Updated to Philips Hue Pro - Broke Homey Pro Mini Zigbee

Recently installed a Hue Bridge Pro to replace my two older Hue Bridges and get everything in one place, Home Pro Mini Zigbee is very very poor now, not picking up devices when they were rock solid etc.

Philips Hue - I moved to Channel 15
Home Pro Mini is on Channel 25

Any insights as to what to do?

Are you certain the issue is caused by the Hue bridge and not by, for example, a recent Homey firmware upgrade?

Does your network start working properly again when you power off the Hue bridge?

It started in the evening of the day I installed the Hue Pro. So before the recent Homey firmware update.
I shall switch the Hue bridge off and see if things improve - might take a while though, lots of flows use the Hue bridge

Unplugged the Hue Pro bridge and things improved slightly.

Switched the Hue Pro back on and things have stabilised.

Coming back to this after a couple of weeks, the Homey Pro Mini Zigbee is once again not working properly.

Removed all the Zigbee devices,
Reset the Pro Mini Zigbee - through the developer webpage.
Re-added the devices one at a time and routers first - then end devices.

Worked fine for about 24 hours

Now half the devices are unreachable once again.

Where can I find the signal strength or some sort of network map for the Zigbee network (similar to what Zigbee2MQTT provides)

All this since I installed the Hue Pro

Exactly, only Z2M provides for many tools, monitoring and alerting.

.

In that case one interferes with the other, you should tune the zigbee channels.

AFAIK it’s the easiest to change the zigbee channel on Hue, but turn on all connected devices prior to changing.
Also check on your 2.4GHz wifi channel number!

Very useful info:

So after much tinkering I decided to go on a different path.
Realised the issue wasn’t going to be resolved using the Homey Pro Mini as the only Zigbee Coordinator, the Homey Pro Mini runs the Zigbee network in part of the house.

I had a spare Sonoff ZBDongle-P and a raspberry Pi lying around, which I can access through the Zigbee2MQTT app in Homey which I now use on a different channel in the further reaches of the house.
I now have Hue on Channel 25, Homey on 20 and ZBDongle on 15 so they all seem to work quite well.
One huge advantage with the Zigbee2MQTT App is that Devices show their LQI directly, very useful information, shame the Homey built in Zigbee doesn’t do the same.
I am not sure why the Hue Pro caused this interference but at least I have a more stable network now.
Thanks for everyone’s input.
