Zigbee buyer's guide

I am bit little confused.

SMLIGHT SLZB-06 is recommended when using Z2M
SMLIGHT SLZB-06 M is recommended to use with ZHA

But smlight website says that EFR32MG21 can work with Z2M and In practice, these chips show more stable operation than CC26* in Zigbee coordinator mode.

Is it future-proof today to get SMLIGHT SLZB-06 M with EFR32MG21 when planning to use Z2M ?

Read my recommendation and explanation in the post above → Zigbee buyer's guide - #2 by Hedda

Summery; Silabs adapters are not yet recommended → https://www.zigbee2mqtt.io/guide/adapters/

As well as note this warning:

WARNING! WiFi-based Serial-to-IP bridges are not recommended as the serial protocol does not have enough fault-tolerance to handle packet loss or latency delays that can normally occur over WiFi connections. See these references that same recommendation applies to both Zigbee2MQTT and ZHA:

• https://www.zigbee2mqtt.io/advanced/remote-adapter/connect_to_a_remote_adapter.html
• https://www.home-assistant.io/integrations/zha#warning-about-wi-fi-based-zigbee-to-serial-bridgesgateways

In short, if want a more stable Zigbee setup then do not use Serial-to-IP remote adapters over Wi-iFi.
