Hi. Im using firmware FW ver.: RUT9XX_T_F1875_00.06.05.28 on RUT955 (special firmware with profile save fix) and when i use the digital galvanic isolated input and set rules when going low to high, or high to low to send SMS, the SMS are not sent. using the passive digital input works fine. Can someone at Teltonika please verify if this is a bug with the special firmware, and if there is a fix?
