Windows

These instructions explain how to run Zigbee2MQTT on Windows.

TIP

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.

Install a USB-to-UART Bridge Virtual COM Port driver

In order to be able to communicate with your USB device over a virtual COM port, you might need a driver for your OS in order for it to be able to be found by your flashing software.

For CP210x based chipsets, there is a driver available at Silicon Labs' website.
For CC1352/CC2652/CC2538 based chipsets, have a look at FTDI chip's website for drivers.

Installing

Download and install Node.js 22 LTS from their website
Open up a Command prompt or Powershell from the Start menu (Powershell has prettier colors)
Verify Node.js was successfully installed
```
node --version
```
Install pnpm
```
npm install -g pnpm
pnpm --version
```
Choose a suitable directory for Zigbee2MQTT and copy all the files from the Zigbee2MQTT repository
- if you prefer to use git (which you should), just clone the whole repository
```
git clone --depth 1 https://github.com/Koenkk/zigbee2mqtt/
```
- otherwise use the green Clone or download button to download the zip archive, then extract it
Change to the newly created directory and install dependencies with pnpm:
```
pnpm i --frozen-lockfile
```

Starting Zigbee2MQTT

Now that we have setup everything correctly we can start Zigbee2MQTT. Change to the root directory of your installation and run the Zigbee2MQTT:

pnpm start

On first start, Zigbee2MQTT will start the onboarding on port 8080. Navigate to this board and configure accordingly. More information about onboarding.

Once the onboarding is completed, you will see something like:

Zigbee2MQTT:info 2019-10-18 10:56:22 PM Logging to directory: 'D:\Documents\GitHub\zigbee2mqtt\data\log\2019-10-18.22-56-22'
Zigbee2MQTT:info 2019-10-18 10:56:22 PM Starting Zigbee2MQTT version 1.6.0 (commit #e26ad2a)
Zigbee2MQTT:info 2019-10-18 10:56:22 PM Starting zigbee-shepherd
Zigbee2MQTT:info 2019-10-18 10:56:24 PM zigbee-shepherd started
Zigbee2MQTT:info 2019-10-18 10:56:24 PM Coordinator firmware version: '20190608'

Zigbee2MQTT can be stopped anytime by pressing CTRL + C and then confirming with Y.

ATTENTION

In case Zigbee2MQTT fails to start with USB adapter discovery error (No valid USB adapter found). Specify valid 'adapter' and 'port' in your configuration., we need to configure the serial section in the configuration.yaml.

First determine which COM port is assigned to your device:

Open up Start menu and start typing Device Manager
Expand Ports (COM & LPT)
Look for a node similar to USB Serial Device (COM4)

Device Manager

For the example above, we would use port: COM4 in the configuration.yaml. Next configure the serial section as described here.

Updating Zigbee2MQTT

It is recommended to back up the Zigbee2MQTT \data subdirectory before performing any modifications.

First, stop Zigbee2MQTT
Navigate to the directory where the Zigbee2MQTT repository was cloned to in the Installing step
Pull the latest content from the configured source
```
git pull
```
Update dependencies
```
pnpm i --frozen-lockfile
```
Restart Zigbee2MQTT
```
pnpm start
```

Below is a sample PowerShell script to run which will take care of:

Backing up the data directory
Updating Zigbee2MQTT
Restoring the data directory contents

The script will automatically check if node is running (in case Zigbee2MQTT is still running) and ask to close if it is. You will need to manually stop and restart it afterwards.

Ensure you update the relevant paths in the script to match your environment. By default, the script will target D:\ProgramData\zigbee2mqtt\ as the install folder and C:\Temp\ as the folder where to temporarily store the data folder backup

Run script from an elevated administrative PowerShell console

# Z2M must not be running
# This script will NOT re-start it

# Modify below paths as necessary
$z2mPath = "D:\ProgramData\zigbee2mqtt"
$backupPath = "C:\Temp"


# DO NOT MODIFY below this line
# ------------------------------------------------------------------------------
# Build paths
$z2mDataPath = Join-Path -Path $z2mPath -ChildPath 'data'
$z2mBackupPath = Join-Path -Path $backupPath -ChildPath 'z2mdata'

# Check if Z2M is running
if (Get-Process -Name "node" -ErrorAction SilentlyContinue) {
    # Found running instance of node, stop script
    "Node still running, please close first" | Write-Host -ForegroundColor Red
    pause
    return
}
else {
    # Continue!
    "Node not running, Zigbee2MQTT upgrade will continue" | Write-Host -ForegroundColor Green
}
# Change working directory to:
"Setting location to ""$($z2mPath)""" | Write-Host
Set-Location -Path $z2mPath
# Back up data directory:
"Backing up data subdirectory" | Write-Host
Copy-Item -Path $z2mDataPath -Destination $z2mBackupPath -Recurse
# Pull the latest release:
"Running ""git pull""" | Write-Host
& git pull
# Update dependencies:
"Running ""pnpm i --frozen-lockfile""" | Write-Host
& pnpm i --frozen-lockfile
# Restore backed-up data:
"Restore backed up data directory" | Write-Host
Copy-Item -Path "$($z2mBackupPath)\*" -Destination $z2mDataPath -Recurse -Force
# Delete back up folder:
"Delete backed up folder" | Write-Host
Remove-Item -Path $z2mBackupPath -Recurse
"Update completed!" | Write-Host -ForegroundColor Green
pause
