Hello, I’m on homey 2023, I had a lot of devices in wifi then I started with zigbee devices. The first time I messed up, the network was not stable. So I’m going to redo it from the beginning according to the rules (the right zigbee and wifi channel, adding the routers in order then the end devices). It worked well, so I’m in the process of replacing what I have left of wifi bulbs with zigbee ones. Now the network no longer seems optimal, some bulbs no longer respond to automation randomly (they are LEDs on ceiling lights, so right next to each other). I also have 2 homey bridges in the house. The additional bulb installations date from last night. Is it possible for the network to stabilize itself after a certain time? The idea is not to have to redo everything 
Thanks in advance for your thoughts
How many Zigbee devices do you now have in total?
Or…
If you are going to re-do everything anyway; you might wanna consider installing (i.e.) Zigbee2MQTT with a Zigbee dongle like the Sonoff Zigbee dongle P and have a REAL stable Zigbee network…
But you need a place for installing it of course; NAS/Docker, RPi, etc.
Best thing I changed on my Homey environment in years… 
29 routeurs and 23 enddevices. It’s on the ground floor that I added routers and it no longer works well. Upstairs everything is perfect.
A place to put it, you mean the USB connection? I read that it is connected directly to Homey, but then the Zigbee devices are connected to Homey or to the dongle? Is it the dongle that manages the communication between Homey and the devices? Let’s say that I bought 2 Homey bridges for Zigbee, it hurts the wallet
It sounds like you may have reached Homey’s limit for a stable Zigbee network. There are so many issues with the multiprotocol firmware (that Homey uses) that others (like Home Assistant) have stopped developing for it, and strongly recommend not to use it anymore. It’s not possible to disable it on Homey though, so you’re stuck with it.
I know, but aren’t homey bridges supposed to increase the limit?
Check: Getting started | Zigbee2MQTT
and: [APP][PRO] Zigbee2MQTT
That is a good place to start.
A separate Zigbee dongle is connected to a NAS, RPi or other.
The devices are connected to this dongle and “imported” in Homey via Zigbee2MQTT App for Homey | Homey
No, they just increase the Zigbee range evt, as they act as ordinary routers, like for example (almost) any light bulb or outlet.
The strange thing is that it’s only the lamps in the flow via moods that are causing problems. The sockets have no problems, the lamps when I activate/deactivate them individually via the homey application react well
Try creating a flow that does what your mood does, and check wheteher is also has issues.
Might be the mood implementation having bugs.
As @Henk_Renting already explained, they don’t increase the limit, they act as normal routers in your network, so they extend the range of the network.
Using moods sends commands to multiple devices at the same time, that’s something that Homey has struggled with for many years already. And using the multiprocotol firmware doesn’t help things 
No, it doesn’t change anything. I tried giving orders 2 by 2 on a ceiling light with 4 bulbs instead of all 4 at once, there are also bugs. However, it seems that it’s the new devices added the day before yesterday that are causing the problem. I’m going to try the reset, it’s a pain, but I’m on vacation, it’ll keep me busy Otherwise, I’ll replace the matter bulbs where the problem is occurring.
I’d start replacing the Matter(-over-Thread?) devices you added last.
With a big(ger) zigbee network, you’d better not use Matter-over-Thread devices. In other words, you should make a choice: use either zigbee or Matter-over-Thread devices.
Of course Matter-over-Wifi devices aren’t using the multiprotocol Zigbee/Thread chip, and should not cause zigbee issues.
To me it sounds you built the zigbee network the right way, don’t ‘start all over’ yet, I’d say.
But IF you actually want to start over, I agree with Henk, I can recommend zigbee2mqtt by 100%, using it myself.
I built my zigbee network well at the beginning, the matter bulbs that I replaced in the kitchen are already more stable, the sockets in several rooms react quickly without problem. It seems that it is in fact mainly in the Laundry room that it is stuck. It was stuck a little in the kitchen, a lot in the Laundry room. I cut the power in the Laundry room, the kitchen is stable (homey is in the living room then it is the kitchen, then the Laundry room). There is 1 homey also in the Laundry room and 1 modem (mesh network). There is also the fridge, the machines and the boiler… Maybe interference? I will replace other matters in the hallway tomorrow and see how they behave but I wonder if it would not be the room that is causing the problem… Zigbee2MQTT seems good but complicated for me i’m afraid
About interference
(Any 2.4GHz wifi signal can interfere, like the neighbours’ wifi signals).
“Must” read:
I missed that you may also be using Thread devices. If that’s the case, all bets are off, because even though Homey is sold as a “supports Zigbee and Thread” device, using both protocols is a recipe for two unstable networks.
I mostly use matter, I only have 3 aquara thread and matter but that I had associated in matter. In doubt I will try to remove them
It’s not the WiFi channel, I checked but maybe the mesh modem is still too close to the bulbs (it’s above a 2m high piece of furniture 2m away from the bulbs)? Thanks for the link, I had already seen it but I couldn’t find it anymore
