Consider switching from z2m to zha

[lociii]

Pros:

• Everything managed in HomeAssistant
• No additional system (rpi / z2m) to run

Cons:

• NUC must be moved into the apartment or the zigbee dongle must be forwarded to the basement

Test to forward the Zigbee coordinator from a Pi Zero W to the NUC using usbip, see thread.

On the Pi Zero W (USB host) running latest Raspberry Pi OS

Get the USB ID of the coordinator device

lsusb
>> Bus 001 Device 002: ID 0451:16a8 Texas Instruments, Inc.

0451:16a8 is the ID we're looking for.

Set up usbip

Install usbip, load the kernel module and set it up to load on boot

sudo -s
apt-get install usbip
modprobe usbip_host
echo 'usbip_host' >> /etc/modules

Add a service definition to expose the device in /lib/systemd/system/usbipd.service

[Unit]
Description=usbip host daemon
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/usbipd -D
ExecStartPost=/bin/sh -c "/usr/sbin/usbip bind --$(/usr/sbin/usbip list -p -l | grep '#usbid=0451:16a8#' | cut '-d#' -f1)"
ExecStop=/bin/sh -c "/usr/sbin/usbip unbind --$(/usr/sbin/usbip list -p -l | grep '#usbid=0451:16a8#' | cut '-d#' -f1`); killall usbipd"

[Install]
WantedBy=multi-user.target

Make the service known, load and start it

sudo systemctl --system daemon-reload
sudo systemctl enable usbipd.service
sudo systemctl start usbipd.service

On the client

Set up usbip

On Ubuntu usbip is part of the generic tools package, install it and load the virtual USB host controller module

sudo -s
apt-get install linux-tools-generic -y
modprobe vhci-hcd
echo 'vhci-hcd' >> /etc/modules

Add a service definition to make the remote device available in /lib/systemd/system/usbip.service

[Unit]
Description=usbip client
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/sh -c "/usr/lib/linux-tools/$(uname -r)/usbip attach -r 10.10.10.10 -b $(/usr/lib/linux-tools/$(uname -r)/usbip list -r 10.10.10.10 | grep '0451:16a8' | cut -d: -f1)"

[Install]
WantedBy=multi-user.target

Replace 10.10.10.10 by your IP address and 0451:16a8 by the ID of your USB device

Make the service known, load and start it

sudo systemctl --system daemon-reload
sudo systemctl enable usbipd.service
sudo systemctl start usbipd.service

Switch done. Everything working as expected except for Philips outdoor motion sensor SML002. See https://github.com/zigpy/zigpy-cc/issues/57

[lociii]

ZHA light groups aren't working as well. Using HA light groups as a workaround.

[lociii]

Group control fixed in https://github.com/zigpy/zigpy-cc/issues/58 and waiting for release

@lociii Seen you posted in https://github.com/zigpy/zigpy-cc/issues/58 and got other alternative serial-over-network tips if don't want to move your NUC:

The first tip is to use ESP8266 with Jeelabs ESP-LINK firmware instead of a Pi Zero W. Function is same if can connect via serial:

1. https://github.com/jeelabs/esp-link

The second cutting-edge tip is to buy the new Sonoff ZBBridge and run Tasmota with its serial-bridge, it is an all-in-one device:

2. https://www.digiblur.com/2020/07/how-to-use-sonoff-zigbee-bridge-with.html 2b. https://www.youtube.com/watch?v=dC1AEyFhmnc

PS: Regarding your Bitron AV2010/32 wall thermostat, open new issue on -> https://github.com/zigpy/zha-device-handlers/issues PPS: Somewhat related issue posted here but that is not quite on-topic https://github.com/zigpy/zha-device-handlers/issues/357

[lociii]

Oh wow. Thanks @Hedda

I got USBIP running on a Pi 3 since a while and it's working like a charm. Will check out your other proposals nevertheless. However I'd prefer not to buy another zigbee coordinator as the CC26X2R1 I'm currently using was quite expensive :-) For the group support it's just a matter of time until @sanyatuning changes are published.

For the Bitron AV2010/32 I just didn't update the list. They're working flawlessly.

So the last thing that's not working yet, is the SML002 Philips outdoor motion sensor from https://github.com/zigpy/zigpy-cc/issues/57

Will all work out sooner or later. People are spending their spare time to make all of this work, so I will have to be calmly waiting :-)

[Hedda]

Cool! If you have the skill then you too can help with quirks for devices, checkout -> https://github.com/zigpy/zha-device-handlers

[lociii]

Based on the discussion in https://github.com/zigpy/zigpy-cc/issues/57 it seems like the Philips SML002 needs some changes either to zigpy-cc or zigpy core. At least with my amateur knowledge of how zigbee communicates, it cannot be fixed in a quirk. Even if I would love to help, this goes way beyond what I'm currently capable of :)

[lociii]

Group support merged into HA core master https://github.com/home-assistant/core/pull/39318

[lociii]

Switched now from zigpy-cc to zigpy-znp and everything is working properly!
