Thermo Cube
Remote temperature monitoring
with Thermo Cube
The Thermo Cube provides remote temperature monitoring at two measurement points. Its external probes connect to Polar Cloud through an integrated LTE gateway, so you can check readings when you are away.

What happens between temperature checks?
A reading taken on site tells you the temperature at that moment. Between visits, conditions can change, and a power interruption may affect cooling or ventilation as well as the equipment being monitored. Thermo Cube combines two external probes, LTE connectivity and a built-in battery to support remote temperature monitoring, helping your team check conditions and decide when action is needed.
See two measurement points
Monitor two locations with separate external probes. Compare conditions across storage zones or equipment areas to identify differences that a single reading could miss.
Place the probes where they matter
Each probe has a 5m cable, allowing the sensing points to be positioned separately from the enclosure and selected to suit your installation.
Battery backed cloud monitoring t
Built-in battery power supports the monitoring unit when mains power is unavailable. Combined with LTE connectivity, this helps your team maintain remote visibility when cooling or ventilation may also be affected.
Visibility that supports action
Monitor temperature readings, review trends and configure alerts in Polar Cloud to identify changes and optimise your operations. Where compatible controllers are connected, you can also configure automated responses and adjust operating settings through the Cloud, helping your team maintain suitable conditions and respond to temperature changes.

Where could Thermo Cube fit?
From cold storage and fresh produce handling to solar installations and battery rooms, temperature conditions can affect product quality and equipment performance. Thermo Cube gives you visibility at two measurement points, with readings, trends and configured alerts available through Polar Cloud.

Cold rooms, fridges and freezers
Monitor two storage zones and investigate temperature changes that could affect stock quality.

Packhouses and storage areas
Check conditions where fresh produce is held, packed or prepared for dispatch.

Solar, inverter and battery rooms
Monitor room temperatures around energy equipment and identify conditions that need closer attention.
See how it works in practice
Two measurement points can help you understand conditions where stock is stored and handled. These examples show how temperature visibility can support a practical response.
An industrial cold room or freezer
The two measurement points
An operator places one probe in a representative storage zone and the second in a separate zone where temperature may differ. The installer selects both positions within the reach of the two 5 m cables.
What can cause a change
A door left open, restricted airflow, a refrigeration fault or a power interruption can cause temperatures to move outside the required range.
What is at risk
Without visibility between checks, a change may go unnoticed while stock warms. Depending on the product and exposure, this can lead to quality loss, spoilage and stock write-offs.
How the team can respond
Thermo Cube sends both readings to Polar Cloud for remote checks. If one zone is warmer than expected, the team can inspect the door, airflow or refrigeration and decide whether stock needs to be moved.

Fresh produce in a farm pack house
The two measurement points
A farm monitors air temperature at two points: the fresh produce holding area and the ambient temperature of the packaging area. The readings help the team check conditions while produce is packed on the farm.
What can cause a change
Warm produce arriving from the field, loading delays, frequent door opening or tightly stacked crates can add heat or restrict cooling. Excessive cooling can also damage sensitive crops.
What is at risk
Unsuitable temperatures can shorten shelf life and reduce produce quality. Deterioration or chilling damage may lead to rejected loads and lost sales.
How the team can respond
The pack house team can check both readings in Polar Cloud and investigate conditions outside the range specified for the crop. Staff can then adjust handling, check cooling or move produce to suitable storage.

A battery room supporting solar and backup power
The two measurement points
One probe measures room temperature near the battery storage area. The second measures conditions at the other end of the room, near the inverter equipment. Probe positions should suit the airflow and the reach of the two 5m cables.
What can cause a change
Charging and discharging generate heat. High outdoor temperatures, restricted airflow or a cooling fault can also cause heat to build up unevenly across the room.
What is at risk
Sustained temperatures outside the equipment manufacturer’s recommended conditions can affect battery performance and accelerate ageing. Without visibility between visits, unsuitable conditions may persist before the team investigates.
How the team can respond
The team can compare both temperature readings in Polar Cloud, review trends and configure alerts against agreed operating limits. This helps them investigate cooling problems, review operating schedules and plan maintenance. Where compatible controllers are connected, configured Cloud actions can support an automated response.
Room-air monitoring complements the battery management system and the site’s protection systems; it does not measure individual cell temperatures or replace those systems.

Understand the essentials before planning an installation.
What is included in Thermo Cube?
The specified configuration includes two digital temperature probes with 5m cables, a PM-MB-T2 temperature interface, an LTE gateway, a mains power supply, a 12V 7Ah lithium battery and a wall-mounted enclosure. Antenna, mounting hardware and service inclusions will be confirmed with the product information.
What does remote temperature monitoring require?
Thermo Cube requires a suitable AC supply, cellular coverage, a managed cellular service and an active Polar Cloud account and licence. An internet-connected phone or PC is needed to view the readings remotely. Installation requirements and ongoing charges should be confirmed for your application.
Can I view trends or receive temperature alerts?
Polar Cloud supports trends and configured SMS/email alerts through the gateway platform. Available Thermo Cube features, alert settings and timing need to be confirmed for the proposed installation.
Does Thermo Cube control the temperature?
Thermo Cube is specified for monitoring. No relay or actuator outputs are included in the stated configuration.
Is a battery included?
A 12V 7Ah lithium battery is included. Backup duration and power switchover remain subject to final technical confirmation.
What warranty applies?
A 1 year warranty applies from the date of installation. The product must be correctly installed and activated on Polar Cloud, and form part of an active site with an active Polar Cloud licence.
