Every entity’s state property can only hold a maximum of 255 characters. Sometimes your REST Sensor’s template produces a value that exceeds the limit.

Ensure your template never produces a string whose length exceeds 255 characters.

If you must store a longer value, then you’ll have use attributes, not state, because it can hold about 16K.

I also see that.
The comment says every hour, but I would bet the 30 & 60 are actually seconds. Only mention in case you think that is minutes.

Also the problem you list

shows that this is looking every minute. I would suggest a longer time if your needs can allow it.

That is nice to know, thank you.
This is my code now that works without every 2 minutes the attributes disapear
The only thing that i can’t seem to grasp is how you set a state in the rest sensor and have a way to display attributes aswell
