Reading and writing modbus register - SOLVED

Configuration
1

Hi,

I have made some progress with my Modbus controller. I can now read temperature value from it using Modbus TCP. Next step is to create a switch for turning on/off the heating. In my configuration.yaml I have:

modbus:
  - name: "ouman_garage"
    type: tcp
    host: 192.168.1.60
    port: 502
    delay: 0
    timeout: 5

    sensors:
      - name: "Garage heating ON/OFF"
        address: 132
        count: 1
        input_type: holding
        scan_interval: 5
        slave: 1

    switches:
      - name: "Garage heating ON/OFF"
        slave: 1
        address: 132

Basically I have created a sensor and switch. Modbus register is 132. In the scripts.yaml file I have:

script:
  description: "Garage heating"
  sequence:
    - service: modbus.write_register
      data_template:
        hub: ouman_garage
        unit: 1
        address: 130
        value: 1
    - delay:
        milliseconds: 100
    - service: modbus.write_register
      data_template:
        hub: ouman_garage
        unit: 1
        address: 132
        command_on: 100
        command_off: 0

Idea is to write first “1” to register 130 and after a short delay to write to register 132 either 0 (=off) or 100 (=on). My problem is that I donät understand how to pass the on/off information from the switch in the configuration.yaml to script.yaml. Any help would be appreciated. Thanks.

Managed to solve this problem. Don’t remember exactly what was causing problems but at least I changed in command_on: 100 to “100”.
