why don't you have dual smoke and carbon monoxide detectors?
Many states are requiring both sensors now in their fie safety laws. All major detector companies sell nice little dual units. COVE sells a dual unit now for their very similar system. When I signed up for Simplisafe the rep told me 'you were working on having one' which I gather was not really true, but it did make the sale.
It seems like such a simple thign to do, which would make you lots of money in unit sales. As well as keeping up with what COVE is doing. SO why don't you make one?
