IF I were living where you are, I would go with the 24 hr. FARS. You generally have hot days and cool nights, The daytime unit only works when there is sun on the solar panel. At night , if it is a muggy one, you want to get the air moving across the sensor. I would go for the 24 hr. And with it go with the VP2 Plus, that comes with the solar radiation and UV sensor to complete the unit . more expensive but valuable.
I have a VP2Plus FARS. Wireless and solar/UV sensors... soil moisture/temperature sensors. A lot of good information on how things are above the ground and below.
