Hello,
Please, ensure that you enabled monitoring for the device in the RMS settings. Select your device in RMS, click on the ‘device tab’ and then on ‘manage services’. There, enable monitoring for the device.
Additionally, there were improvements made RMS connectivity in the latest 07.04.5 firmware version. Thus, if the issue persists, could you please update the devices and see if it connects then?
Kind Regards,
