How would I handle getting Zigbee to an outbuilding 150ft away?

I am just setting up a home automation system in my house and I have come up with a snag. I’m new at this but I have read that Home Assistant cant handle more than one Zigbee Coordinator (or am I wrong). So how do I connect to my sensors in my outbuilding? I already have ethernet in the outbuilding.

More than one coordinator per control stack. HA supports multiple stacks

Use ZHA (the builtin) for one network and Z2M (addin) for the other… Two coordinators - one per software stack.

I’ve never used it, but there is this.

Good info, thanks.
Obviously I’m new to this.
I just ordered an SMLIGHT ethernet Zigbee module and I’ll give it a shot.
