The new 1.2 version of the standard adds several important new features that improve the battery life for security sensors to over seven years, standardize device pairing, and simplify installation and maintenance for consumers and installers alike. The new features should have a major impact on operational and device costs to service providers and quality of service to consumers. ZigBee HA 1.2 is an update to the industry’s leading standard that delivers new features and benefits improving the comfort, convenience, security and energy management of consumers and enabling new business models for service providers. Specifically, HA 1.2 provides expanded service offerings, enhanced consumer experience, more ways to control energy usage, enhanced functions for door locks and appliances, electrical measurement devices, and a wide variety of sensors for the home.
As not all device manufacturers follow the Zigbee standard, at times a device can be incorrectly classified. Some other Zigbee coordinator hardware may not support a firmware that is capable of Zigbee 3.0 at all but can still be fully functional and feature-complete for your needs. This is very common as many, if not most, Zigbee devices do not yet Zigbee 3.0. As a general rule, newer Zigbee coordinator hardware generally supports Zigbee 3.0 firmware and it is up to its manufacturer to make such firmware available for them.
Modifying the device type
Binding is a “target destination” in form of a device address or group ID, endpoint, and cluster. For example, binding a Zigbee device like a remote to a Zigbee lightbulb, switch or group of lightbulbs allows direct control of the “target” device from the “remote” Zigbee device, bypassing ZHA. This means that the remote can control the lightbulb/group of lightbulbs even when the Zigbee coordinator is not available. Binding is only supported between the same cluster, for example, “output cluster id 6” (on/off cluster) of a remote, can be only bound to an “input cluster id 6” on the target device – light, switch. You can change this using YAML configuration, but this only works if there’s no existing network.
The EZSP protocol requires a stable connection to the serial port. With ITEAD Sonoff ZBBridge connecting over the WiFi network it is expected to see NCP entered failed state. This is a normal part of the operation and indicates there was a drop in communication between ZHA and Sonoff bridge. Zigbee home automation technology uses Mesh-Networking, meaning it can cover a wide area at only 2.4 GHz frequency, its wireless range connects up to 70m indoors and 400m outdoors. It is equipped with an encrypted security system so you and your device are safe from hackers.

Regardless, note that the best practice recommendation is, however, not to change the Zigbee channel from default as not all Zigbee devices support all channels. If you have issues with overlapping frequencies, then it will generally be a better idea to just change Wi-Fi channels on your Wi-Fi Router or all your Wi-Fi Access Points instead. The general recommendation is to only use channels 15, 20, or 25 in order to avoid interoperability problems with Zigbee devices that are limited to only being compatible with the ZLL channels as well as lessen the chance of Wi-Fi networks interfering too much with the Zigbee network. Note that especially using Zigbee channels 11, 24, 25, or 26 on your Zigbee Coordinator could mean it will probably not be accessible to older devices as those Zigbee channels are commonly only supported by relatively modern Zigbee hardware devices with newer Zigbee firmware. ZHA component has the ability to automatically download and perform OTA (Over-The-Air) firmware updates of Zigbee devices if the OTA firmware provider source URL for updates is available.
If you are using Docker and can’t connect, you most likely need to forward your device from the host machine to the Docker instance. This can be achieved by adding the device mapping to the end of the startup string or ideally using Docker compose. On Linux hosts ZHA can fail to start during HA startup or restarts because the Zigbee USB device is being claimed by the host’s modemmanager service.

Acomprehensive certification and testing program is also available to ensure that there is full interoperability of all devices from any manufacturer. Already, 19 version 1.2 products have achieved certification. The ZigBee Alliance announced that the latest update to its Home Automation standard is now ready for product development. The Home Automation standard is one of several ZigBee application standards that provide flexible frameworks for designers of specific uses of the ZigBee wireless technology.
In such a case you may want to upgrade the firmware manually yourself. The ZHA integration allows you to connect many off-the-shelf Zigbee based devices directly to Home Assistant, using one of the many available Zigbee coordinators. Zigbee promises a host of conveniences from securing your door, checking your mailbox from your smartphone, to controlling your indoor temperature. The best part is the device can stay operational for up to five years using only a lithium-ion battery.

Now that more details are available on zigbee 3.0 and devices are starting to come to market, note that it will only combine the profiles previously based on zigbee pro addressing. That includes ZHA, ZLL, and zigbee green, but specifically does not include the Zigbee Smart Energy profile used in smart meters. Philips Hue bulbs/lights that have previously been paired/added to another bridge/gateway will not show up during search in ZHA to pair/add a Zigbee device.
There is also support for grouping of lights, switches, and fans (i.e. support for commanding device groups as entities). At least two entities must be added to a group before the group entity is created. As well as support for binding/unbinding (i.e. bind a remote to a lightbulb or group). They are a brand id forgotten about because they never used to work well at all.
Consistent with ZigBee’s practice and commitment to the highest quality, ZigBee Home Automation 1.2 underwent rigorous testing, and 19 products have already achieved Golden Unit status for compliance testing and certification purposes. Is the device hardware address which can be read from the Home Assistant UI when looking at Device info. From device info, you can find the by viewing the Zigbee device signature.
These ZHA Device Handlers for Home Assistant can thus be used to parse custom messages to and from Zigbee devices. The ZHA Device Handlers that are made can then be reused by all users in future versions of Home Assistant. You use routers to increase the number of Zigbee devices that can be used in a network. The total number of Zigbee devices that you have on a Zigbee network depends on a few things, but you should know that Zigbee coordinator hardware and firmware only plays a larger role in Zigbee networks with a lot of devices. More important is how many directly connected devices (“direct children”) versus how many routers are connected to your Zigbee coordinator. This is 32 direct children, but if your Zigbee coordinator hardware is powerful enough then you can still have hundreds of Zigbee devices connected through routers.
You can optionally change its name and add it to an area . You can search again to add another device, or you can go back to the list of added devices. Zigbee 3.0 support or not in zigpy, depends primarily on your Zigbee coordinator hardware and its firmware. Some Zigbee coordinator hardware supports Zigbee 3.0 but might be shipped with an older firmware which does not.
