that’ll work, fyi always post logs when something doesn’t work. Saying “doesn’t work” is the least helpful comment to a person helping you.

Ok, does states(‘input_text.crypto_name’) have text in it?

24

Yes

crypto_name:
  name: "Crypto name"
  max: 10
  initial: 1inch

I add a initial so it have always a text

Then those errors should only be there on startup but after the actual state is received it should work

Everything is working now.
Even I add 220 sensors for each crypto. HA doesn’t care about that amount.
The REST Sensor have a timeout for 30 seconds so it won’t stop whole restart HA.
All template sensors are loading correct without timeout errors in the log.

Now search for a way to select them and show them in Lovelace. Want a 3 columns with 3 rows each.
thought about input_text entities where I enter the crypto name and them it will show up or something.
