Installation
Ready in 10 Minutes
One plug to the Truma, 12V power — that's all it takes. No soldering, no crimping, no cable routing.
The steps below describe the installation of the CampMatic Truma controller. CampMatic Guard is even simpler: connect 12 V or USB power — done. No Truma connection required.
1
Connect Heater
Plug 1 goes into the LinBUS socket of the Truma Combi — the only connection to the heater.
2
12V Power
The box only needs 12V. Tap conveniently from the CP Plus — or from any other 12V source in your camper.
3
Connect & Go
Place box in service compartment, connect via WiFi or 4G — done!
Place the box in a protected, dry area near the Truma heater — e.g. in the service compartment under the bench seat (VW Grand California) or a similar compartment.
Detailed installation & setup guide
Three Ways to Connect
WiFi, 4G or local — you decide
Via WiFi
GC_HW01 · CM_LC_01
Connect the WiFi box to a network — phone hotspot, campsite WiFi, LTE router or Starlink. Full access from anywhere in the world. Applies to the WiFi variants of CampMatic Truma and Guard.
Via 4G Cellular
GC_HW_GSM01 · CM_LC_GSM01
The 4G variant connects directly via the cellular network — no WiFi needed. Works with any SIM card, compatible with all European mobile carriers. Applies to CampMatic Truma GSM (GC_HW_GSM01) and CampMatic Guard GSM (CM_LC_GSM01).
Local Fallback AP
All variants
No network? No problem. The box automatically creates its own WiFi network. Connect directly and control the heater locally or read gas and battery levels. Applies to all CampMatic models — Truma and Guard.
Compatibility
Will it fit my camper?
The points below apply to the CampMatic Truma controller. CampMatic Guard runs in any camper with 12 V power — a Truma heater is not required.
Any camper with Truma Combi / Vario Heat & CP Plus
CampMatic works in any vehicle with a compatible Truma heater and CP Plus control panel (C4+). Tested in VW Grand California 600/680 among others.
Supported Truma Heaters
Truma Combi 4 (Diesel/Gas), Truma Combi 4E (Electric/Gas), Truma Combi 6 (Diesel/Gas), Truma Combi 6E (Electric/Gas), Truma Combi D 6 (Diesel), Truma Vario Heat (Gas).

Customer Reviews
What Our Users Say
"Brilliantly simple! Installation really took just 10 minutes. Now I pre-heat my Grand California before arriving at the campsite."
"The Telegram bot is amazing. My wife now also controls the heating — right from the chat. And the frost alert already saved us once."
"As a Home Assistant user, this is fantastic: MQTT integration works perfectly. Integrated the box into my smart home and built custom automations. Top product!"
"Works as described. Plug in, connect WiFi, done."
"We spent a week in the Alps at -12°C. Heated the GC remotely every morning before getting up. Absolute must-have for winter camping."
"Solid product. Clean build quality, good documentation."
"Does what it should. Temperature history is a nice bonus. Looking forward to the GSM version."
"I'm not technical at all and managed the installation myself. The app is super intuitive. Best camper upgrade I've made."
"Replaced my Truma iNet Box with this. Way better — faster, more reliable, and the Telegram notifications are brilliant."
"Top!"
"ioBroker integration running perfectly. OTA updates are a plus. This is how IoT products should work."
"The scheduling feature is exactly what we needed. Heating starts automatically before we arrive on Friday evenings."
"Had a question about the CP Plus firmware — support replied within an hour. Great product, great service."
"Works perfectly with my phone hotspot. Turn on hotspot, CampMatic connects automatically. Super easy."
"The 4G version is exactly what I was looking for. No WiFi, no hotspot fiddling — insert a SIM and it just works. I control the heating from the office now."
"Power consumption is truly minimal — even after two weeks in winter storage the battery is still full. Great product."
"I use an IoT SIM for under 2 EUR a month, works across Europe. Exactly the solution for campers without WiFi."
New — CampMatic Guard
Gas & onboard battery always in sight
With the new CampMatic Guard you get gas bottle level and onboard battery voltage live in the app — wherever you are. Automatic notification the moment gas runs low or battery voltage drops below your threshold. Also included in all CampMatic Truma models.
Enough gas for the barbecue weekend? Is the fridge still running while you are at the beach? Will the battery last off-grid? Guard knows — before you have to ask.
Gas bottle (Mopeka)
When you don't need to control a Truma heater but still want to know remotely how full your gas bottle is and how charged your onboard battery is. CampMatic Guard reads Mopeka and BM2 Bluetooth sensors and shows everything live in the app and via Telegram.
Onboard battery (BM2)
Works with off-the-shelf BM2 Bluetooth battery monitors. Multiple BM2 sensors supported in parallel — monitor auxiliary and starter battery simultaneously, for example.
24-hour history right in the app. Perfect for long winter storage or before your next trip.
Guard reads data from Mopeka (gas) and BM2 (battery) Bluetooth sensors. For gas we recommend Mopeka Pro Check (steel and aluminium bottles, fixed tanks). For the battery a standard BM2 monitor is enough — 1 to n sensors in parallel (e.g. auxiliary and starter battery). Both sensors are not included and must be purchased separately.
Also integrates with Home Assistant — via MQTT auto-discovery, just like the CampMatic heating controller.
Order CampMatic Guard — from €59
Works with any camper — no Truma heater needed. The CampMatic Truma boxes already include this monitoring.
