Thank you Tom, I didn't mention that I purchased 2 Tempests of which 3 (yes, three of two, because the replacements sent by weatherflow were also defective) were defective with distinct issues within less than half a year. So, no, not again.
For the Vantage Pro: for me it seems that more recent versions have detachable rain buckets and one could locate the humitemp inside a "sensor hut" and the rain bucket on top of the hut with a cabled connection to the solar powered, battery backed transmitter. A second, solar powered battery backed transmitter could be mounted on the mast on the roof top with the cabled anemometer and uv/radiation sensors attached to it. I would even tune this transmitter box with a solar powered LTO battery (lithium titanat) instead of the CR123, in theory, this would run "forever", a LTO can stand 10k+ cycles and still has 50% of it's rated capacity and discharge capabilities down to -20°C (That's one of the good things in the Tempest, they use an LTO also, but 1300mA is too small for locations near the arctic circle obviously) Anyway, it is nearly impossible to get your hands on a recent VP2, at least, where I live. So any input of a user with a more recent revision would be very interesting. Tom Hogland schrieb am Dienstag, 28.
