code a 'Rainsensor ' for my garden sprinkler

Hi there,
summer is coming soon and it`s time to make some thoughts about a green garden.
As I don`t want to spent a lot of money in a hardware watersensor, I solved it with blocky.
Have fun:

I devided the sensor in two parts:
1) When was the last rainy day?
2) Do I have to activate the garden sprinkler

Here`s the 1)

Its simple explained: Pulse-station checks the Weather-ID every 15 minutes and ifs not a “sunny” ID, I write the variables ($weatherID) and ($LastRainDay)

Here`s the 2)

In the morning and the evening I check the temparature. If it`s to cold (<22) I set my virtual binary switch “Sonnentag” to “false”
If it`s hotter, then I check when there was the last rainy day. If it was yesterday or a date before I set my Sonnentag” to “true”

Finally I put 1) and 2) in one scene and voila: A cheap solution for a rainsensor.
