Also note that a “ezsp adapter” Zigbee Coordinator is not currently recommend for Zigbee2MQTT, so consider buying the CC2652P based “Sonoff ZBDongle-P” to use as a Zigbee Coordinator instead and later convert that “Sonoff ZBDongle-E” into a dedicated Zigbee Router device by refreshing its firmware and then power it via a USB-charger as a stand-alone Zigbee extender/repeater device → https://www.zigbee2mqtt.io/guide/adapters/#recommended
