Two systems wrongly shared

I have admin control over two battery/inverter/PV systems, my home one and a much larger one at a retirement home I'm a trustee for. The battery info seems to have become shared between them, such that when I programme the home battery to buy during the night this applies also to the retirement home one, where there is no overnight cheap rate. Any ideas how to disentangle?

Can't help other than suggesting local control apps rather than cloud based.

If on the GivEnergy cloud setup, they should probably be managed under different user accounts?
