1.4 Third-party data loggers
In 2012, third-party data loggers with specifications and functionality equal to the orig-
inal Davis units emerged on the market. Reasonably priced, they offered a most wel-
come alternative to the overpriced Davis units. Even better, the third-party units were
the result of a community effort driven forward by dedicated Davis customers with a
keen interest in electronics and sharing technical knowledge.
Obviously, this development must have caused interesting reactions at the Davis
HQ in Hayward, CA perceiving their domain threatened by competitors offering
data logger units at significantly lower prices, they took some unfortunate steps to pro-
tect their market share.
Mainstream users probably wouldn’t even know there are third-party applications
and data loggers available, only emphasizing how wasted the Davis efforts at establish-
ing a data logger authentication scheme have been.
