Generic thermostat climate control with physical buttons

Configuration
1

I am trying to build a custom hot tub controller using the generic thermostat card to control the temp but need some help with controlling the temperature setting up or down with a physical button. I had it working then had some problems with my tasmota D1 mini and now it doesn’t work. I found this online and adapted it but now it is not working. Not sure what happened but if you have any help I would greatly appreciate it. I have double checked everything but cant figure out what is wrong. I am not very good with this and have had a lot of problems trying to figure out indentions and format in general.

# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

# Text to speech

        - service: climate.set_temperature
    data_template:
        entity_id: climate.spa_heater
        temperature: "{{(state_attr('climate.spa_heater' , 'temperature')|round(0)) + 1 }}"
        
    heat_down:
        alias: heat_down
        sequence:

        entity_id: climate.spa_heater
        temperature: "{{(state_attr('climate.spa_heater' , 'temperature')|round(0)) - 1 }}"

Sorry should have mentioned I call service “heat_up” script or down in the basic automations of home assistant when the button is pushed.

Me thinks that it’s an indentation issue - here’s my script to compare:

script:
  a_c_l_e_one_up:
    alias: A/C L&E One Up
    sequence:
    - data_template:
        entity_id: climate.lyric_123456
        temperature: '{{ state_attr(''climate.lyric_123456'' , ''temperature'')|int + 1 }}'
      service: climate.set_temperature
