Hi guys !!!

Pretty new for homey.  
I discovered the limits of the 20 devices and I reached it !!!  
I have read many threads on the forum about this how to extend limit. I understood that my installation needed routers to extend the limit.

So I bought 2 aqara smart plugs, reset my zigbee mesh to add them first.  
I checked the route on the development tools, I have 7 devices in direct connection (screenshot below)

But, like the first time, I cannot add more than 20 devices to my installation. (Coordinator is count in the 20 ??)

**Do you have any idea of ​​this behavior, is there something that I did not understand?**

My zigbee installation is composed of battery devices and 2 routers, all from aqara (and 2 tuya).

Thank you for your feed back.
