I’ve hit a ceiling with my Electrolama zzz! zigbee stick (144 devices) and so will be changing and seeing as I’m going to make a lot of work for myself, should I consider going from the Blue to either the Green or Yellow? Is it worth it?
And which Zigbee stick? Something Ethernet or PoE?
Changing from Blue to Green or Yellow won’t do a thing for your Zigbee problems.
A coordinator based on the EFR32MGM24 should work with a network of 300 devices (but since you will switch from zstack to ember, prepare the switch carefully)
The CC6252P7 also has more memory then the CC6252, ans so can handle more devices.
