It is running unstable and will not turn on the light when the switch is activated, or it is delayed 5 to 10 seconds.
The System CPU Clock is high (see picture below) and I have 67 zigbee devices attach to the Homey.
Is it a problem with 67 Zigbee devices??
I have also looked in the Developer tool and I can see that the app performance for the apps is approx. 34.6 MB for Memory (PSS) and 70 MB for Memory (RSS) for each app. I have 6 app´s in total.
Can you share CPU utilisation and CPU frequency for eg. 6 hours only or 1 hour ? Btw best is to install sysinternals to diagnose such kind of issues but first I would probably follow on questions raised by Robert, as Zigbee devices are kind of specific…
Regarding the zigbee devices is it random which are working or not.
I am controlling all the light in a 2 floors house.
The zigbee devices are mostly Nordtronic Box Relays and LED drivers.
The Nordtronic Box Relays are activated by the light switch and the nordtronic relay are then sending the signal trough the Hoemy to activate the LED drivers. It could be that 5 Led drivers are activated by one zigbee Nordtronic Box Relay.
The Led drivers and Nordtronic relays are placed in clusters between 1 to 20 units could that be a problem? I mean could the zigbee signal from the different units get blocked?
I can see that all Zigbee units are listed as Routers and the Homey pro as coordinator. Is it correct that the homey pro 2023 could have more than 65 Routers? I can see that the previous versions of the homey only could handle 15 Routers.
In that case it’s probably caused by Homey simply not being able to control multiple devices at the same time (an issue that has existed for many years now, so will likely never get solved). When it does, commands get lost and you end up with a random selection of devices that will receive the message while others won’t.
You probably have to look for workarounds like using the <group> app that can mitigate this issue by commanding the devices sequentially instead of in parallel.
Maybe take a look at this topic: [HOW TO] Plan and setup your Zigbee network
It says that the maximum number of devices/routers directly connected to Homey is 64. But I don’t know if this is correct.
However, it’s also quite possible that routers don’t connect directly to the HP23, but via another router. So in theory it shouldn’t be a problem.
But switching many devices at the same time can be a problem, as @robertklep already mentioned.
During the last months I have worked with the issues mentioned above and I have not succeeded. The Homey Pro is still not working properly.
The issues are.
When the wall contacts are activated, the light is not always responding or only some of the lights are responding.
If I use the app to activate the light it is working much better.
Observations.
When I look in the Homey developer tool at the wireless Zigbee devices I can see that some of the devices have not been seen for days or weeks. Why is that??? See picture
* When I ping the devise with high last seen it is responding again to activation with wall
contact.
* After some days it is a new device that has the same issue.
I have installed 4 additional Homey Bridges to improve the wireless coverage, but it has not solved the problem.
This isn’t a Zigbee issue but a Homey issue: Homey simply cannot send commands to multiple devices at the same time without some random commands getting lost. This has been an issue for years now, so we have to assume it cannot be fixed.
You can try using an app like < group > to work around the problem, as that has the option to introduce delays in between the commands when controlling multiple devices.
It is more that the homey stop to see (communicate with) some of the components and when you then activate the wall contact it is not responding until you ping it.
Is there an app that could ping components that not have been seen for some time???
Double checking : are all zigbee relays and led drivers powered all the time and not disconnected from power somehow?
And I read you have clustered relays and/or led drivers together. Do you mean physically cramped next to each other? If so, that could be part of the problem.
