@sdetweil from my very basic understanding of how it was developed, i think it was stored it as a string so that it could be concatenated? again, this is based on 5 minutes of Google-fu and no understanding of JS here
-
@jolt02 js will convert in either direction automatically, except if u ask, is this a number or a string
temp: 1234 is a number
temp ‘1234’ is a string
temp: ‘null’ is string
temp: null is undefinedprint temp from above will do 1234, or 1234, or null, or undefined

@jolt02 All these weather sites use data from private weather enthusiasts that have varying equipment so the accuracy will never be 100% spot on. Im using data from a Bassendean site which is in the proximity of my place. It is “close” but as there is no official BOM reading for the area, who is to say its wrong. BOM get there Temps for ‘Perth’ from their site at the airport and in the city,
I find a lot of the “Pro” sites like weather channel, Google etc are using data from sites in the northern Hemisphere. This can make it very hard to know what is the correct temp. I have an API from BOM but haven’t figured out the coding as they don;t use Json.
I would like to get data from Windy.com for cloud and wave data but that is expensive
-
@harney thats a pitty the BOM doesnt have close data for your site.
I have found that all the regular weather providers (Open weather, darksky etc) forecasts and observations are less than adequate for Oz.So I have been reworking the Weather Module from WallberryTheme to use Aus govs BOM data. getting observations was easier enough as they provide that in JSON format which makes it some what easy but they only provide XML data for forecasts and the format is different for every site :( so my plans to “release” my module have stalled. because it has to be customised for each site.
-
@saabman yep. I have found the xml to be a problem and out of my range of knowledge. OpenWeather is close to accurate for my location for current conditions,. the particular site location uses excellent monitoring equipment, just a few degrees out, but for forecasting its not that accurate.
-
@harney use a lib to convert to json…
google search
nodejs xml to json
there are a few…
some let you target a specific section of the xml -
@sdetweil said in MMM-MyWeather not working with Southern Hemisphere co-ordinates:
nodejs xml to json
Thanks Sam, I will see what i can do

yes the XML issue was a problem but I got around that by downloading the XML then as sdetweil suggested using XLM2JS to convert the file to JSON which I could ten search for the relevant fields unfortunately its not very tidy and needs customizing for each site.
IF you want to have a look at how Ive done it the files are here
https://github.com/saabman/WallberryTheme/blob/master/WB-weather/README.mdI am not by any means a programmer - just kept hacking away at the weather module till it did what I wanted - Im sure there are better ways to do it… hopefully it is help full any way

Unfortunately BOM lately has made changes to their site which is preventing accessing their data claiming it’s scraping but they provide a JSON file which I’m accessing (for part of it anyway) so my module no longer works- I’ve changed things a couple of times to circumvent the issue but it keeps coming back so I’m going to look at other ways to access the data. One that looks promising is WillyWeather. It is a paid service based on the number of access’s billed monthly. But it appears to be very cheap - It looks like for one Magic Mirror accessing data from one weather station and radar image works out at less than $10 a year.
When accessing the BOM currently they return a message to fill in a request form and some one will make contact - I filled in their form a couple of months ago and am yet to receive a response. Maybe when they get the servers sorted out things might change….
