Is there a thread for Smart Devices that don’t exist but should?
Let me start.
I would love a battery powered humidity sensor with a dry contact that could trigger my home’s Air make Up system (Air transfer system) (Zigbee, Zwave or Bluethooth)
Also on the list I would love a small simple battery powered dry contact switch (again Zigbee, Zwave or Bluethooth) that could trigger anything from a neutral lacking wall switch to battery power toys, to other low voltage devices.
