It’s not a secret that cc2652p based ZigBee sticks or so-called v4 ZigBee sticks are currently the most hyped. Modules based on the cc2652p chip have a strong signal amplifier and a PCB antenna with a transmission distance of about 700m, so you don’t really need an external antenna. These modules will replace and work much better than any cc2531 based ZigBee stick with an antenna. There are many ZigBee v4 sticks from different makers available out there, check Tindie, all of them have the common cc2652p chip and all of them mostly work the same way. Unfortunately, there were no modules that support wireless network communication. Yes I know there are some cc2652p modules with LAN capabilities but no ZigBee v4 sticks with ser2net over WIFI, so that you can connect the stick to a standard USB phone charger.
I decided to design a ZigBee stick v4.5 that supports seer2net, (wireless serial communication) and doesn’t need to be connected to a home automation hub via USB.
How is it possible?
I have added an ESP8266 ESP-01 Module to the v4 stick with an esp-link firmware. That’s it.
To enable ser2net communication in your zigbe2mqtt you have to add to the configuration.yaml following:
in case you don’t want to use the ser2net connection, you can still connect the dongle to your home automation hub via USB and add to the configuration.yaml the usual USB device:
Here is a result (it has an IPX antenna connector to connect an external antenna, but in most cases, you will not need it since the cc2652p works perfect with the PCB antenna)
and it’s available for purchase on Tindie: https://www.tindie.com/products/25380/
Optionally USB Type A Male Connector can be replaced with Micro-USB female connector.
To increase the transmission power of HailBee or almost any v4 Stick, you can add:
experimental: transmit_power: 5
to the configuration.yaml of your zigbe2mqtt
As a value for the transmission power you can set any number from this list: -20,-18,-15,-12,-10,-9,-6,-5,-3,0,1..5,14..20
Now you can connect your ZigBee devices to your Home Automation Hub through HailBee v4.5 Zigbee Coordinator wirelessly through ser2net.
