Feedback on daisy chained SPI Sensors
SPI doesn't define anything on data link level (i.e., how to interpret the data being transmitted), so a specific answer is only possible for a specific device. Each slave should specify whether it can be daisy-chained, and how the transmissions to daisy-chained devices should look like. Typically, devices which support daisy chaining either don't reply at all (i.e. they copy MOSI to MISO via a shift register), or they only reply to transmission with the right address, passing everything else along.

What is specified by SPI is chipselect behaviour. If you deassert chipselect, all slaves will ignore data and clock completely.
