@Vincent-TP I am currently managing 5 sites on Omada essentials, we decided not to add omada hardware to save power as we are running our entire setup on solar, so it is essential to be able to create voucher groups.

Hi  @ludbarri 

I have to tell you that it's not possible to add portal authentication on Omada cloud essential controllers in a short time.

Maybe you can use a hardware controller OC200; it won't consume much power.
