This probe is solar energy and with a rechargeable battery by the sun which is also supplied. Data transmitted to the weather station are fair and correct. Do not forget to press the reset or battery change as soon as you remove the battery to be sure the station detects the probe. It is hung by a screw against a wall that separates it from the station and the transmission is fine. Make sure the power to the main station is very good for proper data reception. The probe has a light that indicates normally when the battery is charged. Personally, I have never managed to light the lamp. This does not prevent run correctly.
