Frequently Asked Questions

Listed below are a series of questions and answers related to using the Cellular Machines Temperature Monitoring System. If you have a question about the system, using it, or are having an issue that cannot be solved through the information below or the information provided in the Installation and Operation User’s Manual, please contact us.


If a change or update to the system is released, how would I receive it?

Updates made to the control stations firmware are done remotely via an over-the-air (OTA) update, up to firmware version V5.12f. While the control stations firmware is being updated, it cannot be used until the update is complete. Additionally, the system may need to be reconfigured afterwards, including re-syncing wireless pods, entering sensor information, or performing a factory reset. Whenever firmware is updated, a notification email will be sent to the Temperature Monitoring System owners email address informing them of the update and the changes that have been made.

NOTE: In the event of a power outage during an OTA update, the control stations internal backup batteries will power the device. If the batteries are out of power, or if the control station becomes disconnected from the power supply, the update will fail and the current firmware will remain active.


Are any components of the Temperature Monitoring System able to be installed outdoors?

No components of the Temperature Monitoring System should be installed outdoors. The components are designed to be installed in controlled environments only. Installing any components outdoors or in areas that may expose them to hazardous materials may subject them to damage or failure. However, system components that require an outdoor installation can be outfitted for such conditions. To explore customization options and component outfitting, contact Anaren Customer Support.


Are any components of the Temperature Monitoring System able to be installed in conditions of extreme (high or low) temperatures?

Only the temperature sensor can be safely located in conditions of high or low temperatures. Neither the control station nor the wireless pod should be installed in such conditions. Environments with extreme temperatures may affect these components ability to function, and can damage or corrupt the hardware inside them.


Are any components of the Temperature Monitoring System able to be installed in conditions of high humidity?

Only the temperature sensor can be safely located in conditions of high humidity. Neither the control station nor the wireless pod should be installed in such conditions. Environments with high humidity may affect these components due to moisture build up inside them. If this occurs, it may risk damaging or corrupting the hardware inside these components.


Is there any way to turn the control station on and off?

The only means to completely remove power to the control station is by disconnecting it from the power supply. This will shut down the control station completely and prevent it from reverting to using its internal backup batteries to maintain power. If the control station is off, connecting it to the power supply will turn it on again.


If the control station loses power by becoming disconnected from the power supply, will all of its settings remain intact when it regains power?

Yes. Once the control station is on again, it will activate as it did during the initial installation, and will recognize its synced wireless pods and retain all of its parameters.


If city power is lost for a period of time and my control station has to operate on its internal backup batteries, how long will the batteries last before the control station loses power?

The control stations internal backup batteries have a lifespan of approximately 15-20 hours, and are not rechargeable. If the batteries runs out of power, or if the control stations Low Batt LED is on and an alarm is received indicating low battery power, contact Anaren Customer Support to arrange to have them replaced. If the control station has been operating on its internal backup batteries for an extended period of time and you wish to preserve its battery power, disconnect the control station from the power supply to shut off the control station.

NOTE: Shutting off the control station will shut down the rest of the system and its alarming functions. Do so at your own risk. If the control station is off, a note that it is off the air will be indicated on the cloud server, and an email notifying the system owner that the control station is off the air will be sent.


The power failed at my facility and the control station’s internal backup batteries ran out of power. What do I do?

Replacement batteries will need to be ordered for the control station. Contact Anaren Customer Support to purchase and arrange to have the control station equipped with new internal backup batteries. In general, in the event a power failure occurs and it is unlikely to return within a reasonable period of time, disconnect the control station from the power supply to shut off the device. This will stop the system from monitoring the equipment, but will preserve its internal backup battery power.


The batteries in my wireless pod have lost power. How do I replace them?

The wireless pod comes with four AAA 1.5V alkaline batteries, which have a battery life of approximately five years. To replace these batteries, unscrew the pods enclosure to open it, then replace the batteries with four new AAA alkaline batteries. For pods that operate in cold environments, it is recommended to use lithium batteries instead.


Although the wireless pod comes with four AAA 1.5V alkaline batteries that can be replaced, can I use rechargeable AAA 1.2V batteries in the pod instead?

Yes, rechargeable AAA 1.2V batteries can be used in the wireless pod. There will be little or no noticeable difference if rechargeable 1.2V batteries are used instead of 1.5V alkaline batteries. However, rechargeable 1.2V batteries may experience a steep decline in power once they near the end of their charge, and the lifespan may be shorter than that of an alkaline battery. If using rechargeable 1.2V batteries, it is recommended to change them immediately if a battery low alarm is detected to prevent the pod from losing power.


I would like to add additional wireless pods and/or temperature sensors to my Temperature Monitoring System. How many of these can I use?

Up to 16 wireless pods and/or temperature sensors may be connected to the control station, with a maximum of four sensors per pod. Additional pods can be added, or sensors can be added to existing pods by using a combiner.


I am attempting to sync an additional wireless pod to the control station but it is not connecting or giving me an error. What is the issue?

If a wireless pod is being synced to the control station, all pods connected to the system (not just the new pod) must be re-synced. A pod that is not re-synced will not be recognized by the control station. Otherwise, the pod may be too close to the control station and cannot properly connect; a distance of at least six feet must be between the pod and the control station. Additionally, the maximum number of pods that can be synced to one control station is 16. Any number beyond that will fail to sync to the control station.


I added a second temperature sensor to a wireless pod using a combiner, but it is not showing up on either my control station or the online user dashboard. Why can’t my system see this sensor?

In order for a control station to recognize an additional (not to be confused with replaced) temperature sensor connected through a combiner, the wireless pod must be re-synced to the control station. Otherwise, the new sensor will not be displayed on either the control station or the online user dashboard. Note that if this is done, all pods connected to the control station must be re-synced.


Why does a temperature sensor connected to my system have a high number with its name? My system does not include that many sensors.

A temperature sensor is assigned a default number based on the number of its associated wireless pod and the number of sensors connected to it. In 16-sensor maximum systems each pod is allocated specific numbers for their sensors, and the assigned number of the sensor does not necessarily appear in numerical order. Sensor names may be changed, so this impacts the default numbers given to new sensors only. However, these default numbers are always displayed on the Cellular Machines online user dashboard next to the sensor name field, regardless if the sensors name has been changed.


During my freezer’s defrost cycle, the temperature sensor inside the freezer gets wet. Is this okay, or will it affect the device?

A temperature sensors probe collecting moisture during a defrost cycle will not have any detrimental impact on it. The temperature probe is protected and designed to endure these types of conditions. However, if moisture collects and permanently freezes on the temperature probe, or the temperature probe is in standing water, that can affect its ability to accurately measure temperature. Temperature sensors should be checked regularly to ensure they are in proper working condition.


The sensor RSSI of my wireless pod is within the acceptable range but I am still having connectivity issues with the control station receiving data. What is the problem?

The signal reception of the control station may be poor. Check the cell signal of the control station on its scrolling status menu and verify it is in an acceptable range of two or three bars. One or no bars will result in little or no connection, and the control station may have to be moved to another location to improve its signal reception. Likewise, if a wireless pod is displaying too low of an RSSI, it may have to be relocated as well.


I don’t know what I should set my temperature thresholds to. Where can I receive information on recommended or required temperature limits for my equipment?

Check the equipment manufacturers website or user manual for information on recommended temperature limits and proper use of their equipment. For state and federal requirements on regulated temperatures for certain products and inventory, visit the Food and Drug Administration website at, or the website for the regulating agency of that particular industry.


I recently updated my temperature thresholds with the online user dashboard, so why do I not see them updated on the control station?

When updating parameters through the online user dashboard, the control station will update during its next scheduled logging interval. Check the frequency of the logging interval to determine when the parameters will be updated on the control station. The control station can immediately update parameters by forcing it to log a message to the cloud server. Steps to force a cloud server log are outlined in the Installation and Operation User’s Manual.


I am receiving a high/low temperature alarm on a daily basis, yet there is nothing wrong with my equipment. What is wrong with my temperature sensors?

It is unlikely that the temperature sensor itself is defective. Instead, a setting for the equipment in question may need adjustment, or the location of the sensor itself within the equipment. Logon to the online user dashboard, and view the data report of the equipment responsible for the alarm during the length of time this has occurred. Analyze the data for any patterns or consistencies that may help determine the exact cause for the alarm. Common instances of these patterns include certain days of the week, time of day, and frequency of equipment use. Daily defrost cycles or refrigerator temperatures settling overnight or during long periods without use are two such examples. These instances may provide insight into adjusting the settings of the system to reflect the conditions of the equipment during these times. Alternatively, if the sensor is located in an area prone to fluctuating temperatures (such as near a compressor or very close to a door), it may inaccurately measure the equipments temperature and should be relocated to a more centralized area. If the alarm issues are not the result from a system setting or location of the sensor, there may be a potential issue with the equipment itself.


I am receiving a high temperature alarm whenever I open a monitored freezer, yet there are no problems. How can I get around this issue so the sensor doesn’t trigger a false alarm?


Temperature sensors can sometimes react quickly to events (such as a door opening), resulting in unwanted alarms. This can be avoided by either adjusting the alarm delay time for the sensor that is detecting the temperature change, or by installing a dampener to the sensor. The sensor dampener provides a thermal buffer for the sensor, and slows the sensors response time to such temperature shifts.


I had an error message regarding one of my temperature sensors that was corrected, but the control station still says there is an issue. Why has it not corrected its status?

The communication between the wireless pod and the control station may take up to two minutes to be established based on their signal reception. If more than two minutes pass and the error status remains unchanged, check the original source of the issue to verify it has been corrected.


I received a high temperature alarm of 45° Fahrenheit. The temperature then dropped below the high threshold to 44° Fahrenheit, however the alarm has still not been cleared. Why is my system still detecting an alarm?

The Temperature Monitoring System includes an alarming hysteresis in order to mitigate continuous setting and clearing of incidental alarms when temperatures hover near a threshold. This hysteresis is set to 2° Fahrenheit or 1° Celsius. Whenever a temperature alarm is triggered, it will not be cleared until it is beyond the hysteresis of the temperature scale used. In this example, the temperature must drop to 43° Fahrenheit in order for the alarm to be cleared.


I recently had service done to a piece of equipment being monitored. After it was fixed, the Temperature Monitoring System does not work as it did before. What is wrong with the system?

When any monitored equipment is subject to an environmental change, either from service, maintenance, or any other means, the settings for that equipment should also be modified to reflect those changes. This will prevent unnecessarily alarms from being triggered and receiving false alerts. Likewise, after any monitored equipment undergoes a period of change, it is important to return its system settings to what they previously were afterwards, or adapt them to any updates the equipment has gone through. Not doing so may result in inaccurate temperature readings or alarms, or failure to detect a harmful condition.


Why did I not receive a text message alert when an alarm was detected?

The mobile phone number may have been entered incorrectly, or the settings for either receiving text message alarms or that particular alert type might not be enabled on the control station. Ensure all mobile phone numbers are properly entered on the control station, and verify the text message alert settings are configured to your liking through using the control stations menu options.


An alarm was triggered by one of the temperature sensors but the alarm buzzer did not sound. Why did this not happen?

Verify the control stations alarm buzzer is enabled through the main menu. Likewise, check if the control station is in silent mode. If the control station is in silent mode, it will override the alarm buzzer if it is enabled, and no sound will be made if an alarm is triggered.


I accidentally reset my control station to its factory configuration settings. Is there a way of restoring the parameters to what they were configured to?

No. System parameters will need to be manually configured again. However, the online user dashboard stores wireless pod settings, so when pods are re-synced to the control station they will be reconfigured automatically after the first logging interval.

NOTE: The online user dashboard will populate pod settings based on the order the pods are listed. It is recommended to re-sync pods in the same order as they originally were in so the pod settings will be applied to the same pod.


Is the online user dashboard mobile friendly?

Yes. The online user dashboard can be accessed from any browser and from a personal computer, tablet, or mobile phone.


I visited the online user dashboard to check the activity of my temperature sensors but no data is displayed. Why would this happen?

When a new Temperature Monitoring System is installed and activated, it may take up to one hour for the cloud server to receive temperature readings and status for the first time (reporting via graphs may take slightly longer). After this initial instance, the cloud server will update during every logging interval, any time an alarm is triggered, and whenever a text message alert is sent. Otherwise, verify the control station has the UDP logging function enabled. If this function is disabled, no information will be sent to the cloud server and it cannot be viewed through the online user dashboard.

My facility is located in an area with poor cellular reception and coverage, and as a result my control station has difficulty sending information to the cloud server. Are there any options to improve this?

Refer to the Installation and Operation User’s Manualfor installation guidance to help maximize cellular reception capabilities. If cellular reception is poor and cannot be helped through installation or device location, contact Anaren Customer Support to seek an alternative solution.


Is my data and alarming plan unlimited?

No. The Anaren monthly data plan is a flat rate for all packages and contains a sufficient amount of data and text message allowance to cover system operation. The differences in data plans are within the length of the plans contract. Data plans do not include any data or service capabilities for personal mobile phones. In the event a control station alarms at an unusually high rate, contact Anaren Customer Support to bring the systems performance in-line. In extreme cases, Anaren reserves the right to modify the systems settings to comply with reasonable data and text message usage policies. If Anarens solutions for modifying system settings due to extreme data and text message usage are ignored or bypassed, Anaren reserves the right to apply additional charges for text message and data overages.
