Zigbee router to extend network that doesn’t require mains power


I’m losing signal between my Zigbee Bridge Pro and some of my end devices such as a door sensor. I would like to purchase a router to extend the length of the network reach.

However I live in South Africa where we have power outages for 2 hours everyday. It is VERY important the security continues working during power outages.

The end devices have batteries so they continue working, and I power my Zigbee Bridge Pro with a mini UPS via a USB. The mini USB provides 5V for USB or 9V or 12V.

I need recommendations. What device would work as a router that does not require being wired into mains power? Something that runs off USB or a 9V or 12V transformer. Are there options other than the ZBMini? The ZBMini would stop working during loadshedding so really isn’t reliable.

If I could purchase a second Zigbee Bridge Pro and use that as a router that would work but I can’t see any topics about this. It seems the Bridge Pro is a coordinator and not a router.

So can the Zigbee Bridge act as a router or not?

We will gradually reply to the topics under the existing “help & feedback” category and unlist them. After that, we will close the “help & feedback” category and no longer reply to related topics. This will allow us to spend more time discussing about ideas and feature requests.

Let’s build a forum with funs and ideas, thank you for your understanding, deeply.

Hello, Actually I didn’t realise I must have asked my question in such a confusing way. It seems so easy to understand.

The issue is not a software issue or a problem with an existing device otherwise I would have contacted Sonoff. The question is aimed at users as free discussion.

In Zigbee the devices fall under one of three categories: Coordinator, Router, and End Device.

  1. You can only have one Coordinator in the system - Typically the Zigbee Bridge or the ZIGBEE 3.0 USB DONGLE PLUS.
  2. Routers are used to extend the reach of the Zigbee network - quite a common need I would have thought.
  3. End devices are things like door sensors, and cannot function as routers.

I’m just asking what devices other than ZBMINI or S26R2ZB function as router and hence able to extend the length of the network? Surely someone in the public has some ideas? And if there are no options I’m also wondering if purchasing a second Zigbee Bridge can function as a router maybe?

My problem is loadshedding in South Africa. Our electricity is turned off everyday for a few hours, so the ZBMINI and S26R2ZB basically stops working during this time, hence rendering the security system a bit useless when you are in the dark. This is really when one needs security most!

Did you unlist my question? I have a genuine need to find out more information about Zigbee network.

I have assign and reopen this topic to “free discussion”, unlist is a bulk action of all topics in “help” category.

Hi, you can use a Zigbee Smart Relay card that you can power over USB. The 1 and 2 gang versions works with ZB Bridge Pro, the 4 gang version only works with the normal ZB Bridge and does not work with the ZB Bridge Pro. All the models have ROUTER funcionality what is required to extend the Zigbee mesh network.

Hope this helps.

This definitely helps!! Thank you!
I actually own two of these Zigbee inching relay modules sitting in my cupboard, but had no idea they could also be used for this purpose!
