars is the hygrometer. Once I receive my cabinet, I would go for a NIST certified hygrometer rather than the cheap ones found everywhere (prone to improper reading and requiring calibration). You can also find excellent analog hygrometers (made in germany).
