Replacement desiccant for Ayyeka Wavelet enclosures (WA00181) — four 10-gram packs per order.

Why it matters: the Wavelet is sealed to IP68, but every time the housing is opened for a battery change, a sensor swap, or a service check, humid air gets in. Fresh desiccant absorbs that moisture so it doesn't condense on the electronics when the enclosure cycles through day and night temperatures. Fit a new pack any time you close the unit back up, especially in humid climates and vault or manhole installations.

Servicing a unit? You'll likely also want a replacement battery.
