Please adjust your RUT-OS so that it is possible to install node-red at least on an external ssd, because in that case you would really have the most serious and useful LTE industrial device in the world.
For a year I have been testing your devices in all possible conditions and with all VPN services, wireguard, zerothier, l2tp, pptp etc... with external antennas where there is not enough signal in rural conditions and I am really satisfied.
My only complaint is that there is no node-red. If they had that, I think they would greatly improve sales and practically disqualify Raspberry Pi and Mikrotik
Best regards
