I really wish there was a zwave (or zigbee) detector that could be wired. I do not want to revert back to battery when I already have 8 wired detectors. I do have a relay hooked up, as per the thread below. But it would be great to have room level information for smoke detectors, just like the Nest Protects. I actually like the Nests a lot due to their functionality, but I do not like how much they have locked down their ecosystem. Yes, they have some IFTTT, but they have not really wanted to move beyond that…which stinks. Time for someone to step in and fill that void.
