Hello,
I was able to set up a meteobridge Pro 2 device in parallel with the davis console (Vantage Pro 2)

Meteobridge works via RF mode (direct signal reception).

I noticed that the maximum gust recorded by the davis console (so read every 2.5 seconds) today is 16.1 km/h, however in meteobridge I don't have the same value and the maximum comes out as 13.3 km/h.

Is this difference due to the fact that meteobridge does not read with the same measurement frequency the gusts? Is there any way to fix this?

Similar discourse for the maximum temperature measured: in Davis 32.7°C, from meteobridge 32.6°C.

Second question:
Reception between Meteobridge and ISS Davis is averaging -76db (fluctuations detected between -72 and -82 with threshold set at -85). Does this sound like a good result?

Thanks

When comparing daily maximums first you should make sure that both are on same time and timezone. Otherwise you compare different ranges of data.

Meteobridge records all wind information it can get via RF. If there is a RF drop of the highest wind gust spike Meteobridge will not have it and can't take it into account. Same with Davis Console, while it has a better reception rate and therefore might have fewer misses.

Did you use "wind0wind-dmax" to receive maximum gust of the day? Or how did you compare values?
