• Question : Does it require a Z-Wave hub?
  Answer : Yes, a Z-Wave hub is required.
• Question : What are the power requirements?
  Answer : It is battery powered.
• Question : What is the size of the sensor?
  Answer : It measures 1.38 inches.
• Question : Can this be installed outdoors under a wide overhang?

• Question : Did aeotec blindly google "convert 0.4 celsius to fahrenheit" and put it on the box or is the fahrenheit accuracy really plus/minus 32.72 degrees?
  Answer : The device registers one significant digit behind the decimal. The Fahrenheit accuracy is not plus/minus 32.72 degrees.
• Question : Can I hardwire this sensor? Is there USB power in?
  Answer : If you are skilled with fabrication and small electronics, you can connect an external power supply. Soldering would be required. However, there is no externally accessible USB port.
• Question : Does this work with Abode that supports Z-wave plus?
  Answer : It paired with my Homeseer Z-wave plus system without any issues. I am not sure about Abode compatibility.
• Question : One place in the item description claims it can read down to 14°F, yet in another place the lower end of its range is 0°C. So which is it?
  Answer : The device contains two sensors with the following accuracy measures: Relative Humidity - precision +/- 3% RH (max), range 0 to 80% RH | Temperature - precision +/- 0.4°C (max), range 0 to 65°C
• Question : Does this work with a SmartThings 2nd Gen hub?
  Answer : Yes, I have successfully used this with a Smart Things v2 hub.
• Question : Will the temp sensor function below 0°C/32°F? Will it malfunction or just unable to measure and report below that?
  Answer : The lowest temperature seen so far is 35 degrees Fahrenheit, and it worked fine at that level.
• Question : Will this work with Ring?
  Answer : I use it through my Z-wave Hubitat network. I am not sure if you can use it in a Ring network.
