Be advised, that the RUT955 is supported running "official", most recent openwrt. Which not only allows community support, running more recent kernels and software packages, but also allows tighter customization for industrial apps. Having done multiple IoT projects accessing AWS and Modbus-RTU devices, using VPN, remote configuration, firmware updates OTA, failback WAN/WIFI/LTE etc.
This is not an option for industrial apps only, but also for the "casual" user, because of openwrts GUI.
