The Ambient Weather skill provides Ambient Weather personal weather station owners with the ability to get real-time, and past weather information generated by the devices they have set up at AmbientWeather.net.
To get started: say "OK Google, talk to Ambient Weather" to invoke the Ambient Weather app. Or, say "Ask Ambient Weather to give me a report" in order to get a detailed recap of the current temperature. Once the Ambient Weather app is initiated, you can use commands like "Give me a weather report." or "What are the current conditions". Both of these commands (along with a many others) will provide you with your outdoor weather report.
You can also ask for your indoor weather report as well by invoking the Ambient Weather app in the same way, then saying, "what are the indoor conditions?", or "What's it like inside?" You can also ask for a report about a specific day, month or year! Just say "Give me a report for June 14th", "What was the weather yesterday?", or "What was the weather in May?"
Just remember, before giving your Google Home device any commands, initialize the app by saying "OK Google, talk to Ambient Weather".
