And according to units.py the observation type wetbulb temperature is
called outWetbulb and not wetbulb_t.
Consider that in MQTT output the underscore is used to separate the
observation type name from the unit name.

If you followed the directions at the top of your file, you're almost
there. Now you need to make sure your new type is put in the archive
record. Do this by adding it to the list of types under [StdWXCalculate]:

# How to calculate derived quantities.
Hello everyone
I have implemented the wetbulp.py file in my weewx. But now I have noticed
that after creating the column in the database, the value is not saved.
Could it be that this line is missing in "wetbulb.py"? If so, what would it
have to look like for it to work?
Thx

thank you, i will do this in database.

Yes, that will be it. Loading and calculating for a day will be
straightforward, though it will involve a lot of complex calculations being
done each time you call the aggregate (and this will occur each time you
run the report, so potentially every archive interval minutes). On the
other
Calculating aggregates for non-linear functions is not easy. For example,
it's not obvious which combinations of temperature and humidity will result
in the lowest wet bulb temperature for the day. It can be done by taking
partial derivates of temperature and humidity, setting to zero, then
No, i just adjustet the vaporpressure.py example.
But i see what you mean, i have to calculate it by my own, this means i
have to load all data for a day and calculate it.
im not shure i can do this.
i quess its easyer and better to do this in the database.

Hi,
When you wrote your xtype extension what methods did you implement? Did you
implement get_aggregate()?
