Meanwhile, I have three weather stations with 433 MHz wireless technologies behind me. All have failed to link problems to the outdoor sensor from the attic to the first floor (approximately 6-7 meters in a straight line). The connection was from the outset weak (intermittent failure of the outdoor temperature display) and had all failed after a few months. Relocation of the sensor to about 2-3m at the station had also brought nothing. Therefore, I had put on the new 866 MHz technology (100m instead of 25-30m range) when purchasing a new weather station. The device should also look appealing and indoor display / outdoor temperature, humidity and weather tendency. So I have become aware of the TFA weather station Weather-Girl-XS. She has a clearly structured display and shows besides the expected of me sizes even date (optional date + year, weekday + date or seconds), sunrise, sunset or sunshine duration (also each selectable), the current moon phase and minimum / maximum values for temperature and humidity on. In addition, they can serve as an alarm clock (alarm), but now I absolutely do not need. Despite the complexity of the device can be quite easy to use, the manual but you should read it anyway. The accuracy is very good, for example, it indicates 40% humidity, my very old analog hygrometer 43 (the latter might probably inaccurate). Indoor and outdoor temperature are almost identical with a mercury thermometer outside and another digital outdoor thermometer that despite 433 MHz is still working (distance from the outer sensor 50 cm) even with +/- 0.2 degrees deviation. On the device there is to complain about little. The black plastic case with silver frame around the display seems not really high, but is meticulously crafted. Weather girl just shows the current temperature in five areas of the weather trend is limited to three stages' of other weather stations show a tendency in 4-5 stages to. The inscription is completely English (funny on the frame around the display is TFA / Germany), but since we have perforce get used to us, right? What is missing is a better visual presentation to market the high-quality technology far more expensive. So for you!
