Cumulus Support

Is it possible to have a parameter that allows you to round output to a number of decimal places (including none) for tags that generate numeric output?

Looks like it is possible

Yes, I've seen that. But it only works for certain tags - hence the request for it to be extended to all numeric tags.

Whoops, I should have read the title Cumulus MX Development Suggestions

I'll take a look, but with over 700 tags it sounds like a lot of typing may be involved! So it maybe a back burner one for now.

Sounds like an ideal candidate for an abstract parent class that the tags can inherit from - if tags are modelled using classes. I'm happy to do it - it's my bread and butter

You'd wish!
v4 is very different (if we ever see it), but no, v3 is a function per tag.

Yes, I can see that now.

I've made the changes in a local copy of MX and they are running on my website https://www.hosiene.co.uk/weather/

I have only changed #wlatest, #wspeed and #wgust, as they are the ones I was interested in. Happy to do more, though - but it is really the wind speed ones I am interested in. I like the single decimal point for averages, but for instantaneous values I prefer rounded numbers.

Currently in MX you either have all rounded or all to 1 dp.

Let me know if you are interested in the changes and I will give them to you.

Now, should they be rounded or truncated to integers, the latter I think.

And, yes I use 1dp for wind average, and the integer value for latest, gust - as supplied by the VP2

Definitely rounded. 24.9 knots is more 25 knots than 24
Latest gust converted to knots ends up a non-integer.

Implemented - you can now also set the decimals globally via the station settings page.

Awesome, thanks Mark. In my custom MX builds I have been using (for example):
This will work now with the build untouched?

Also, for zero decimal places, are values rounded or truncated?

It is implemented globally rather than per tag. So you can set the number of dp for wind speed (current, gust), wind run, and wind average independently of each other in the settings.
All other units also have their own dp settings.

Hmm nice touch! though I thought Mark you only worked in Binary.

either the value of 1 or 0 would suffice

Okay, so that looks as if it will be storing in whatever precision you pick in the settings. So if you pick speed as 0 decimal places then it will be stored that way?
