This CC2530 board is a complete ZigBee / IEEE802.15.4 transceiver / sniffer with an 8051 CPU and is suitable for Zigbee2MQTT. The board has a programming port and can be equipped with custom firmware that can serve as a ZigBee concentrator, for example. You can create your own ZigBee gateway and use it to control various devices such as lamps, temperature sensors, switches, etc. See here how to connect this board for flashing: https://www.zigbee2mqtt.io/information/connecting_cc2530.html For instructions on how to provide the board with custom firmware for zigbee2mqtt so that you can use it with Domoticz and other home automation, see the following sites: https://www.zigbee2mqtt.io/ You can also use an Arduino or an ESP8266 for programming. With a NodeMCU it is quite easy: https://www.zigbee2mqtt.io/information/alternative_flashing_methods.html More Domoticz information: https://github.com/stas-demydiuk/domoticz-zigbee2mqtt-plugin
