They track temperatures inside vaccine refrigerators, humidity in archive rooms, water levels in remote culverts, voltage on a solar installation, environmental conditions in laboratories, and equipment performance in manufacturing facilities. The monitoring works exactly as intended. The problem usually begins after an alarm is generated. A threshold is exceeded at 2 a.m., an email notification is sent, and the technician who needs to respond is asleep, off-site, or simply not watching their inbox. Data only has value when the right person sees it in time, and email isn’t always the fastest way to deliver urgent alerts. For years, many organizations relied on free carrier email-to-text gateways to forward those notifications as SMS messages. Most of those services have now been discontinued, leaving existing alert workflows without a dependable path to mobile phones. TextBolt replaces those retired carrier gateways with a [business-grade email-to-SMS gateway](https://textbolt.com/). It converts the alarm emails your HOBO monitoring system already sends into text messages delivered directly to the on-call technician, without custom development, new hardware, or an SMS API. In this guide, you’ll learn how HOBO data loggers generate alerts, what hardware and software options are available, and how to deliver alarm notifications as SMS using your existing email workflow. ## What is a HOBO Data Logger? A HOBO data logger is a battery-powered device that automatically records environmental conditions such as temperature, humidity, water level, light, and other sensor readings at scheduled intervals. It stores each reading with a timestamp, helping teams monitor conditions, maintain records, and identify issues before they become problems. Developed by [Onset Computer Corporation (now part of LI-COR Environmental)](https://www.onsetcomp.com/who-we-are/news-and-events/news/li-cor-environmental-acquires-onset-hobo-data-loggers), HOBO data loggers are widely used in cold storage, agriculture, research, buildings, laboratories, and remote monitoring. HOBO loggers come in three main types: - **MX Series:** Bluetooth-enabled models like the **HOBO MX2200 Series data loggers** and **Onset HOBO data loggers MX2202** that sync with phones, tablets, or MX Gateways. **HOBO MX multi-channel data loggers** support multiple sensors from one device. - **UX and U Series:** USB-based **HOBO temperature data loggers** such as the **UX100** and **UX90** that store readings locally and export data through HOBOware. - **RX Series:** Remote monitoring stations that upload data to HOBOlink or LI-COR Cloud through cellular, Wi-Fi, or Ethernet connections. Depending on the sensors attached, HOBO devices can measure temperature, humidity, CO₂, water level, pressure, dissolved oxygen, rainfall, wind speed, solar radiation, soil moisture, and more. ## How Do HOBO Data Loggers Work? HOBO data loggers follow a simple cycle: collect readings, store data, and send information to the platform used for monitoring. Users set a logging interval, such as every minute or every 15 minutes. The device records sensor readings with timestamps and transfers the data through the appropriate software or cloud platform: | **Logger Type** | **Platform** | **Data Access** | |---|---|---| | UX and U Series | HOBOware | Download readings through USB | | MX Series | HOBOconnect | Sync data wirelessly | | RX Series | LI-COR Cloud | View cloud data and alerts | The platform used depends on the hardware. - **USB-based HOBO temperature data loggers** such as the UX Series typically require manual downloads through HOBOware. - **Bluetooth HOBO data loggers** such as MX models can sync through the HOBOconnect app or transfer data automatically when paired with an MX Gateway. - **Remote HOBO stations** such as RX Series devices continuously send data to LI-COR Cloud, making them suitable for unattended monitoring and automated alerts. For alert-based monitoring, LI-COR Cloud is the key component because it allows users to create alarm rules and decide how notifications should be delivered. ## How LI-COR Cloud Sends Notifications From HOBO Data Loggers HOBO data loggers do not send text messages directly from the sensor. The logger first sends readings to the connected monitoring platform, where LI-COR Cloud checks the data against configured alarm settings. The notification workflow looks like this: **HOBO Data Logger → LI-COR Cloud (Evaluates Alarm Condition) → Notification → Phone or Inbox** The exact process depends on the HOBO system being used. ### RX Series Remote Monitoring Alerts HOBO RX Series stations, including models such as the RX3000 and MicroRX, connect directly to LI-COR Cloud using cellular, Wi-Fi, or Ethernet. The workflow is: **HOBO RX Station → LI-COR Cloud **(Evaluates Alarm Condition)** → Email or SMS Notification** Users configure alarm conditions inside LI-COR Cloud, such as: - Temperature moving above or below a safe range - Water level exceeding a limit - Battery reaching a low level - Station missing a scheduled connection When the condition occurs, LI-COR Cloud sends the notification using the selected method. ### MX Bluetooth Logger Alerts With MX Gateway Bluetooth-based HOBO MX loggers need an additional connection method to send data to the cloud. An HOBO MX Gateway collects readings from nearby MX loggers and transfers them to LI-COR Cloud through Wi-Fi or Ethernet. The workflow becomes: **HOBO MX Logger → Bluetooth → MX Gateway → LI-COR Cloud (Evaluates Alarm Condition** **→ Notification** For example, an Onset HOBO data logger MX2202 monitoring a refrigerator can send temperature readings to an MX Gateway. LI-COR Cloud then checks those readings against the configured alarm threshold and sends a notification when the condition is met. The MX Gateway does not create the alert itself. Its role is to move HOBO sensor data into LI-COR Cloud, where monitoring rules and notifications are managed. ## What are the Types of Alerts Send from HOBO Data Loggers LI-COR Cloud supports different types of alarms depending on what users need to monitor. ### Sensor Alarms Sensor alarms are triggered when measured values move outside the configured range. **Examples:** - Refrigerator temperature rises above the allowed limit - Humidity exceeds a defined threshold - Water level reaches a critical point Users can configure additional conditions, such as requiring several consecutive readings before triggering an alert. This helps reduce unnecessary notifications caused by temporary fluctuations. ### System Alarms System alarms monitor the health of the monitoring setup rather than environmental conditions. **Examples include:** - Low battery - Lost connection - Sensor failure - Communication problems - Device not reporting data These SMS/ text alerts help teams identify monitoring failures before they miss important environmental changes. ## How Does LI-COR Cloud Send HOBO Alarm Notifications? HOBO data loggers do not send text messages directly. They collect sensor readings and send the data to LI-COR Cloud (HOBOlink), where alarm rules are monitored. When a reading crosses a configured threshold, LI-COR Cloud triggers an alarm notification. For example, if an MX2202 temperature logger monitoring a vaccine refrigerator detects that the temperature rises above 8°C, LI-COR Cloud identifies the condition and creates an alert containing details such as: **Device:** MX2202 **Location:** Vaccine Storage Room **Current Reading:** 9.2°C **Threshold:** Above 8°C LI-COR Cloud can then send this alarm notification through the delivery method configured for that device or alarm rule. For many teams, the notification starts as an email because it works with existing workflows and can be routed to different systems. However, receiving an email is not always enough for time-sensitive events. A technician may not see an inbox notification immediately, especially during overnight temperature excursions, equipment failures, or remote site issues. This is where an [email-to-SMS gateway](https://textbolt.com/blog/email-to-sms/) helps. TextBolt uses the LI-COR Cloud alarm emails you already receive and converts them into SMS alerts, allowing critical notifications to reach the right person directly on their phone without changing your HOBO monitoring setup. The next section explains how TextBolt fits into the HOBO alert workflow and how it delivers these alarm notifications as text messages. ## How TextBolt Works With HOBO Data Logger Alerts TextBolt does not connect directly to HOBO sensors, MX Gateway hardware, or LI-COR Cloud APIs. Instead, it works as an email-to-SMS delivery layer between LI-COR Cloud and the phone receiving the alert. Many organizations previously used free carrier email-to-text gateways, such as Verizon’s @vtext.com and AT&T’s @txt.att.net, to forward HOBO alarm emails as SMS messages. These services provided a simple way to convert an email notification into a text, but carrier support for these legacy gateways has changed. [AT&T discontinued its email-to-text service,](https://textbolt.com/migration/att/) and [Verizon is retiring its vText and VZWPix gateways](https://textbolt.com/migration/verizon/), making them a less reliable option for automated monitoring alerts. TextBolt replaces this missing delivery step without requiring changes to your HOBO hardware or monitoring setup. The workflow becomes: **HOBO Data Logger → LI-COR Cloud → Alarm Email → TextBolt → SMS Alert** When LI-COR Cloud detects an alarm condition, such as a temperature threshold being exceeded, low battery warning, or lost connection, it sends the notification email to a TextBolt email-to-SMS address. TextBolt converts that email into an SMS message and delivers it directly to the assigned phone number. This approach allows teams to continue using their existing HOBO loggers, MX Gateways, RX stations, and alarm configurations while adding a more reliable email to SMS delivery path for critical notifications. Teams running [MadgeTech data loggers](https://textbolt.com/blog/madgetech-text-alerts/) alongside HOBO hardware use the same email-to-SMS pattern from a single TextBolt account. ## How to Connect HOBO Data Loggers With TextBolt Connecting HOBO alerts with TextBolt does not require code, API integration, or changes to your HOBO hardware. The setup happens by adding your TextBolt email-to-SMS address as a notification recipient inside your LI-COR Cloud alarm configuration ### Step 1: Create Your TextBolt Address After creating a TextBolt account, you receive a unique email-to-SMS address: **+1XXXXXXXXXX@sendemailtotext.com** This address acts as the destination for your LI-COR Cloud alarm emails. ### Step 2: Add TextBolt as a LI-COR Cloud Notification Recipient In LI-COR Cloud: 1. Open Devices and select the HOBO station or gateway you want to configure. 2. Open the device’s Alarm Configuration settings. 3. Create a new alarm or edit an existing sensor or system alarm. 4. Under the notification or action settings, select Email as the delivery method. 5. Add your TextBolt email-to-SMS address as the recipient. You can configure TextBolt for different LI-COR Cloud alarm types, including high or low temperature alerts, humidity threshold alerts, water level warnings, lost connection notifications, and low battery alerts. Multiple recipients can also be added to the same alarm, allowing different team members or on-call contacts to receive the notification at the same time. ### Step 3: Test the Email to SMS Alert Workflow Trigger a test alarm and confirm: 1. The HOBO logger records the condition. 2. LI-COR Cloud detects the alarm. 3. LI-COR Cloud sends the email notification. 4. TextBolt converts the email into an SMS. 5. The alert reaches the intended phone. After testing, every future alarm follows the same automated path: **HOBO Data Logger → LI-COR Cloud → Email → TextBolt → SMS Alert** **A Real Example: HOBO Temperature Alarm to SMS** A pharmacy uses an HOBO MX2202 temperature logger to monitor a vaccine refrigerator. The setup includes: - MX2202 temperature logger - MX Gateway - LI-COR Cloud monitoring - TextBolt SMS delivery The temperature threshold is configured: **Normal range:** Below 8°C **Alarm condition:** Above 8°C for multiple readings The workflow: MX2202 records temperature change ↓ MX Gateway transfers readings to LI-COR Cloud ↓ LI-COR Cloud detects the temperature alarm ↓ Alarm email is sent to TextBolt ↓ TextBolt delivers SMS to the pharmacist The response team receives the alert quickly and can take action before inventory is damaged. ## Things to Know Before Sending HOBO Alerts as SMS Text alerts make HOBO monitoring more responsive, but there are a few limitations to keep in mind: - Your HOBO system must have a way to send alerts through LI-COR Cloud, such as an RX station or an MX logger connected through an MX Gateway. - SMS messages contain text only and cannot include graphs, charts, or full monitoring reports. - TextBolt delivers SMS alerts to US and Canadian phone numbers. - If the logger cannot communicate with LI-COR Cloud because of connectivity or hardware issues, no notification service can send an alert. ## Make Sure Your Alerts From HOBO Data Logger at the Right Time to the Right Person Your HOBO stations already do the hard part. They watch the freezer through the night, catch an excursion the moment it starts, and log every reading without being asked. None of that protects anything if the alert dies in a shut-down carrier gateway and no one hears it until the loss is done. That last step, turning an alarm into a text someone actually receives, is all that stands between a caught problem and an expensive one. TextBolt restores it in minutes. Your LI-COR Cloud alarms keep firing exactly as they do today, each one arrives as a text within seconds, and every send is logged so you can prove it landed, with no new hardware and no code. The same setup carries any email-capable monitor, from [server-room temperature alerts](https://textbolt.com/use-case/server-monitoring-text-alerts/) to ServiceNow incident texts, so one fix covers your whole stack. If your loggers are still reporting but the texts have gone quiet, that gap is fixable today. Point your LI-COR Cloud alarms at a TextBolt address and put your critical alerts back where they belong, on the phone of the person who can act. Receive Your HOBO Alerts on the Phone, Not Just in the Inbox Connect your LI-COR Cloud alarm emails to TextBolt and deliver critical monitoring alerts as SMS messages within seconds.

A web-based station reaches the cloud on its own, while a Bluetooth logger needs an MX Gateway to get there. The text itself is sent by the cloud platform or an email-to-SMS service like TextBolt, not by the logger hardware. **Does HOBOlink support SMS alerts?** HOBOlink, now part of the LI-COR Cloud platform, does support SMS alerts, but the feature can sit in a paid tier and still relies on carrier delivery. Email alarms are typically included in the base service. Sending those email alarms to TextBolt is often a cheaper and more reliable way to get the same text. **Can I send HOBO alerts to multiple phones?** You can send HOBO alerts to multiple phones by adding more than one recipient to the alarm. Give each person their own TextBolt address and add them all to the alarm’s notification list. This is the recommended setup, since a single recipient is a single point of failure. **Do I need new HOBO hardware to use TextBolt?** You do not need new HOBO hardware to use TextBolt if your logger already reaches HOBOlink, because TextBolt works from the alarm email your system already sends. You only need added hardware when a Bluetooth logger has no gateway, in which case an MX Gateway connects it to the cloud. Web-based stations work with TextBolt as they are. **How much does a HOBO data logger cost?** HOBO data loggers cost from about $69 for a basic standalone unit to over $2,500 for a professional multi-channel weather station. Price depends mainly on the environment, the parameters measured, and whether data offloads over Bluetooth or USB. Web-enabled station kits, where alerting matters most, generally run from about $829 to $2,549. --- _View the original post at: [https://textbolt.com/blog/hobo-data-loggers-text-alerts/](https://textbolt.com/blog/hobo-data-loggers-text-alerts/)_ _Served as markdown by [Third Audience](https://github.com/third-audience) v3.6.1_ _Generated: 2026-08-04 12:44:18 UTC_
