Hi @Erik erik, I have a flow that turns on the sprinkler. As a condition I want to set that it only switches on when the rain forecast (rainTo) from the weather service is 0 and the weather (description) is "Wolkenlos) . Furthermore it should switch on either 5 or 10 minutes, depending on the weather forecast, if sunny then 10 minutes, if cloudy only 5 minutes. Then I would be able to do it myself, but I need the values rain ($.forecasts[0].rainTo) and weather forecast ($.forecasts[0].symbol.description) as conditions, he should get these values with the JSON query from the weather service: [http://daten.buergernetz.bz.it/services/weather/district/6/bulletin?format=json&lang=de](http://daten.buergernetz.bz.it/services/weather/district/6/bulletin?format=json&lang=de) This are may flows: [https://homey.app/f/v69lv7](https://homey.app/f/v69lv7) [https://homey.app/f/idflv7](https://homey.app/f/idflv7) [https://homey.app/f/cVhlv7](https://homey.app/f/cVhlv7) Thanks a lot Philipp ---

Hello @Erik, could you help me to solve the flow with HTTP get an the Homey Logik Variables? Simple if the value extraxted from the JSON Url is corrisponding to a specific text (like “wolkig”), then set a homey Logic Variable to YES/NO. thanks Thanks [Previous page](https://community.homey.app/t/calling-an-external-service-and-receiving-the-response-in-a-variable/12445.md?page=2)
