«There are many commercially available sleep systems. A minimum of 16 channels must be available»:
“Polysomnography typically records a minimum of 12 to 16 physiological channels, though modern laboratory systems frequently use 22 to 32 physical channels to capture comprehensive neurophysiological and cardiorespiratory data. It requires continuous attendance by a trained polysomnographic technologist. [1, 2, 3, 4, 5, 6]”

has built a sleep lab for less than $1000 with OpenBCI:
The instruction can be found here here:
So it should in theory be possible to build with OpenBCI a «commercially available sleep system» with 16 channels. SpiSOP is a Matlab software. But there is also sleep software in Python available. We did not find a straightforward device and solution which is somewhere published in a paper yet. So study the literature for further information.
