Detailed Description

Simple max filter.

Takes the max of the last <send_every> values and pushes it out every <send_every>.

Constructor & Destructor Documentation

MaxFilter()

esphome::sensor::MaxFilter::MaxFilter ( size_t  window_size, size_t  send_every, size_t  send_first_at  )

explicit

Construct a MaxFilter.

Parameters

window_size	The number of values that the max should be returned from.
send_every	After how many sensor values should a new one be pushed out.
send_first_at	After how many values to forward the very first value. Defaults to the first value on startup being published on the first raw value, so with no filter applied. Must be less than or equal to send_every.
