The rika_gsm component emulate the gsm module that can be installed on rika stove. It provide a way to send command and retreive the sms the stove want to send.

The GSM module share the same DA15 port as the ambiant temperature sensor at the back of the stove. The connection can be done by soldering new cables on sensor port or by creating a split cable to place in between.

Also the stove use 5v logic on the serial connection so some level shifting or protection could be required on your board.

Configuartion variables:

• pin (string): 4 digit string corresponding to the pin code set in the gsm configuration of the stove.
• id (Optional, ID): Manually specify the ID used for code generation.
• phone_number (Optional string): phone number use to communicate with the stove. No true sms are sent, this is a dummy phone number.

text_sensor:
  - platform: rika_gsm
    raw_status:
      name: "Stove raw status"

Configuration variables

• raw_status (Optional): give the last sms that the stove sent
  • name (Required, string): The name for the raw_status text sensor.
  • id (Optional, ID): Set the ID of this sensor for use in lambdas.
  • All other options from Text Sensor.

binary_sensor:
  - platform: rika_gsm
    gsm_status:
      name: "GSM status"

Configuration variables

• gsm_status (Optional): indicate if the gsm option is set on the stove
  • name (Required, string): The name for the gsm_status binary sensor.
  • id (Optional, ID): Set the ID of this sensor for use in lambdas.
  • All other options from Binary Sensor.

When the gsm option is set the stove try to read if their is a new command every 5s. If their is no stove request after 10s the gsm option is considered deactivated and will be concidered active on the next stove request.

Send a command to the stove.

    then:
        - rika_gsm.send_command:
            command: "ON"

Configuration options:

• command (Required, string, templatable): command sent to the stove
