If you have SSH access to the devices and valid credits in RMS, you can execute the following command to unregister the device from RMS:
- uci set rms_connect_mqtt.rms_connect_mqtt.remove_from_system=1 && uci commit && /etc/init.d/rms_connect restart
Otherwise, it is possible to remove MFA authentication, but before that, more details are needed to determine that the account is yours, thus, I would like you to provide answers to at least some of the following questions:
How many devices (roughly) are registered to your RMS account?
Do you know any of the serial numbers of these devices? Please write them.
When was the approximate last time, when you successfully connected to this RMS account?
What were the last actions, you did on your RMS account?
What is the company ID and Email address associated with the account?
Send those answers to me in a private message.
