Frequently Asked Questions

Celsi is Australia's leading automated temperature monitoring system designed specifically for food businesses, restaurants, cafes, aged care facilities, and food processing operations. Unlike manual temperature logging, Celsi uses wireless IoT sensors that continuously monitor your fridges, freezers, and storage areas 24/7. When temperatures go outside safe ranges, you receive instant alerts via SMS, email, or WhatsApp. The system automatically generates HACCP-compliant reports for health inspections and audits, eliminating the need for manual temperature checks and paperwork.

Manual temperature logging requires staff to check and record temperatures multiple times daily, which is time-consuming, prone to human error, and leaves gaps in coverage overnight and during busy periods. Celsi provides continuous 24/7 automated monitoring with real-time alerts, meaning you're immediately notified if something goes wrong—even at 2 AM when nobody is in the kitchen. This prevents food spoilage, ensures constant HACCP compliance, and saves staff hours every week by eliminating manual checks and paperwork.

Celsi is used by restaurants, cafes, butcher shops, bakeries, food trucks, catering companies, aged care facilities, hospitals, schools, universities, food processing plants, cold storage warehouses, laboratories, pharmaceutical facilities, and any business that needs to maintain temperature-controlled environments. Our system is particularly popular with multi-location restaurant chains and aged care facilities that need centralized monitoring across multiple sites.

Most Celsi installations are completed in 1-2 hours. Our wireless sensors don't require any electrical work or hardwiring—they simply stick to your fridges and freezers using industrial adhesive or magnets. The hub plugs into power and connects to your internet, and you're monitoring temperatures within minutes. We provide free installation support and can have you up and running the same day you receive your equipment.

Celsi offers over 25 different sensor types beyond just temperature monitoring. Our temperature sensors range from -200°C to +300°C, suitable for everything from ultra-low freezers to commercial ovens. We also provide humidity sensors for dry storage monitoring, door sensors to track cool room access, motion sensors (PIR) for security, CO2 sensors for indoor air quality, water leak sensors, light sensors, and people counting sensors. This makes Celsi a comprehensive environmental monitoring solution, not just temperature logging.

Celsi sensors use long-life industrial batteries that typically last 2-5 years depending on the sensor type and reporting frequency. Unlike competitors' sensors that need battery replacement every 3-6 months, our sensors are designed for minimal maintenance. When a battery does need replacement, the sensor swap is included as part of your service—we send you a replacement sensor at no additional cost, making Celsi a truly hassle-free solution with predictable costs.

Celsi's hub requires internet connectivity to send alerts and sync data to the cloud. However, the sensors continue to log temperature data locally during internet outages, and this data automatically syncs when connectivity is restored, ensuring you never lose temperature records. For critical applications, we recommend having a backup internet connection (4G hotspot) or using our optional cellular-enabled hub that doesn't rely on WiFi.

Yes, Celsi offers a comprehensive REST API that allows integration with property management systems, facility management software, building management systems (BMS), and custom applications. We have pre-built integrations with Tanda (staff rostering), Restoke.AI (inventory management), and various POS systems. Our API provides real-time access to temperature data, alerts, and reports. We also support webhooks for event-driven integrations and can export data to third-party analytics platforms.

Celsi sensors are industrial-grade and highly reliable, but if a sensor does fail or loses connection, you'll receive an immediate notification. As part of your subscription, sensor replacement is included at no extra cost—we'll ship you a replacement sensor overnight. This is a key advantage over competitors who charge for replacement sensors or require you to maintain spare inventory. We also monitor sensor health proactively and will notify you before a battery runs low.

Yes, Celsi is fully HACCP (Hazard Analysis Critical Control Point) compliant and meets all Australian food safety standards including FSANZ (Food Standards Australia New Zealand) requirements. Our system automatically generates audit-ready temperature logs with time-stamped data that cannot be altered or deleted, meeting the documentation requirements for HACCP critical control points. Many health inspectors and auditors prefer automated monitoring over manual logs because it eliminates gaps and human error.

Absolutely. Celsi meets all Australian Aged Care Quality and Safety Commission (ACQSC) standards for food safety and medication storage monitoring. Our system addresses ACQSC Standard 1 (Consumer Dignity), Standard 3 (Personal Care), Standard 6 (Feedback & Complaints), and Standard 8 (Organisational Governance) by providing continuous monitoring, proactive alerts, and comprehensive documentation. Many aged care facilities use Celsi to monitor both food storage and medication refrigerators.

Celsi stores all temperature data indefinitely with unlimited history at no additional cost. You can access temperature records from years ago if needed for audits, legal disputes, or insurance claims. This is a major advantage over competitors who limit data retention to 90 days or charge extra for historical data access. All data is stored securely in Australian data centers with redundant backups and 256-bit encryption.

Yes, you can instantly generate and share compliance reports during health inspections or HACCP audits. Celsi provides PDF exports, email sharing, and even read-only guest access links that inspectors can view on their own devices. Our reports show continuous temperature monitoring with time-stamped data, alerts, and corrective actions taken, which often exceeds what manual logging can demonstrate. Many customers report that health inspectors are impressed with the comprehensive automated documentation.

For food safety compliance in Australia, cold food must be stored at 5°C or below, and frozen food at -18°C or below. Hot food for service should be kept above 60°C. Celsi allows you to set custom temperature thresholds for each sensor based on your specific requirements and food types. For example, you might set stricter limits (2-4°C) for high-risk foods like seafood, or specialized ranges for chocolate storage (15-18°C) or wine cellars (12-14°C). Our system alerts you immediately when temperatures drift outside your defined safe zones.

Celsi sends instant alerts via multiple channels when temperatures exceed your defined thresholds. You can receive notifications via SMS (text message), email, push notifications through the mobile app, and WhatsApp messages. Alerts are sent immediately—typically within 1-2 minutes of a temperature breach—giving you time to take corrective action before food spoilage occurs. You can configure different alert recipients for different times (day shift vs night shift), set escalation rules, and create alert schedules for holidays and weekends.

Yes, Celsi supports unlimited users at no extra cost, and you can configure custom alert routing. For example, kitchen staff might receive fridge alerts during business hours, while the manager receives all alerts overnight and on weekends. You can set up escalation chains where if an alert isn't acknowledged within a certain timeframe, it automatically notifies the next person in the chain. Multi-location businesses can configure alerts by site, ensuring each location's team only receives relevant notifications.

Celsi alerts are triggered by several conditions: temperature exceeding your defined min/max thresholds, rapid temperature changes that indicate equipment malfunction, sensor disconnection or battery low warnings, door sensors detecting a fridge left open beyond a set time, and humidity levels outside safe ranges for dry storage. You have complete control over alert thresholds and can set different rules for different sensors. For example, a walk-in freezer might allow brief temperature spikes during restocking, while a vaccine refrigerator has strict limits.

Yes, Celsi provides mobile apps for iOS and Android, as well as a web dashboard accessible from any browser. You can check current temperatures, view historical data, acknowledge alerts, generate reports, and manage settings from anywhere with internet access. This is particularly valuable for business owners who want to monitor their operations while away, facilities managers overseeing multiple locations, and on-call staff who need remote visibility into temperature conditions 24/7.

Yes, when you receive an alert, you can acknowledge it through the app or web dashboard to confirm you're aware of the issue and taking action. This stops further alert notifications for that incident while still logging the event. You can also add notes documenting what corrective action was taken (e.g., 'Technician called, fridge repaired'), which becomes part of your audit trail. There's also a planned maintenance mode that temporarily suppresses alerts when you're intentionally servicing equipment or defrosting units.

Celsi starts at $129 per month for our Starter plan, which includes 5 sensors, 1 hub, unlimited users, unlimited data storage, unlimited alerts, and free sensor replacements. Our Medium plan is $183/month with 10 sensors and 2 hubs, ideal for mid-sized restaurants. For chains and enterprise customers, we offer custom pricing with volume discounts. There are no per-user fees, no data caps, and no hidden costs. Sensor replacement, software updates, and Australian-based support are all included in your monthly subscription.

We're confident you won't want to cancel once you see how much time and stress Celsi saves.

Yes, we offer volume discounts for multi-location businesses, restaurant chains, and enterprise customers with more than 5 locations. We also provide special pricing for non-profit organizations, community services, schools, and registered charities. Contact our sales team at 1300 068 198 or through our demo page to discuss custom pricing for your specific needs. We're committed to making professional temperature monitoring affordable for organizations of all sizes.

No, Celsi is completely wireless and requires no electrical work. Sensors attach to your fridges and freezers using industrial-grade adhesive pads or magnets—no drilling or wiring required. The hub simply plugs into a standard power outlet and connects to your WiFi network. Most customers complete installation themselves in under an hour by following our simple setup guide. We also provide video tutorials, phone support during installation, and can arrange professional installation if preferred.

Celsi requires a standard internet connection with at least 1 Mbps upload speed—typical home broadband or business internet is more than sufficient. The hub connects via WiFi (2.4GHz or 5GHz) or Ethernet cable. Celsi uses minimal bandwidth (approximately 10-50MB per month), so it won't impact your internet performance. For locations without reliable WiFi, we offer an optional 4G cellular hub that uses mobile data networks instead, ensuring connectivity even in remote areas or locations with poor internet.

Celsi provides Australian-based customer support via phone (1300 068 198), email, and live chat during business hours. Unlike overseas call centers, our support team understands Australian food safety regulations, HACCP requirements, and local business needs. We also provide comprehensive online documentation, video tutorials, and a knowledge base. For enterprise customers, we offer dedicated account managers and priority support. Most questions are answered within minutes, and technical issues are typically resolved the same day.

Yes, Celsi sensors are specifically designed for commercial cool rooms and walk-in freezers with temperature ranges from -200°C to +300°C. Our sensors operate reliably in extreme cold conditions where many consumer-grade monitors fail. For metal-walled cool rooms that can block wireless signals, we recommend placing the hub nearby or using a wireless repeater to ensure strong connectivity. We also offer door sensors for cool rooms that alert you if doors are left open, preventing temperature loss and wasted energy.

Celsi sensors have built-in batteries and continue monitoring temperatures during power outages. However, the hub requires power to send alerts and sync data to the cloud. If power is lost, you'll receive a notification that the hub is offline. Once power is restored, all temperature data logged by sensors during the outage automatically syncs to the cloud, ensuring no data loss. For critical applications, we recommend connecting the hub to an uninterruptible power supply (UPS) for continued alerting during brief power interruptions.

While Clever Logger offers basic temperature monitoring, Celsi provides a more comprehensive solution with 25+ sensor types (not just temperature), longer battery life (2-5 years vs 3-6 months), included sensor replacements (Clever Logger charges for new sensors), unlimited data history (Clever Logger limits historical data), and broader integration capabilities including WhatsApp alerts and API access. Celsi also offers better Australian support and more competitive pricing for multi-location businesses.

SafetyCulture is primarily a digital checklist and inspection platform that still requires manual temperature entry—it doesn't provide automated monitoring. Celsi eliminates manual checks entirely with 24/7 sensor-based monitoring and instant alerts. While SafetyCulture is excellent for general compliance documentation, it's not a temperature monitoring solution. Many businesses use both: Celsi for automated temperature monitoring and SafetyCulture for other food safety checklists and inspections.

Yes, dramatically better. Manual logging apps (like Safe Food Pro, Squizify, or Chomp) still require staff to physically check and record temperatures multiple times daily, which is time-consuming, creates coverage gaps overnight and on weekends, is prone to human error or forgotten checks, and provides no real-time protection against equipment failures. Celsi's automated monitoring works 24/7, catches problems immediately, saves hours of staff time weekly, and provides more reliable data for audits. The difference is like comparing a smoke detector to having someone check for fires every few hours.

Consumer smart home sensors (like those from Amazon, Google, or Xiaomi) aren't designed for commercial food safety and have several limitations: they typically don't support HACCP-compliant reporting, lack proper calibration certificates, have limited temperature ranges unsuitable for commercial freezers, stop working during internet outages, don't provide audit trails required for health inspections, and lack professional support. Celsi is purpose-built for food safety compliance with industrial-grade sensors, regulatory-compliant reporting, and Australian food safety expertise.

Yes, Celsi is widely used by medical clinics, pharmacies, aged care facilities, and hospitals to monitor vaccine and medication refrigerators, particularly for COVID-19 vaccines and insulin that require strict temperature control (typically 2-8°C). Our system meets the Australian Immunisation Handbook requirements for continuous temperature monitoring of vaccine storage. The detailed temperature logs and instant alerts help maintain cold chain integrity and meet pharmaceutical compliance requirements, preventing costly medication losses due to temperature excursions.

Yes, Celsi is perfect for food trucks, mobile catering, and outdoor events. Our sensors work on battery power (no hardwiring needed), and the hub can connect via 4G mobile data if WiFi isn't available. Food truck operators use Celsi to monitor refrigeration during transport and service, ensuring compliance at markets, festivals, and events. The GPS-enabled hub option can also track location alongside temperature data, useful for mobile operations or delivery vehicles with temperature-controlled cargo.

Absolutely. Cold storage warehouses, food distributors, and logistics companies use Celsi to monitor large-scale refrigeration across multiple zones and buildings. Our system scales from single fridges to hundreds of sensors across warehouses, providing centralized visibility and zone-specific alerts. We integrate with warehouse management systems (WMS) via API, support multiple temperature zones for different product types, and provide data exports for customer reporting and compliance documentation required by major retail chains.

Yes, Celsi's user management system supports multi-tenant environments like commercial kitchens, shared food production facilities, and co-working spaces. You can create separate user groups where each tenant only sees and receives alerts for their own equipment, while facility management has visibility across all tenants. This is popular in ghost kitchens, food incubators, and commercial kitchen rental spaces where multiple businesses share refrigeration facilities.
