TRB246 sends unexpected “Low” SMS despite configuration for “High” only

Hello everyone,

I’m using a Teltonika TRB246 router and I want to receive an SMS only when the Input(2) state goes “High.” However, I keep getting random SMS messages that say “Low,” which I don’t want. Below is my current configuration:

  1. Input Pin 2 Setup
  • Mode: “Configurable Input”
  • Custom high state name: “Alarm 1 ON”
  • Custom low state name: (left empty)
  1. Event Juggler Configuration
  • I created a new event with the following parameters
    • Event name: SMS_AL1_ON
    • Trigger interval: 1
    • Event type: I/O
    • I/O pin name: Configurable Input/Output (2)
    • Trigger: Rising
  1. Action Data Configuration
  • Action name: Send_SMS_IF_Alarm1_ON
  • Action type: “Send SMS”
  • Text message: %g1
  • Recipients: “Group” (Phone group: PhoneGroup1)
  • Condition compatibility: “And”
  • Active conditions: Condition_Input2_High

  1. Condition Configuration
  • Condition name: Condition_Input2_High
  • Condition type: I/O
  • I/O pin name: Configurable Input/Output (2)
  • Pin state: High

Despite this setup, I receive random SMS messages showing “Low” at unpredictable times. I specifically want to avoid any SMS for the Low state. Is there a particular setting I’m missing or a different approach to ensure that the device only sends “Alarm 1 ON” SMS messages for High and never sends a “Low” message?

Thank you!

Can anyone please help? My client will soon have to renew the SMS payment for his SIM card if he continues getting so many messages.

Thank you!

Hello,

Thank you for reaching out.

First, could you confirm if Pin 2 is set as Configurable Input in the Services → Input/Output → Status page?

Additionally, for a more optimized setup, the condition should be configured to trigger an SMS only when Pin 2 state is Low, so that when it transitions to High, the SMS notification will be sent. For reference, check the screenshot below:

Let me know if this helps or further assistance is needed.

Kind regards,

Hello Martynas,

I can confirm that Pin2 is set as Configurable Input.
I will adjust the condition for Pin2, test it, and keep you posted on whether it resolves the issue.

Thank you for your assistance and detailed response.
