How do the outdoor sensors handle extreme heat?

I live in the Las Vegas area and summer outdoor air temps can reach 117F in the shade, even hotter in full sun. Do the outdoor devices handle this okay? I guess there are plenty of devices in the area shown on the map but I just want to be sure I’m not going to have issues - maybe premature failure of sensors or other electronics in the device?

I built an “umbrella” out of an inverted black plastic nursery pot to keep the direct sun off of my Zen. The pot rim is even with the lower edge of the unit and the pot is otherwise a couple of inches away from the Zen at all points. The whole assembly is mounted near the top of a 12’ pole along with my Weatherflow Tempest and the pole is mounted about 50" in back of my house. I painted the pot and pole a sandy color to blend into the background. Everything seems to work well so far.
