Homey bridges don’t have ethernet connectors, and can’t be extended with an ethernet dongle like with the Pro23.
But how would you use bridges as Pro23 satellites controlling different rental units. Not possible.
Well, a bit when it comes to one rental unit: It’s possible to select the bridge as 433Mhz/IR antenna-over-(W)LAN for any 433/IR device, IF the accompanying apps support this functionality…
So i think you’d use either Homey Cloud + bridge (only when you need local radio like zigbee/zwave/bluetooth/433MHz/IR; Cloud-2-cloud apps don’t need the bridge),
or a Pro in each rental unit.
Homey cloud depends on uninterrupted internet and Athom cloud continuously btw.

When using multiple Homey Pro only: Sort of.
By using webhooks, and or using the Homesh app set.
