Top Story

Monnit Engineers are set to roll out firmware over-the-air (FOTA) updates for various Monnit Sensors over the next few months.

FOTA updates for Monnit Sensors provide remote, one-click scalability that can optimize performance, add new features, improve battery performance, refine connectivity, and deliver critical fixes. Managed seamlessly through iMonnit^®, these updates also eliminate manual maintenance and keep devices secure.

Here’s a preview of what’s coming your way through iMonnit^® Software as a Service (SaaS) to the following ALTA^® Wireless Sensors and ALTA and ALTA XL^® Gateways:

ALTA Sensors & Meters

All ALTA radios will receive an enhancement to improve overall radio connectivity stability in sub −10°C (14°F) environments. As the reference frequency changes, this firmware enhancement will better account for those changes and quickly stabilize the network connection.

We’ll continue to tune the radios in our factory before they go out, but our enhancement is a further step in the field for greater ALTA Wireless Sensor Network stability.

ALTA Differential Air Pressure Sensors

We recently released a maintenance update for ALTA Differential Air Pressure Sensors. The enhancement includes the ability to apply an offset calibration to the sensor.

The updated firmware, coupled with the updated iMonnit Software, allows you to compensate for drift that may occur over time due to natural aging, temperature, physical stress, or other environmental factors.

ALTA AC Current Meters

Following another customer’s request, we’re updating the data set for our single-phase ALTA Wireless AC Current Meters. We’ve added an instantaneous reading. This is in addition to the Minimum, Maximum, and Average AMP-root mean square (RMS) data set and the accumulated Amp-hours read during Heartbeats or at set reporting intervals.

ALTA Water Rope Sensors

Our ALTA Water Rope Sensors will receive an update to better handle on-the-ground conditions, where humidity changes and rope contamination can affect their water-detection trigger points. We’ve implemented a more dynamic algorithm that better ignores environmental factors that could cause unexpected readings.

ALTA & ALTA XL IoT Cellular Gateways

We also have a new ALTA and ALTA XL IoT Gateway firmware release ready. The key change in this release is the Ethernet interface process for protocols. DHCP was noted to be working too fast. It was cutting off early and not accounting for some routers’ latencies.

When you’d request a DHCP lease and receive an IP address for that router, it might take up to a minute to get the lease back. The IoT Gateways gave up after 30 seconds. To improve the ALTA and ALTA XL IoT Gateways’ Ethernet capabilities, we’ve expanded the DHCP timing and enabled them to work better with routers, thanks to direct feedback from customers.

FOTA = Better Sensor Tech

The best technology doesn’t just solve today’s challenges. It keeps getting better over time. Our ongoing FOTA enhancements demonstrate Monnit’s commitment to improving sensor performance, reliability, and usability based on real-world customer feedback. Keep an eye on iMonnit over the coming months as these enhancements roll out, helping your wireless monitoring solution perform better than ever.

The Out-of-Sight ROI of HVAC Sensors

Wireless HVAC sensors help reduce costs and prevent equipment failures

Commercial HVAC systems are among the most expensive assets to operate and maintain, yet many facilities still rely on reactive maintenance. Waiting for equipment to fail can mean higher utility bills, emergency repairs, unplanned downtime, and even costly water damage.

Our latest blog, “HVAC Monitoring ROI: How Sensors Can Save Commercial Building Owners,” explains why wireless sensors have become one of the highest-return investments for commercial facilities.

According to the U.S. Department of Energy’s Smart Energy Analytics Campaign, advanced building analytics can reduce commercial building energy consumption by an average of 29%. Deloitte also reports that predictive maintenance programs can reduce maintenance costs by 25–30% while minimizing unexpected equipment failures.

Wireless sensors provide 24/7 visibility into HVAC performance by monitoring:

Temperature and humidity
Differential air pressure
Motor current and vibration
Condensate leaks and water intrusion
Indoor air quality and CO₂ levels

Instead of waiting for complaints or breakdowns, facility teams receive alerts when operating conditions begin to drift outside acceptable limits, allowing maintenance to be scheduled before failures occur.

For Real Estate Investment Trusts (REITs), the financial benefits extend beyond maintenance savings and the monitoring solution value included in a property’s overall value. Wireless monitoring can help:

Lower operating expenses by reducing energy waste and unnecessary technician dispatches.
Increase Net Operating Income (NOI) through lower utility and maintenance costs, helping improve property valuation.
Protect capital assets by identifying equipment issues early and extending the life of chillers, rooftop units, and air handlers.
Improve tenant satisfaction through better comfort and indoor air quality while supporting ESG reporting initiatives.

In many cases, preventing just one major HVAC failure or water damage event can pay for an entire sensor deployment, and then some.

Learn how wireless HVAC monitoring helps reduce costs, protect valuable assets, and maximize the performance and profitability of commercial buildings.

How to Calibrate Wireless Temperature Sensors

ALTA wireless temperature sensor calibration for accurate readings

Calibrated sensors are the precursor to precise, reproducible measurement. Our calibration processes are essential to product quality, safety, and compliance.

Customers in many industries, including food services, pharmaceutical manufacturing, logistics, pest control, facility management, health care, and hospitality, depend on our temperature sensors for exact readings.

To ensure reliable performance and uptime, your ALTA Wireless Temperature Sensors arrive accurately calibrated against a National Institute of Standards and Technology (NIST)-certified temperature sensor at ±1% (±1°C or 1.8°F). With your additional calibration, you can achieve a greater accuracy of ±0.25°C (±0.45°F). We can also provide a one-time or recurring NIST-traceable calibration certification.

If you believe an ALTA Temperature Sensor reading is inaccurate, you can recalibrate it using iMonnit. We have a Monnit Knowledgebase video to walk you through the following calibration steps:
