One of the nerdy features of CARROT Weather I love is its support for personal weather stations as a data source. Not long ago, Federico explained on AppStories that the weather station down the street from him had shut down, so he could no longer use it as a source in CARROT. I suggested he get a Netatmo Personal Weather Station and connect it to Weather Underground’s network of stations, but at about the same time Weather Underground ended its support for the Netatmo device, which left us both without a hyper-local weather source. It wasn’t a huge deal, but there’s something fun about knowing that the temperature you’re seeing in CARROT is the precise temperature outside your window and not some weather station that may be miles away from your home.

With today’s update, CARROT has stepped in with direct support for the Netatmo weather station as well as other new data sources. For the Netatmo device, all you need to do is sign in using the same login you use for Netatmo’s dedicated app, and as long as you’re within two miles of your home, CARROT will include the data collected by the Netatmo device.

Dark Sky is the default data source for CARROT, but users have three other options. The first is The Weather Channel, which provides the most extended-range forecast (data covering the next 360 hours and 15 days), is available worldwide, and can access personal weather stations connected to the Weather Underground network. CARROT has also added AccuWeather and AerisWeather as data sources. The AerisWeather option includes PWSweather.com personal weather station data. Users have the option of including Dark Sky’s short-term precipitation in CARROT even if The Weather Channel, AccuWeather, or AerisWeather is their data source.

Personal weather stations connected to the Weather Underground system and PWSweather.com can be selected from a map allowing you to pick one closest to where you live. Other than the personal weather station access through the Weather Channel’s API though, Weather Underground data, which was previously a data source option in CARROT, has been removed because IBM, which owns Weather Underground, has discontinued its API.

CARROT Weather’s update includes a host of other smaller additions too:

• Air quality index and pollen data are available in the current weather view if you use The Weather Channel or AccuWeather as sources
• There are six new secret locations to discover
• The location screen has a new ‘Recent Searches’ section, from which you can add previous searches to your saved locations by tapping the star icon next to them.

I’m glad Brian Mueller has expanded the data source options for CARROT Weather. The best source varies depending on where you are, and with more sources, CARROT should be a better option for more users going forward. I especially like the personal weather station integration. Whether you have a weather sensor yourself or want to piggy-back on another publicly-available station nearby, they’re an excellent way to track hyper-local conditions.

CARROT Weather is available as a free update to existing users on the App Store.
