A smoke/CO2 I think is an obvious item for Wyze to add but I would love to be able to also use it as a white noise machine and a night light. I wish to install a white noise machine outside of my bedroom/bathroom area at the top of the stairs but it would be an awkward installation. It would also be nice for anyone who likes a little noise when they sleep as all bedrooms have smoke alarms. If the alarm is already using a speaker, adding the function to use it for a constant subtle white noise would be a nice added feature. Also would love motion detecting night light to be included.
