Two openHAB2 and one Internet provider/WAN-IP

Hi there!
I share my internet with my home and my office and i have two different openHAB setups.
The openHAB for my home is connected with myopenhab.
Now I want to do the same with my office setup so my employes can acces myopenhab.
I will register my office openHAB with my work email.
The question is:
Can I do this without setting up ports and forwarding in the router?
I don’t want them to interfear with each other…

Should be fine. When you set up two different openHAB cloud accounts, they’re differentiated by the UUID and Secret that is unique to each openHAB server.

Thank you!
I will try it!
