@ -109,6 +109,15 @@ There is an issue with the Mosquitto package included in Ubuntu 14.04 LTS. Speci
If you get this error `AttributeError: module 'ssl' has no attribute 'PROTOCOL_TLS'` then you need to set `tls_version: '1.2'`.

<p class='note'>
If you are running a Mosquitto instance on the same server as Home Assistant then you must ensure that the Mosquitto service starts before Home Assistant. For a Linux instance running Systemd (Raspberry Pi, Debian, Ubuntu and others) then you should edit the file /etc/systemd/system/home-assistant@homeassistant.service as root (e.g. sudo nano /etc/systemd/system/home-assistant@homeassistant.service) and add the mosquitto service:
```
[Unit]
Description=Home Assistant
After=network.target mosquitto.service
```
</p>
<p class='note'>
If you are running a Mosquitto instance on a different server with proper SSL encryption using a service like Let's Encrypt you may have to set the certificate to the operating systems own `.crt` certificates file. In the instance of Ubuntu this would be `certificate: /etc/ssl/certs/ca-certificates.crt`
