Good time to consider making a next-generation Home Assistant Connect ZBT-2?
- Bump to a newer EFR32MG24 or newest EFR32MG26 chip?
- Add an external antenna?
- Add an electromagnetic shielding cover to EMF sensitive components on the board?
- Include a longer shielded USB 2.0 extension cable?
Maybe also make ZBT-2 in different colors to separate which firmware is preflashed from factory?
- Red color cover for Zigbee preflashed?
- Orange color for OpenThread (Thread) preflashed?
Save the color blue for Bluetooth and perhaps use purple color for Z-Wave?
Regardless I think it would be good idea for a complete hardware refresh with newer radio chip and external antenna.
