Min / Max temps being missed
As the title suggests, I've noticed that some of the min and max temps for the day are 0.1 or 0.2°C different. It doesn't happen every day, though. I thought it might have been the °C to °F conversion thing, but I checked my console, and it has the correct values (comparing them to weatherlink live)

Re: Min / Max temps being missed
The ISS updates the temperature every 10 seconds, MX polls the WLL every 30 seconds, so it is possible that the odd high/low could be missed.
The station does not provide highs and lows, nor does wl.com other than for each archived data interval, so MX relies on capturing the live data, I guess I could reduce the poll interval for temperature to 10 seconds.

Re: Min / Max temps being missed
Ah I see. I thought the highs/lows were provided by the API..
You'd think Davis would provide that, as it seems the easiest way to grab them?

Re: Min / Max temps being missed
They have moved to this model of the APIs providing actual data and not summary/derived data 
The WLL obviously keeps track of highs/lows internally as it only sends data to wl.com once a minute, shame it does not make that data available to users!
I have posted a query to Davis to see if they have any suggestions.
