The PiWire card only offers basic ESD protection. While suited for everyday indoor applications, this ESD protection is not capable of protecting the one wire host adapters and the Raspberry Pi against the effects of nearby lightning strikes, especially when using one wire devices and cabling outdoors (for example weather stations). When connecting outdoor equipment and cabling, additional ESD protection circuits are necessary. More information about this can be found in the manual.
