Etabox allows you to remotely control boat heating, air conditioning, temperature monitoring and other devices from your phone. Start the heater before arriving at the harbour, monitor boat temperature in real-time and receive alerts directly to your phone.
Monitor boat temperature in real-time – get an alert if there is a freezing risk.
Track battery voltage remotely and set alert limits.
Start Webasto or Eberspächer before arriving at the harbour.
Control bilge pump or other 12V devices remotely.
Built-in IoT modem and SIM card – no separate router needed.
Etabox GPS model includes real-time boat location on a map.
Etabox is excellent for remote control of Webasto, Eberspächer and other diesel heaters on a boat.
Some heaters can be started directly from Etabox output with a small wake-up current without a separate relay. If needed, Etabox can also control a standard 12V relay for larger loads.
You can start the heater before arriving at the harbour so the boat is already warm when you get there.
Etabox includes two temperature sensors with 1.5 meter cables. Temperatures are displayed in real-time in the application.
For boaters, temperature monitoring is especially important during winter storage and early spring launches. You get an alert on your phone if:
You can set your own alert limits and notification texts.
Boat batteries can drain easily if devices are left on or charging fails. With Etabox you can monitor battery voltage remotely and set an alert if voltage drops too low.
This is especially useful when the boat is stored in winter or left unused for longer periods.
With OUT1, OUT2 and OUT3 outputs you can control various boat devices remotely:
The OUT4 potential-free solid-state relay can be used for more sensitive controls, such as simulating a button press.
Etabox does not require a separate WiFi connection. The device uses an internal IoT modem and operates with its own SIM card.
This makes Etabox ideal for boats – mobile network coverage is enough, no separate router needed.
Etabox operates at a supply voltage of 7V – 34V and is suitable for both 12V and 24V systems.
OUT1, OUT2 and OUT3 outputs provide the same supply voltage as Etabox is powered with.
Each output can handle a maximum load of 1A.
All outputs can be controlled by:
For example, heating can be started automatically before using the boat or ventilation can be scheduled to run during winter storage.
Etabox has no separate usage, application or cloud service fees. You only pay the SIM card subscription fees to your chosen operator.
The Etabox GPS model brings all standard Etabox features – remote control, temperature monitoring, scheduling and alerts – plus real-time GPS positioning.
GPS positioning on a boat is a practical feature: see the boat's location directly in the app at any time.
Etabox GPS is a particularly good choice for boats, where location tracking is useful for safety and storage monitoring.

One device – complete boat remote monitoring and control. No monthly fees, easy installation, Finnish quality.
