When and where to add more Zigbee repeaters?

I've just significantly increased the size of my Zigbee network, and I'm wondering if I need an extra repeater helping out. It looks like many of my devices are connecting directly to the hub, and some of my devices are not listed either as children or in the routing table. Is that a concern, or is it normal not to see all devices listed?

How large is your zigbee network? In my 83 node network, which has been very stable for about 3 years, I have one router for every 4-5 end-devices.

I have 39 now if I'm counting properly, of which 3 are repeaters. So... Not the ratio you have. :wink: I actually didn't realize how large it had gotten.

You probably have plenty as far as routing power. You could add more to strengthen signal if you wanted. Plugs are so cheap, there is no reason to have a weak signal.

If you have nothing that you want to control with a plug go ahead and plug in those little Glade plug in oil warming air fresheners. You can get some serious mileage out of them if you automate them to not run when your not home.
