Getting Started / Installation

Installation of pc2mqtt works a little different on windows vs linux.

Linux

1. Download the latest binary from the releases
2. Setup a systemd service running the binary on start
3. Thats it

Windows

For windows pc2mqtt uses the windows-service-wrapper.

1. Download the latest windows zip archive from the releases
2. Unzip it to a directory of your choice
3. In cmd run pc2mqtt.exe install and pc2mqtt.exe start to install and start it as a windows service

Explaination: wrapped.exe is the actual binary. pc2mqtt.exe is the windows service wrapper which installs the service using the xml config file. For more info have a look at the windows-service-wrapper.
