I’m not sure what the point of this topic is currently.
It is widely known that the older Homey Pro and Bridge’s ZigBee chip has a limited memory, in theorie it can handle up to 20 devices connected directly, but this is limited in software to 15 by Athom (probably with a good reason).
It is widely discussed on this forum.
And it is also shown on their support pages (as shown in the first reply) that this limitation is there, and if you want to connect more devices you first need to connect (multiple) routing devices.
Please also update your title of this thread, this is non descriptive at all.
