- Indoor (Master) unit
Outdoor (slave) unit which monitors temperature
Outdoor rain sensor
Outdoor wind sensor
The rain and wind sensors need to be due to their purposes in fairly exposed areas, however the temperature sensor should not be in direct sunlight so as to avoid it actually heating up rather than measuring background temperature. In reality based on the often erroneous temperatures reported by various peoples Netatmo weather systems according to the Weather Wunderground site it is clear many people are leaving the outdoor temperature unit in direct sunlight. This has given the Netatmo solution an unfairly bad reputation for poor accuracy.
'Real' weather stations to prevent this have the temperature sensor located inside what is known as a Stevenson Screen - https://en.wikipedia.org/wiki/Stevenson_screen . This screen prevents direct sunlight causing false temperature readings. The current Netatmo sensor is obviously not protected by a Stevenson Screen hence the problem. It should be noted that even many smart home weather stations also use Stevenson Screens for the same reason.
My request therefore is that either Netatmo come up with an addon which adds a Stevenson Screen to the existing unit whilst maintaining a means of mounting it, or releases a new improved unit which has a built-in Stevenson Screen.
Consideration should also be given to taking the opportunity for including other sensors or improved sensors e.g. humidity, UV, hours of sunlight, etc. etc.
