ZBDongle-E - flash or not?

FYI, Sonoff ZBDongle-E (Silicon Labs EFR32MG21 based) is not recommended for Zigbee2MQTT and is still listed as experimental only because Z2M does not yet support backup and restore for Silabs based Zigbee Coordinator adapters → Supported Adapters | Zigbee2MQTT

So if you are going to use Zigbee2MQTT then better to buy the Sonoff ZBDongle-P (Texas Instruments CC2652P based) instead and just flash the Sonoff ZBDongle-E adapter with Zigbee Router firmware in orde to re-purpose it as a dedicated stand-alone Zigbee Router adapter by powering it via a USB-charger.

Note that adding a few dedicated stand-alone Zigbee Router adapters are recommended regardless if using ZHA or Zigbee2MQTT as a Zigbee network depends heavily on its mesh networking technology.

I recommend not using multi-protocol/multi-PAN firmware and instead suggest using a separate dedicated radio adapter for each wireless IoT protocol that you want to use.

Also highly recommend you read and try to follow all the tips in these other threads:
