Don’t assume that. Electrorama does not charge much for their previous Zoe series of products today. And as a bonus you would get integrated PoE support if you do not go with their “Lite” version of Zoe2. Also, consider other stand-alone PoE solutions for a Raspberry Pi will alone set you back around $30.
CC1352P should have exact same performance as CC2652P according to Texas Instruments specs.
CC1352P feature multi-band so it supports some sub-1GHz frequencies in addition to the standard 2.4GHz frequency range for Zigbee so that makes it a slightly more expensive chip/module, (and the software we use do not support sub-1GHz frequencies because it is mostly used by commercial Zigbee Smart Energy devices), but you can still fully utilize its 2.4GHz frequency just like if it was a CC2652P based device.
I know the above is related to the WiFi connectivity of the Sonoff ZB Bridge, but do we already know about the connectivity performance E2E when using ITEAD’s new EFR32MG21 dongle?
Has that been well tested by someone?
I just have an IKEA Bulb explode a few days ago. I took it apart and found a capacitor burned in the mainboard. I decided to make use of the ZigBee module from the bulb so I de-soldered it from the mainboard it appear to be Trådfri ICC-A-1 Module
The following is what I have done so far
solder wires to the module on the pads swdiotms, swclktck, VDD, GND
Connect the wire to a jlink clone pcb I bought cheap from aliexpress
Solder wires to the module PB14, PB15, PA0 then connect it to a ttl serial to usb module
connect to the module from putty with 115200,n,8,1 it was connected after I short PA0 to GND then I presented wit boot loader screen. I then upload gbl file NCP_USW_115k2_F256_678_PB14-PB15-PA0.gbl via xmodem
at this poit everything look ok but I can not connect it via bellows
The goal is to build a new zigbee coordinator or gateway with the module and firmware available to the module. I just try it in my test instance of home assistant with ZHA integration and I manage to have it working in ZHA now. btw. I’m not really sure why I can not get information of the coordinator using bellows and also (I using docker to run home assistant) mapping usb serial /dev/ttyUSB0 to /dev/ttyUSB0 did not work in home assistant docker remap it to /dev/ttyUSB0:/dev/ttyACM0 working without knowing why.
I have an order in and plan to replace my ZBBridge with it. I dont have a ton of Zigbee devices so it wont be a hard migration.
ZBBridge has been working fine now for over a year, but thinking I want to go back to a stick connected to my NUC vs a seperate box sitting on wifi.
Yah, I also do not like a Zigbee gateway depending on a wifi connection to your home LAN.
I currently use the Sonoff ZBBridge now for a year or so and face little issues. Weird behaviors are rare, also bcs of following reasons:
My wifi router is pretty good and only about 4-5 meters away from the Sonoff Zigbee Bridge.
I have a number of Zigbee Mini Switches of Sonoff which also act as Zigbee repeaters
I standardised almost completely on Sonoff devices/sensors, and even modified a few if a particular sensor function doesn’t exist in the standard product line.
This really helps: do not mix too many different makes: the less the better (although they all claim they are Zigbee 3.0 compatible).
For instance, I have an old hard-wired alarm system in my house with door and window proximity switches fully integrated in the wood work. This is now hard-wired to a number of Sonoff Zigbee door sensors.
Practically all Sonoff Zigbee sensors in my house do not run on battery power anymore. Those I modified too and are hardwired powered with 3V DC from a power adapter plugged in mains.
I even have Sonoff Zigbee motion sensors at various places in the garden. Also there a 3V DC line is powering these sensors hard-wired.
The same “SM-011 V1.0” Zigbee radio modules by CoolKit Technologies is also used inside some Zigbee gateways/hubs like this popular ITead Sonoff ZBBridge and ZB-GW03 eWeLink Ethernet Zigbee Gateway sold by EACHEN and SmartWise, so could perhaps be that the same Zigbee Router firmware could maybe also be used on the SM-011 Zigbee module in all or some of those products as well?
PS: Have not tried this myself as I got rid of my ITead Sonoff ZBBridge because being WiFi-based it did not work any good as a remote Zigbee Coordinator, but might reconsider buying one if it worked as a Zigbee Router device that can be paired/joined and restarted/reset remotely via Tasmota and/or ESPHome. So that Tasmota/ESPHome is basically only used to initiate virtual join/pair button and restart/reset the device similar to a remote power-cycle it hangs.
