How to install outdoor sensors:
Note: In order to receive real temperature values, you should avoid installing sensors directly in the sun. We recommend placing the remote sensor on an outdoor wall facing north. Before installing it on the wall, place a screw with a 5 mm screw head and install the outdoor sensor on the screw.
The electronic part of the outdoor sensor has a layer of moisture-proof synthetic resin to protect the circuit. However, the sensor is not waterproof, so direct rain should be avoided
