Error "running script requires passing in a context" | Fancoil Modbus Integration

The problem

Hello,

I have fancoil wired in a modbus rs485 serial network. I want to use hass-template-climate component because i have to do math with some modbus registers and the standard modbus climate component doesn't allow to do that and also lack of the fan_mode functionality.

I have set all as in the .yaml attached. all readings are fine but when I try to execute an action like 'set_temperature', 'set_hvac_mode' or 'set_fan_mode' nothing happen and the value is restored to the original one. I have tried to execute the service 'modbus.write_register' on the 'developer tools' tab and all of them work. In the log I see "running script requires passing in a context"

What's going on? How can I fix this?

Thanks

Your problem is that when you're calling your services, you're using values from the template-cliame entity. However, at that point the climate entity is not holding the new values you've selected from the card interface. So you're just passing the unchanged value before you change it.

What you need to do is to use the specific variables provided by the template for the appropriate action you want to do.

here is a suggestion:

  set_temperature:
    - service: modbus.write_register
      data:
        hub: fancoil_hub
        slave: 2
        address: 231
        value: "{{ temperature | int * 10}}"

  set_hvac_mode:
    - service: modbus.write_register
      data:
        hub: fancoil_hub
        slave: 2
        address: 233
        value: |-
          {%- if hvac_mode ==  'heat' -%}
            3
          {%- else -%}
            5
          {%- endif -%}

  set_fan_mode:
    - service: modbus.write_register
      data:
        hub: fancoil_hub
        slave: 2
        address: 201
        value: >
          {% if fan_mode == 'auto') %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65528) }}
          {% elif fan_mode == 'low') %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65530) | bitwise_or(2) }}
          {% elif fan_mode == 'medium') %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65529) | bitwise_or(1) }}
          {% else %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65531) | bitwise_or(3) }}
          {% endif %}

  set_swing_mode:
    - service: modbus.write_register
      data:
        hub: fancoil_hub
        slave: 2
        address: 201
        value: >
          {% if swing_mode == 'on') %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_or(128) }}
          {% else %}
          {{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65407) }}
          {% endif %}
