-title: "OwnTracks with two MQTT brokers"
-description: "Setting up OwnTracks with 2 MQTT brokers bridged for use with the MQTT bridge for SmartThings."
-ha_category: Infrastructure
----
-
-I ([surge919](https://github.com/surge919)) successfully tied in [OwnTracks](http://owntracks.org/) to Home Assistant and [SmartThings](https://www.smartthings.com/) while using authentication for external access. The MQTT bridge doesn't support authentication so I set up 2 MQTT instances.
- 
-Here are the steps I performed. Hopefully it saves someone else some time.
- 
-It seems to be working pretty well but if anyone sees something incorrect in my configuration, please let me know. This is my first real interaction with MQTT.
- 
-Here's a summary of my setup:
- 
-Two Docker instances for MQTT
-
-- 1 for internal use (the MQTT bridge for SmartThings - no authentication)
-- 1 for external use (for OwnTracks - with authentication)
- 
-All Docker configuration files are on my NAS so the Docker containers can be destroyed without affecting my actual configuration files.
- 
-#### Docker setup for the Mosquitto internal instance. No authentication for use with the MQTT bridge.
-
-```bash
-$ docker run -ti -p 1883:1883  \
-    -v /volume1/data/mosquitto-int/config:/mqtt/config:ro \
-    -v /volume1/data/mosquitto-int/log:/mqtt/log \
-    -v /volume1/data/mosquitto-int/data/:/mqtt/data/ \
-    --name mosquitto-int -d toke/mosquitto
-```
-
-#### Docker setup for the mosquitto external instance. With authentication for use with Owntracks.
-
-```bash
-$ docker run -ti -p 1884:1883  \
-    -v /volume1/data/mosquitto-ext/config:/mqtt/config:ro \
-    -v /volume1/data/mosquitto-ext/log:/mqtt/log \
-    -v /volume1/data/mosquitto-ext/data/:/mqtt/data/ \
-    -v /volume1/data/mosquitto-ext/etc:/etc/mosquitto \
-    --name mosquitto-ext -d toke/mosquitto
-```
- 
-Here are the configuration files:
-
-`/volume1/data/mosquitto-int/config/mosquitto.conf`
- 
-```bash
-connection mosquitto-ext
-persistence_file mosquitto.db
-try_private true
-address 10.0.0.20:1884
-start_type automatic
-username test
-password test
-notifications true
-topic owntracks/# in
-log_type all
-log_dest file /mqtt/log/mqtt.log 
-log_facility 5
-```
- 
-`/volume1/data/mosquitto-ext/config/mosquitto.conf`
- 
-```bash
-connection mosquitto-int
-persistence_file mosquitto.db
-try_private true
-address 10.0.0.20:1883
-start_type automatic
-username test
-password test
-notifications true
-topic owntracks/# out
-log_type all
-log_dest file /mqtt/log/mqtt.log
-log_facility 5
-allow_anonymous false
-password_file /etc/mosquitto/pwfile
-```
- 
-Create a password for `mosquitto-ext`
- 
-```bash
-docker exec -it mosquitto-ext /bin/bash
-cd /etc/mosquitto/
-mosquitto_passwd -c /etc/mosquitto/pwfile <userID>
-```
- 
-### OwnTracks settings for Android
- 
-```bash
-Preferences / Connection / Mode - Private MQTT
- 
-Fill out
- Host
- Identification
- Security: TLS disabled
