Hi, i’m new to HA and really confused by using Zigbee for several sensors and automation tasks, and hope someone could help me to understand it better.
I bought an Sonoff and Xiaomi Temp-Sensor and thought imcould easily integrate them with a cheap CC2351 stick, bad mistake…
So i think i need to learn the principles of all that stuff. I read about several solutions, hubs, routers and brands and now i really don’t know what to buy.
What is needed to habe a good, expandable wireless network for using Zigbee devices?
Of what i read, the Zigbee 3.0 standard should be,preferred to be as much compatible as possible. Which device should be used to start with it? How to extend range of the communication? I have a house with a celler (here my Raspi for HA is located) a ground and a first floor, also a roof floor for storing things. I like to add actors and sensors everywhere for measuring temperature/humidity. Control lights, radiators, window rolls and such. Nothing unusual, nothing new, i think :]
Yes it is cheap, but it’s good, used one myself for 2 years until it died (using a Conbee II now, which i kind of regret, as it doesn’t support tcp2ser, and because of that i had to change from HyperV to VMware, but that is besides the point)
Back to CC2531…you need to set it up and flash it with the correct firmware, which can be a bit tricky…
When I compare Conbee II vs CC2531 performance, i can’t tell the difference, the switch went without any issues either (besides the HyperV issue, but that wasn’t really related to Zigbee)
I’m also a newbie and use HA + ConBee II + multiple zigbee devices.
The appropriately selected integrations (mostly) work very well out of the box. Eg; Onvif/MotionEye, Heiman/Siren, Aqara door and motion sensors, etc.
I’d also recommend reading a bit about the zigbee standard, and how it creates a network so your (non-battery mains powered) devices don’t talk directly to your hub (eg; RPI-4) but instead talk to each other. This creates an easily extended network from eg; sensor to sensor.
I wonder that i simply put the stick into my RP4, restarted it, install the add-on “ZHA” which directly detected the device. I bought the stick at Amazon and the offer tells “Firmware des Sticks ist die aktuelle CC2531ZNP-Prod.hex (19.06.2019)”
Next i could find my Xiaomi Aqara after activating the pairing mode
It seems that i was lucky that the firmware on my CC stick was more recent that stated in the offer. I now bound two devices without an issue, one Sonoff and one Xiaomi. I only find it hard to tell wheather or not a sensor is still able to connect an router/concentrator. I see that some devices may have a sensor for RSSI, but the both i use do not. How can i tell if they are still in good range?
My next step in using Zigbee would be to find a way to expand the range of my Zigbee wireless network. Currently one sensor could not be reached where i like to place it. What kind of devices would be best to also get this into range? I guess something in the middle of both, but maybe more “hops” are needed? I’ve read about lamps and switches acting as routers, but what should i use? My fear is to run into compatibility problems, as when i use a device from a vendor, it may only be able to forward traffic for this vendors devices and not for others? So i like to have somewhat “universal router devices” i guess.
CC2530/CC2531 USB stick, module, or dev board hardware flashed with Z-Stack coordinator firmware (no longer recommended as uses deprecated hardware and very old end-of-life firmware (because Texas Instruments stopped maintaining the SDK software development kit for it since several years back), plus will not work properly at all if the whole Zigbee network has more than 15-20 devices)
Thanks for all the good and valuable advises!
Gosh, first i would have bought that Sonoff stick but then i changed my mind because i thought it might be too tied to Sonoff-products and so i choose the CC2531 one… what a bad mistake
