Do's and Don'ts:

• Do take it apart :D!
• Do design your own housing.
• Do Create custom lighting effects.
• Do adjust your ventilation system with the sensor values.
• Don't place the sensor in direct sunlight.
• Don't place the sensor outside.
• Don't place the sensor in an area with high humidity.
• Don't place the sensor in a windy area, this will influence the temperature and RH calibration.

Keep in mind If the sensor comes pre-programmed to either be Wi-Fi or Ethernet you need to reprogram the sensor to be able to use the other connectivity option. So if you order with Ethernet preprogrammed in and you want to use Wi-Fi you need to reprogram it using ESPHOME.
