Sensible maximum number of repeaters between a coordinator and a Zigbee device?

Configuration Zigbee

I’m running two Zigbee networks at the moment. ZHA over skyconnect and z2M over Sonoff, due to some technical problems that I’ve been having, which I thought I might be able to fix by changing from ZHA to Z2m (conversion for another thread).

Given this, I’ve split my repeated up between the two networks.

Ideally I’d like everything to connect to a repeater which then connects directly to a coordinator, but some of my devices are too far away to do it in one hop.

putting the exact signal strength to a side for one moment, as that’s an entirely different can of worms, what is the sensible maximum number of repeaters I should have between any one device and the coordinator when running under “less than ideal circumstances”.

Can I get away with three hops, or four, or doesn’t it matter until half a dozen (again, putting the signal strength aside, just the number of hops)?

Since you have very little control over the actual routing, the better goal is to have enough routers that there are multiple available paths from any given device to the coordinator.

You can lead Zigbee devices to a router, but you can’t make them route.

In other words make sure there’s plenty, and it will (or should) do it’s thing., as Drew said.
That saying just popped into my head so I wanted to share a smile.

I’m having to daisy chain them right now as my network has essentially been sit in half as I’m now running zha and z2 at the same time.
