I was searching for a low end weather station with multiple sensors included. The only viable option available immediately was this gadget.
DFA Dostmann Wireless Weather Station VIEW
It has three transmitters out of the box which is one more that I was shopping for. A bonus.
Let's unbox this box.
-40 degrees low limit is nice too, by the way.
Everything is nicely wrapped.
The main box, still with a sticker on the display, with one transmitter.
Before the batteries went in, two AAAs.
Sensors are using a pair of AAA batteries too. All together you will need eight of them.
Everything connected and working. You press a sync button at the back and the connections are made quite quickly.
You can see that the main unit and the sensors are in a slight disagreement.
Today, in the evening, with the three sensors outdoors and together the measurements were ...
Just 0.1 degree off and with humidity readings from 50 to 58%, I would call it decent.
In this price range, 50 €, you don't expect lab precision anyways.
OK, so far so good. The real test will be on the road. The station will be used in our RV with sensors attached at various locations. Both hot - gas oven, and cold - outside at the bottom of the chassis.
Stay tuned for real-life usage and measurements.
Oh, the watch didn't radio-sync. It was set manually.
By the way, the gadget sports usual functions - weather prediction based on air pressure, min and max values, nothing really needed. Maybe min values during the night are useful in the winter time.
Better and better

Seems to be useful for you. I wonder how long will the batteries last inside the sensors. I got two AA ones in my weather station too for backup power but it also has a solar array and for 2 years I havent had to change batteres.
I will install them today and we'll see :)
With the cold that we have now, -10 during most nights, they won't last very long.
Yes, solar panels are a must. We have two panels, 400 W together, on our RV and don't need to extra charge the batteries at all, winter cold included.

I have a cheaper one at home. Useful stuff.
It's probably the same price + two additional sensors.

I paid around 30. But it shows less data than yours, just the necessities.

Never though that this is a thing. I would like to see how you will use this when we have weather apps available everywhere.
:) I don' need to know what phone app tells me about the temperature in a vaguely surrounding area. I need to know how cold or hot it is a couple of meters away from me and from this weather station.
For example, water reservoir of the gas boiler self-opens when temperature drops under 4 degrees and water runs out and we are out of water for the long weekend outdoors. Simple as that.
Or, the built-in sensor tells me something yet I know it's wrong. Now I have a way to prove it wrong :)
By the way, the transmitter reach is 60 meters, decent.
Okay. Makes sense. I hope it helps you automate your system. I like the gadget.
I hope I'll like it too.
