Zigbee repeaters?

@zombieuhrise

what is a low ram repeater? which would be a high ram repeater?

Here is the best explanation I've seen of that on the forums, or basically, the takeaway is that only the hub will be a "high RAM concentrator," assuming that's what you are referring to:

@srwhite

The concept of high/low ram only applies to concentrators. A concentrator (or coordinator) is the hub in the Hubitat world. Whether a coordinator is high ram (full route table) or low ram (partial route table), route discovery can still happen since Zigbee is a self-updating mesh protocol.
