Ariston Gas Cylinder Estimations

Configuration
1

Hi HA enthusiasts, :slight_smile:

I’m new to this and I’m trying to setup a config so I can estimate the remaining of propane in the cylinder and act accordingly with some automation.

I have tried chatGPT but is seems it lack a deep understanding of this platform.

Can you give me some feedback on this config.
What could work what can be improved?

Thank you!
