Hey, currently i have nothing but i’m moving houses tomorrow and next week i’ll start my smart home dream, so if u have any suggestions feel free to give some tips
I don’t have such a big ZigBee network, but Homey (or any ZigBee hub) likely can’t handle that many ZigBee devices. This means you’ll have the spread your devices (for example Hue devices on 1 or more Hue bridges, Tuya devices on 1 or more Tuya bridges, the other devices directly on Homey). You can also use multiple Homey Pro’s with the HomeyLink app
You can also integrate the Hue and Tuya ZigBee bridges with Homey, using their apps.
So for example a homey pro for each story in the building, so each story a seperate homey pro + zigbee network?
It could be that way. Could be “Homey” + “homey bridge”.
Homey + Homey2019….
Could be “Homey” + “Philips hue bridge” + xiaomi bridge + tuya bridge+ wiz (wifi) +wled(wifi)…

haha, they are smart bulbs so i gueas led max 10w so 2 to 3kw but i understand the joke 
Pfff why is it so difficult
Homey currently manages 347 devices and over 1,000 entities for me. This number consists of early26, early23, Hue Bridge and Home Assistant devices.
Of course, not all of these are Zigbee devices. I estimate that a maximum of 10% of them are Zigbee. I just wanted to show what Homey early26 is capable of. The number comes from a Home Assistant integration that imports all devices from Homey.
How many zigbee’s do u have?
maybe 35 pieces
I have 71 Zigbee devices on a Homey Pro 2023.
And it runs stable?
It works for me, but 35 pieces are peanuts for Homey. I only had one Osram Lightify ceiling light, which sometimes didn’t work. I’ve now registered it via Home Assistant, and everything is fine. But Osram has never liked Homey.
So i’m guessing 100 zigbee devices would work decent enough
You know that there are other wireless protocols besides Zigbee. Zwave is at least as good.
I’ve had the best experience with WiFi. With a powerful router, 100 devices are no problem at all. I have over 100 Shelly and X-Sense devices running.
The Homey Pro (Early 2023) can manage a very large Zigbee network, although the actual number of devices supported depends heavily on the network structure.
Maximum number of Zigbee devices
There is no fixed upper limit for the Homey Pro (Early 2023) as there is for older models, but performance depends on the number of router devices.
Athom recommendation: Athom itself suggests that a stable network can comprise around 80 devices, although some users successfully operate more than 100 devices.
Network structure: The total number of devices can be significantly expanded by using mains-powered devices as routers (e.g. sockets, lamps). These relay the signal and relieve the Homey Pro coordinator.
Theoretical limit: Technically, a Zigbee network can support tens of thousands of nodes (up to 65,000), but in practice this is limited by hardware and software constraints.
Again, I personally doubt this.
Also consider that Homey doesn’t support Zigbee groups, which means that if you have light fixtures with multiple lights, Homey needs to send a Zigbee command to each light individually. Experience has taught us that Homey simply cannot do this reliably, which results in some lights getting switched while others don’t. Also, sending a large number of Zigbee commands at the same time is a good way to cause stability issues in your Zigbee network.
Some additional considerations for building your Zigbee network, which you might already know:
- Place your Homey Pro (or other Zigbee adapter) in a central location of your home
- Start building your network by adding your router devices first, starting with the devices closest to your Homey/Zigbee adapter, gradually adding devices further away.
- Finally add your end devices
I have this problem with wifi devices. Specifically with wiZ. (with “wled”, I don’t notice this problem.)
Don’t forget RAM. The more titles, the less RAM.
Yes, this is an issue with Homey in general. Has been for a long time.
Yes it does

Note that regarding smart lights: exceptions aside, I chose to not make lights themselves smart (so not using smart bulbs), but to make the wall switches and plugs smart. I only need to switch on/of lights and in some cases dim lights. I am not using colored lights. As such in my case smart bulbs are not needed. This reduces the number of Zigbee devices needed.
The point @robertklep mentions about Homey not being able to control Zigbee devices as a group (in a sense that it sends only one group command instead of addressing each device individually) is indeed a thing.
A work-around is to control your devices in series instead of in parallel (so send commands after each other instead of at once). From a user experience this means that e.g. in a group of lights the individual lights do not switch on at exactly the same time, but there is a slight delay: they switch on after each other.
In the end, at least in my case, all lights are switched on. My Homey never missed a light. Even in the incidental extreme case, Homey did switch on all lights eventually after several seconds.
