Home assistant yellow: no zigbee radio

Configuration Zigbee
1

Hi,

I have received my Home Assistant yellow today. Since i was using a Raspberry Pi CM4 including a HA instance i just decided to plug the module into the yellow and wished for the best.

It started and everything worked except for the internal zigbee gateway. Since the ttyAMA1 did not appear i figured it was not enabled in the config.txt. So i added dtoverlay=uart2 and restarted the yellow a few times. Now, the ttyAMA1 appears but it is not showing the zigbee coordinator. When i try to setup ZHA using ttyAMA1, 115200, HW dataflow control it fails and returns something like “could not connect to ZHA-device”. I have already a conbee II stick on ttyACM0 which is using deconz integration but i guess it should not influence this?

Any ideas?

I tried numerous ways to install firmware manually, eg. https://github.com/NabuCasa/universal-silabs-flasher.

However, no matter what guide i use i end up with the message “failed to probe running application type”.

Yea, that’s not the best idea. The build of HAOS for Yellow includes specific configuration options for the various devices on the Yellow board, including the M.2 PCIe slot, RTC, Zigbee module, etc…

You might have better luck performing a full backup of your existing HA system, and then restoring it to your Yellow running the Yellow edition of HAOS.

Aarh okay - that makes sense.

I have now followed your advice. Now it works like! Thanks

Glad to hear!

Resurrecting and old thread so I apologize. I have this same problem but I suspect it is because I’m also using an SPI controlled Z-Wave radio (the ZooZ LR 800) and I recall reading I can’t use both?

I cannot use HassOS because I do custom stuff that I want to keep on my Yellow setup (Z-Wave/MQTT some data collection from my solar panels, etc.) so am trying to find the way to do it myself. Since /dev/ttyAMA1 does not show up (the Z-Wave radio is on ttyAMA0) I suspect something is either not configured, configured incorrectly, or yeah it’s that I can’t use both radios at the same time.

Anyone have any thoughts? I’m going down this rabbit hole because I want to add some tract lighting to our home but haven’t found any Z-wave versions of the lights I’ve found. I’d like a way to control the white balance via Home Assistant otherwise I’d just wire up an internal Z-Wave wall switch and call it a day.

Are you using this Zooz module for Z-Wave?

Zooz 800 Series Z-Wave Long Range GPIO Module ZAC93 LR - The Smartest House

I have the Zooz 800 Series LR GPIO Module ZAC93 installed on my HA Yellow. I can use both the ZAC93 for Z-wave and the onboard Zigbee radio module at the same time running under HAOS.

My guess is that the HAOS Development Team has done some special tweaks to the version of Linux to take into account the HA Yellow board’s specific hardware configuration.

Just wanted to let you know that it is somehow possible for both the HA Yellow’s onboard Zigbee and the Zooz ZAC93 GPIO Z-WaveLR module to coexist. I wish I could offer you some technical suggestions… :thinking:

Ah cool yep that’s the Zooz module I’m using. That means yep I guess I just need to sort out what they are doing to make it work. My hunch is it has something to do with the Pi overlays and/or udev stuff but that’s just sort of a wild guess.
