My motorhome weather station installation


I've had various home weather stations for > 25 years, and been putting them on the internet for almost that long.

I put a lot of thought into what I wanted on my motorhome, and the mounting and location limitations. I was actually designing one around an Arduino and some separate non-moving sensors rather than use a model with mechanical wind and rain sensors, which would not work well on the roof, in motion.

Before I started buying parts, a friend introduced me to the WeatherFlow Tempest. I'd been skeptical of these and others like NetAtmos. But the price point was good enough (less than the stand alone ultrasonic wind sensor I was looking at), so I bought one.

For testing, I installed it on the same pole as my preferred Davis Vantage Pro 2 Plus out in the yard. The 2 tracked each other pretty well over the last 2 months, only disagreeing occasionally on total rainfall.

So I fabbed up a mounting plate from 3/8" HDPE boat board. Yesterday I mounted the station on the top eyebrow, and the hub in the tech cabinet and connected to to the RV wifi.

Overall, the station is ~9" tall, which is shorter than the TV antenna, Dish dish, or the A/C.

One of the reasons I wanted one is to have an idea of the wind and direction when parked. I set the station with North pointed forward. and set the display to degrees rather than cardinal NEWS. Even when I'm driving, it should show the vector sum the wind of the direction of travel plus the head/cross/or tail wind velocity and direction. Moving or parked, I'm more interested in wind direction compared to how I'm parked, rather than the "map" direction.

The Tempest also has a lightning detector chip in it, which is more useful than I thought it would be, and compares well to other lighting sensors i have.

We're going on 6 hour out and back trip Friday to a craft market, so it should be a good shake-down cruise for the Tempest.

When I Drag Raced I carried My Davis Pro-2 w/rain collector and used a pole to install it on my Race trailer. It was Wired-Plug and play into my MH with the phone cord and plug-always worked perfect. After i quit racing i sent it to Davis and had it converted to Wireless. It's now in my Back Yard about 120 ft away and my Console is in my office, works great.
But I like your setup !
