All my self builds (fraction of the cost of this b-hyve devices that die like flies ) are still going strong, some have already 3 years of service
Out of curiosity I checked our local (average) weather against some random locations in Florida. The temperatures swings in both direction (hot and cold) are much more elevated. @RayHollister not sure where you are but your yearly median is probably around 15 to 35°C or some other numbers in Fahrenheit. At our spot we have a range from around 0°C up to 45°C (still no reason for devices to die )
i had a bhyve faucet controller that died - or rather ran through a fresh set of batteries in a couple of days and then wouldn’t work again even with a fresh set of batteries.
I believe it was due to water infiltration into the battery chamber. I found it was wet upon opening and there was some early corrosion on the battery terminals – even though there was a gasket to keep a good seal.
Unforunately because it was past warranty, Orbit couldn’t replace it so I bought a different, cheaper timer and am looking at building one - at least then I will own the problem of durability…
