Yaml script in HA but no activation

[peterverbogt80]

Hello everyone,

I’m Peter from the Netherlands. Like many others, I’m trying to control all the major energy consumers in our house—especially heating—so I can activate them when energy prices are lowest or when solar power is available. To start, I’m focusing on controlling the electric heating in our garage.
Since I’m not a programmer, I asked ChatGPT and Mistral to help me create a script. While it looks good, it doesn’t work as intended. First, the heating doesn’t start automatically. And when I turn it on manually, it doesn’t turn off automatically either.
I’ve checked all the sensors, and they’re working correctly. I apologize for the YAML code containing many symbols; I added them to make it more readable for myself.
Project Overview:
I have a Shelly 1 Mini connected to the plus and minus terminals of the normal thermostat input on the electric heater. The Shelly 1 Mini is controlled by Home Assistant (HA) using the script below.
The heating can activate in two ways:

Solar power mode: It turns on when net solar output exceeds 2000 watts and turns off when it drops below 400 watts.
Winter mode: If the remote thermostat drops below 10°C, the heating starts during the cheapest hourly energy prices of the day and turns off once 11°C is reached.
I also have an override switch to turn the heating on immediately and a season switch to disable heating in summer.
Errors:
The following lines in the script generate a PatternWarning:

service: switch.turn_on
service: switch.turn_off
platform: numeric_state
platform: state
These are the only errors I can see in the Home Assistant Code Studio.

Troubleshooting Steps:
Initially, Home Assistant showed the garage heating status as "waiting on temperature." I asked Mistral (Euro Chat GTP) to fix the issue, and it made some changes to the script. However, it feels like relying on AI to get this right is a dead end. Maybe I’m not asking the right questions or providing the right input, but I hope someone here can spot why the script isn’t working.
(Note: Most of the additional text in the script is in Dutch.)

It would help me a lot if this one was working so I can use this at a base line of the heating in our house and the warm water supply.
Thank you in advance!
