Weather forecast
This skill implementation follows steps explained on the intro page to provide weather information for a spoken city. This skill requires an active internet connection to access a weather API. Openweathermap’s API was the first API found on google while searching for weather API’s. It is easy to access and provides all information needed to implement this skill. The only thing required is a registration to obtain an API key.
- Get weather information (temperature, humidity and weather details)
- Get weather forecast for the next 5 days
- Get sunset / sunrise information
Add slots
This skill requires a slot list named city. After creating the slot list add your desired cities to it. Download a list containing 14000 german cities here.
Add intents
[GetWeatherInfo]
(wie | sag mir) [ist] das wetter in $city{city}
[GetWeeklyWeatherInfo]
(was | wie | sag mir) [ist] das wetter für [die] (kommende | nächste) woche in $city{city}
[GetSunriseInfo]
(wann | um wie viel uhr) geht [die] sonne in $city{city} auf
[GetSunsetInfo]
(wann | um wie viel uhr) geht [die] sonne in $city{city} unter
Training might take a while depending on your Pi’s hardware. If training fails, try adding the sentences one by one. After training click View and then Confirm Guesses to accept pronunciation for unknown words.
Example sentences
1. wie ist das wetter in gummersbach (how is the weather in gummersbach)
2. wie ist das wetter für die kommende woche in berlin (how is the weather for the coming week in berlin)
3. wann geht die sonne in hamburg auf (whe does the sun set in hamburg)
Node-RED flow creation
Openweathermap provides its own custom Node-RED node. The node can be downloaded by accessing Node-RED’s header menu an clicking on manage palette , search for openweathermap and press install. A API key input is required for every openweathermap node added to the flow.
The web socket in node waits for an intent to be spoken. After an intent is recognized the json structured payload is checked for a city object. The city object is mapped to a location object and a country object is added. All the information is then passed to the check intent switch. This switch passes the information to the next node depending on the intent name associated with the spoken intent. The 5 day weather forecast requires location coordinates which are retrieved using the http request node named request to api to get coordinates. The function nodes contain javascript code, responsible for extracting weather information obtained from Openweathermap’s API. The weather information is then passed to Rhasspy’s text to speech API.
Download the json file associated with this flow and import it into Node-RED using the header menu to get a deeper look into this skill.
