HiLetgo Wireless Zigbee CC2531 Sniffer Bare Board Packet Protocol Analyzer Module USB Interface Dongle Capture Packet Module

Bought one to replace my SmartThings hub with Zigbee2MQTT. I 3D printed a case for it and was able to do the RP-SMA antenna mod to increase the signal strength. I flashed the Z-Stack firmware on it using an ESP8266 board and some alligator clips. The pins are very small so be careful not to accidentally short any connections. Zigbee2MQTT detected it without any issue, and I was able to add some light bulbs and remotes without any problem.

I ordered this by mistake I thought it was something else but nonetheless it still was a good product.

This uses an old chip that is not recommended any more, although it will work. It comes without firmware and must flashed, not hard... if you have the hardware to do it. But most important, the on-board antenna is terrible.

I re-flashed this for use with Zigbee2MQTT and Home Assistant using a Raspberry Pi and some alligator clips. Had to bend the pins to get the clips to fit, but it wasn't hard.It's a good value, and works as expected. The range isn't great. If you're willing to wait for shipping from china, you can get these with an antenna for a similar price on other sites. If you are like me and you want it in a more timely manner, this is the way to go.It paired easily with both of the devices I tried so far (SmartThings Button and Aqara Temperature and Humidity Sensor).The range is OK. I have a 1400 sq/ft house, and this will reach from one end to the other, but didn't work from the garage or yard. If I was more patient, I would probably get one with an external antenna, but I don't regret this.

Didn’t work, tried it with lots of different configurations, but probably got a broken unit which cost me 15$ to return -.-

Riprogrammato per renderlo hub zigbee funziona bene collegato con un Raspberry, il segnale non è il massimo

Funziona benissimo ma il segnale è basso. Con un muro in mezzo non arriva a 5 mt
