This is product is discontinued and does not have a replacement yet. New product in development. What does that mean?

Unfortunately, Wink isn't the most open system out there.

Wink doesn't recognize any type of multi-level sensors; the ZSE19 Multisiren includes temperature and humidity sensor, so it qualifies as a multi-level device. But Wink also doesn't support many of the newer Z-Wave Plus devices based on the updated command classes.

If you're looking for a system that's more open and flexible, we'd recommend using looking into SmartThings, Hubitat, or Vera to use with your Multisiren.

Please let us know if you have any questions about compatibility! Our team is ready to help.
