Using a 2nd Raspberry Pi with a Remote Zigbee stick CC2531

Installation
1

Hey guys!

It seems I cannot understand what I have to do to make this work! My HA runs in a Raspberry Pi 3 but I need to setup a 2nd Raspberry Pi in my garage to implement some Zigbee sensors around the area.

I bought:

  • Raspberry Pi Zero
  • SD card
  • CC2531 USB stick with an antenna (it already came flashed and ready for Zigbee!)
  • USB to Micro USB OTG cable to connect the USB stick to the Pi Zero Micro USB port.

I was trying to read these instructions: https://www.zigbee2mqtt.io/how_tos/how_to_connect_to_a_remote_adapter.html

But it talks about a ā€œWiFi-based Serial-to-IP bridgesā€. Some tutorials on the web talk about a serial to USB cable. I simply canā€™t understand that.

Can anybody please help me here?

You havenā€™t got the silicon labs device so the sentence

WiFi-based Serial-to-IP bridges are not recommended for Silicon Labs EZSP adapters as the serial protocol does not have enough fault-tolerance to handle packet loss or latency delays that can normally occur over WiFi connections.

So what is your concern?

3

I am actually looking for a tutorial or better instructions on how to do it. How can I flash ser2net or similar to my Raspberry Pi Zero? Do I install Raspbian/Raspberry Pi OS 1st then use the command line to install ser2net?

Did I buy everything that was necessary to do it?

4

You will need to install raspberry pi os then

apt install ser2net

I think you have everything :slight_smile:

Thank you! I will give it a try! :grinning:

Come back if you need more help.

Another route would be to run all of the zigbee2mqtt software on the 2nd rpi, install a MQTT server if you do not have one running and then use MQTT messages between your HA server and the zigbee2mqtt server:

Before starting make sure you have an MQTT broker installed on your system. There are many tutorials available on how to do this, example. Mosquitto is the recommended MQTT broker but others should also work fine.

And yesā€¦ I had to come back! :face_with_raised_eyebrow:

I am trying to go with the ser2net way.

First of all, I have tested my CC2531 dongle on my Home Assistant Raspberry Pi 3. It worked flawlessly with the Zigbee2MQTT Add-on.

Now letā€™s go to the issue! Since I need this dongle to be at a remote place, I have bought a Raspberry Pi Zero W. Then, I installed Raspberry Pi OS (the regular version), enabled SSH via SD card, and set up a Wi-Fi connection. Everything is all right and I can access the Pi Zero using Putty.

I plugged the dongle to a Micro USB OTG adapter and pluged everything to the Raspberry Pi Zero. The LED from the dongle stays ā€˜onā€™ for about a minute, then it turns off (I donā€™t know if this is a normal behaviour).

The main problem is that I canā€™t find the USB device. I tried:

ls -l /dev/ttyA*

I could not find any device named as ttyACM0. For some reason, it looks like the Pi is not recognizing the USB stick.

Any ideas of how I should proceed? :pensive:

9

Type dmesg immediately after plugging it in. This is the kernel log and it should report the new device name.

10

The easy way to install 2nd HASS on your 2nd RPI and sent info to your master HASS the data required. You can use the remote assistant plugin to connect both systems.

11

Bit hard to install ha in a zero. Not recommended at all.

I respectfully disagree. HA on a pi zero is not recommended.
The easy way is to do a bare metal installation of Zigbee2MQTT on the pi zero, and point it to the existing mqtt server.
2 things to consider :
you have to change the mqtt topic from zigbee2mqtt to e.g zigbee2mqtt2 or zigbee2mqttgarage, as you can not have 2 zigbee2mqtt instances using the same mqtt topic
you have to use another panid for the same reason.

Heā€™d still need to find the co-ordinator device, but yes this is certainly an equally valid way as ser2net.

upsā€¦ yeah sorryā€¦ did not read pi zero in the listā€¦ my bad

I tried that but I still canā€™t see anything.

Exactly. This is the problem right now. I just bought a new OTG cable. The one I am using is too cheap to work properly. The new one will arrive tomorrow. I will let you know.

What does lsusb show?

Are you sure that is all? And everything is plugged in?

Yes I am sure. But as I told before I am starting to think that the OTG adapter is malfunctioning.

My CC2631 has an USB-A port and the Raspberry Zero only has a micro USB port so I need an adapter that works.

What else can I plug in this micro USB port in order to test it?
