Homey Zigbee - limit of 20 battery powered devices

Hi Guy56,
Many thanks for the confirmation for the way to go, sounds logical :wink: Did you implement it ? What about removing a device playing role of extender like a lamp or power socket, could we remove it from the Zigbee mesch by command in a workflow ?

Then it is a generic zigbee issue when it’s in a specific hardware setup (SoC/Memory/etc) as described…

Thats not the mesh layout, thats the routing list.
Look at the post made earlier: )

Something cannot be both generic and specific :stuck_out_tongue:

To clarify: it’s not a generic Zigbee issue because the limit isn’t imposed by the Zigbee standard.

Ye i know both the meaning of that word and the sentence as a whole. and the insights of this “issue”. and again, read my post, never said it was a generic flaw across the board. Just a common limitation in specific hardware environments. (As earlier stated).
If its easier for you just put in “hardware environment” in the specific-part if the sentence. And generic you can change to general/common, then perhaps the sentence get simplified when someone isnt used to eng.

in dutch ill guess its same as algemeen / gemeenschappelijk…
Iam not Dutch, used google for that part.

Don’t be patronizing.

No worries i wasnt, just explained, to prevent misunderstandings.

Then it’s a good thing I never said it’s the mesh lay-out. However, it’s my understanding that, based on the routes, you can work out how your mesh is set-up. So in my post, the ikea light bulb is used to pass on the messages between the aqara motion sensor and homey. Are you telling me that’s false?

Nope, i never said that. I just said it’snot the mesh you see under the “dev’s page”, its the routing table on active nodes. I linked the other guy’s post down below.
And yes, you said mesh. I was just saying the same as the guy before you, so you dont mix the 2 things up. Especially when you are troubleshooting it, your Zigbee network.

Your post.

The guy’s post: post

It would be very good though, if it would generate the mesh-layout. So you both have the active routes (routing table) and mesh with the alternatively routes/jumps.
So you can have a complete overview on the topology of your Zigbee network.

I still cant understand, why such an expensive device can only handle max. 20 direct zigbee Connections. Is it the same for the Pro model?

  • Hue Hub allows 50 direct connections
  • Hubitat allows 32
  • SmartThings I think is at 64

If you are good in DIY, maybe you can extract a Zigbee chip from an ST and put it on the Homey motherboard?

  1. That was not my question.
  2. According to this it‘s an SoC issue and DIY work wouldn’t help…
  3. It isn‘t really clear if the threshold is only for battery powered devices or for all devices. Can somebody help?

3: What is it u don’t understand at Roberts comment?

Ok.

1.) Yes, it’s the same for the Pro
3.) 20(-ish) in total, for ALL devices

Why is it limit? I have 30 devices out of which only 2 are directly connected to Homey. Why dont ppl just buy pair of ikea sockets and never need to solve the issue?

Because what works in your specific situation may not work on someone else’s specific situation.

What is specific about my setting? I have two story house with homey and three routers around (2 upstairs, 1 downstairs).

Your home layout, the materials your home is built with (walls, floors; for instance, in NL lots of houses have concrete floors with rebar reinforcements, which are very prone to cause interference), any large pieces of furniture, location of Homey, location of Zigbee devices, number of WiFi networks in the vicinity, etc.

How do type of walls correlate with number of devices (not signal strenght)? If the issue is number of maximum devices than additional router solves problem. Nothing more nothing less. BTW i have monolitic concrete floors/ ceiling.

If the issue is signal strenght than you just add even more routers. But its not what the topic here is about.

Your solution was “Why dont ppl just buy pair of ikea sockets and never need to solve the issue?”

That’s too simple, because:

  • you cannot tell end devices which router to connect to; in your specific situation most end devices connect to the routers, but that will not happen everywhere
  • a “pair of ikea sockets” may not be sufficient
  • if you already have a large number of end devices, and you start adding router devices, you may not be able to add them because you’re hitting the limit while adding the routers, and …
  • …some end devices, like Aqara, don’t like to switch routers, so if they got paired directly with Homey and you add additional router devices, the Aqara’s may not switch to using those router devices.
