Mounting VMBMETEO

English
1

I’m planning to buy VMBMETEO soon and I have a problem how to mount it. Obviously the manual shows how to fix it to wall/roof, but:

  1. It should be exposed to rain
  2. It should be exposed to wind
  3. It should be hidden from direct sunlight or the temperature measurement will be useless

Point 3 seems to contradict 1 and 2. Any ideas or photos of actual installations that work nicely?

P.S. My current outdoor thermometer is annoying and I plan to use VMBMETEO + probably a small OLED screen controlled by openHAB to replace it.

I’m somewhat skeptical of accuracy of wind speed or rain measurements if the station is mounted on anything but a pole with no obstructions in any direction. Wall mounting would definitely reduce the measured wind in certain directions, for example, and if it is windy during rain – it might underestimate the amount of rain too.

A naive solution would be to install a temperature measurement device on the north-facing wall (provided you’re based in the northern hemisphere) as a separate device and ignore whatever VMBMETEO ends up measuring in terms of temperature. VMBPIRO, for example, can serve as a temperature sensor as well.

I also had considered VMBMETEO, but in the end ended up with two VMBPIROs for temperature, light and motion sensing, an AirGradient for air quality measurements and a generic hall effect rain gauge for my rain sensing needs (I have no need for a wind sensor.) Combining this all together into an useful system requires some DIY though and any integration goes through outside Velbus, so that’s the downside…

(EDIT: “real” meteorological stations use a sun shield that usually looks like this:

Excellent suggestions.

Don’t forget that you can always pull sensor data into Velbus by using the VMB4AN or (soon) the VMB8IN (and more options to follow, depending on potential sales)

Thank you!!! :heart_eyes: VMBPIROs will be my main outdoor temperature sensor - somehow I did not think about it :blush: The VMBMETEO will be mounted on the roof, on a short antenna mast, on the corner of the building.
