+#### SSL/TLS
+
+You may want to connect to a remote server, in which case it's a good idea to use an encrypted connection. If the server supports this, then you can supply the relevant config values for the [tls_set()](https://github.com/eclipse/paho.mqtt.python#tls_set) command.
+
+```yaml
+mqtt:
+  host: test.mosquitto.org
+  port: 8883
+  tls:
+    enabled: yes
+```
+
+You may need to supply a trusted CA certificate, as instructed on https://test.mosquitto.org/.
+
+```yaml
+mqtt:
+  host: test.mosquitto.org
+  port: 8883
+  tls:
+    enabled: yes
+    ca_certs: mosquitto.org.crt
+```
+
+Or you might want to use SSL/TLS but not verify the server's certificate (not recommended).
+
+```yaml
+mqtt:
+  host: test.mosquitto.org
+  port: 8883
+  tls:
+    enabled: yes
+    cert_reqs: CERT_NONE
+    insecure: yes
+```
+
 #### Temporary Set
 
 You may want to set the output to a given value for a certain amount of time. This can be done using the `/set_on_ms` and `/set_off_ms` topics. If an output is already set to that value, it will stay that value for the given amount of milliseconds and then switch to the opposite.
