Chapter 2

Getting your credentials

Four details carry you through everything that follows. They live in the CampMatic app. Write them down — the next chapters keep referring to them as placeholders.

Look them up in the app

Sign in at campmatic.de/app and open the Status page of your device. The card MQTT Bridge (Home Assistant) holds everything you need. The password only appears once you click the eye icon.

What the app shows text 
Broker        campmatic.de
Port          8883        (encrypted)
Username      campmatic_<GERAETE_ID>
Password      ••••••••    (eye icon)
Topic prefix  campmatic/<GERAETE_ID>
These credentials do more than read
They do not just let you watch your heater, they let you operate it. Do not pass them on, and do not enter them anywhere you would not trust with that.

The device ID

Besides its display name your CampMatic carries a second, technical name. You need it exactly once — in the bridge configuration in chapter 4. You will find it on the same Status page in the app, in the Device Status block as Device ID.

App › Status › Device Status text 
Device Name   Grand California 003     <- display name
Device ID     grand-cali-003           <- this is the one you need
Do not mix them up
The device ID is neither your three-digit device number nor the display name. Copy it exactly as the app shows it — hyphens included, all lowercase. A typo here means not a single entity will appear in Home Assistant later on.

Placeholders used in this guide

Every example and every file uses placeholders in angle brackets. You replace them with your own values — and the brackets go away. So remote_username <MQTT_USER> becomes remote_username campmatic_003, not <campmatic_003>.

Placeholder reference text 
<GERAETE_ID>       your three-digit device number, e.g. 003
<NODE>             the device ID from above
<MQTT_USER>        username from the app
<MQTT_PASSWORT>    password from the app
<ENTITY>           name fragment assigned by Home Assistant — see chapter 5
<SLOT_…>           slot number of a Bluetooth sensor — see chapter 8
Before you move on
  • You know your device number and have noted username and password
  • You have copied the device ID exactly as shown in the app
