Hi all,
after nearly 2 weeks of reading, fixing, reading and fixing again, I want to try my luck here…
After a lot (I really mean A LOT) of troubleshooting, I finally wanted to create my own heating automation for my Aqara E1 TRVs. I managed to create a blueprint that creates an automation. However, I cannot get this automation to run.
My troubleshooting so far makes me believe, that something is wrong with the use of variables in my blueprint. If I create an automation with this blueprint, and I test the if conditions, all of them using variables seem to fail. But whatever I try, I cannot get it to work. I read so lot about blueprints, triggers, actions, inputs, variables and so on, but I have to admit that I have now reached the end of my knowledge.
I really hope someone can point me in the right direction… even ChatGPT and Gemini gave up already 
…
This is my blueprint so far:
