How to use intermediate variables to adjust heating schedule

As someone with such extensive experience you should understand how important semantics are. Persisting with incorrect terminology, when you’ve been afforded some grace, is just stubborn, and now you’re blaming the (incredibly knowledgeable) people that tried to help. Your initial post was confusing and lacked vital information.

The entity domain is a vital concept in HA to understand. A sensor is by definition not something you can change directly, because it’s supposed to (roughly speaking) be a measurement of something. You change the speed of your car via the accelerator pedal, not by moving the dial with your finger. If you keep using incorrect terminology, it will be hard to know if you understand what you’ve been told and will just further confuse those trying to help.

There is also no concept of a variable in the sense you’re trying to use it (HA scripts and automations do have them, but it serves a specific purpose). Those variables you have are specific to a 3rd party component: the custom button card. Its value only exists within the scope of the card. With 50 years experience I would expect you to understand what scope means. You can change the variable within that scope, but it will have no bearing on anything else. Either you have actuating entities like a switch, one of the helper entities or such, or you call services/use actions to affect something.

I read through everything again and you really got all the answers. It’s up to you to invest the time to understand what you’ve been told.

Prove it.

What’s comical is that it is possible. As I stated above. It’s just not possible with a sensor.

You’ve just been to stubborn to see the answer.

If you want explicit help getting this done, ask away. Just be prepared to provide requested information instead of being combative. It took me 10 pain staking posts to get the full picture of what you’re trying to do because your original post wasn’t clear enough.

Have you even read my post?

Your comments and reaction REALLY come across as defiant and absolute. I am unsure if you realize the folks assisting here sacrifice their free time on this forum. There is roughly 50-70 consistent folks who volunteer with no pay to provide support for the 300,060 members.

If I were you, I’d take a step back , isolate the major contributors and honestly take a look at how much we contribute, I consider myself a smart guy(jack of all trades), but I was quick to check my ego at the door when I joined the forum.

As a rule, you will always encounter someone that is smarter than yourself. Without humility, a person will never reach their full potential. You have to embrace a lifetime of listening and learning from other… Best of Luck
