Hi Henrik. I think you have this set up correctly, but there's a step missing which is to load the values of the IFTTT parameters into your SEQUEmatic variables. Let me step through an example.
In IFTTT, create your applet. In this example I'm using Weather Underground as the IF THIS or trigger, set to run each day at 8pm. The THEN THAT or action is to make a webhook request.
The URL I call in the webhook request has come from the SEQUEmatic trigger step, but I've added the parameters on the end. They're enclosed in double curly brackets {{ }} because they're referring to IFTTT ingredients.
http://sequematic.com/trigger-ifttt-webhook/mykey/12345/weather/ {{CurrentCondition}}/ {{HighTempCelsius}}/ {{LowTempCelsius}}
Here's a screenshot of the full applet if you need more information.
I think you probably already have that set up correctly. The tricky part now is in how you pass the values from the IFTTT parameters to SEQUEmatic.
Your sequence should start with the IFTTT webhook trigger, which you already have. In this step, you will need to tell SEQUEmatic the names of the parameters. See the screenshot below for the values I have used. These match with the position IFTTT passes its ingredients in the webhook URL used above. You will need these parameter names further down to load the values into SEQUEmatic variables.
Now, before you can do anything with these values, you will need to store them in a variable. To do this, add a change variable step and enter the name of the variable that will store the value. In your case, this is Wcondition. Then, in the value field enter the parameter name you used in the trigger step, enclosed in curly brackets - for example {condition} which I used to pass the weather condition.
You should add a step for each parameter you wish to store. Here's an example of what these steps will look like.
Once you have the parameters loaded into your variables, you can then use the variables as usual.
I've taken a look at your Sunrise sequence. You should add a change variable step in between the IFTTT webhook and your Wcondition IF statement to store the weather condition parameter in Wcondition. Then, your Wcondition condition should work fine.
Let me know if you have any questions setting this up.
