Comparing the Best RV Pet Temperature Monitors

RVs can heat up pretty fast in the hot summer months if your air conditioning stops working. This can be deadly for your pets if you aren’t there to constantly monitor the temperatures inside your RV.

And since most of us can’t take our pets into football games (or restaurants or many of our other RV adventures), we need a way to remotely monitor the temperatures inside the RV.

Thus, RV Pet Temperature Monitors.

RV Pet Temperature Monitors protect your unattended pets from the dangers of high heat and even cold temperatures too. Also useful to protect the RV during winter from freezing pipes. Protect your RV pets!

Cellphone Based RV Temperature Monitors

Cellphone based systems have their own cellphone service to communicate with the temperature monitor’s manufacturer’s servers who then communicate with you. This means that the monitoring is location independent and not dependent on spotty campground WiFi.

Those RVers out boondocking in spotty cellphone coverage may have difficulties getting consistent alerts in cases of problems at the RV. However, most monitors transmit minimal data meaning that alerts may still get out in marginal cell coverage (kind of like how text messages can work at football games even if Facebook won’t because of the heavy data use).

Cell based RV pet temperature monitors may send you alerts for high or low temperatures or humidity via text, email, call, or smartphone application, depending on specific service and options.

Waggle RV PetSafety Pet Temperature Monitor

Waggle RV Pet Temperature Monitor
RV PetSafety Pet Temperature Monitor was designed specifically with the RV pet owner in mind.


  • Real-time updates on conditions through smartphone app
  • GPS tracking in case your RV is lost or stolen
  • Includes 1 year cell subscription when purchased from Amazon


  • Monthly subscription costs after first year
  • Fee for starting or stopping monthly subscriptions
  • Only one sensor and only monitors temperatures

Ideal For: Full-time RVers with pets that are regularly left alone for long periods while RVer is at work or on excursions during extreme temperatures (heat or cold). The GPS tracking is also an ideal feature for travel trailer owners as travel trailers are at a higher risk of being stolen than Class A or Class C RVs.

Currently, the annual plan is $120/year ($10/month) while the monthly plan is $15/month with $5 fees for every time you start or stop service, quickly running up the total cost for part-time or seasonal RVers.

MarCELL PRO Cellular Monitoring System with Water Sensor

MarCELL PRO Cellular Monitoring System with Water Sensor for temperature monitoring in your RV
The MarCELL cellular temperature monitors are more robust and intended for a greater variety of uses beyond simple RV pet temperature monitoring. Used by real estate professionals, HVAC monitoring, and server rooms, the MarCELL is tested in a variety of conditions. The water sensors, also known as SPucks, can be converted into a “normally open” dry contact which can be used to alert you to things like entry into a room (think thieves during storage).



  • Additional Flooding and Lost Power Alerts
  • Powered via 120V adapter or USB which lets you use 12V RV system
  • Can turn off monthly monitoring without fees, so long as you use it 4 months per year
  • Can add additional water sensors to detect possible flooding issues


  • Monthly subscription costs
  • No GPS tracking for the RV
  • Only one temperature/humidity sensor

Ideal For: Full-time or part-time RVers that will leave their pets unattended in the RV and are also worried about potential flooding/pipe bursts and indoor humidity. With a less likely chance of being stolen, Class A and Class C RV owners may be less interested than travel trailer owners in the GPS tracking that the RV PetSafety monitor offers. Meanwhile, the option to convert SPucks into an entry alarm may be useful in case of thieves attempting to gain entry to steal the contents of your RV.

WiFi Based RV Pet Temperature Monitors

WiFi RV pet temperature monitors use a local wireless network to connect instead of a cell network. This means that you either need to be stationary or have a supplemental internet connection, like from a MiFi or other WiFi hotspot, like a second cell phone or cell activated tablet.

The benefit is that many people already have these, meaning no additional monthly fees for monitoring the RV conditions, even when away from home. With the limited data transferred, you won’t use up limited hotspot bandwidth for the limited hours that most RV tailgaters need the monitoring for (during the game).

Unfortunately, the WiFi temperature monitoring systems typically will not work with RV campground WiFi systems or those that require web browser login.

Without the cell phone connections, the WiFi temperature monitors typically have longer battery life, with each lasting over a year. The sensors typically have user replaceable batteries, either AA or watch style batteries commonly found in grocery or big box stores (like Wal-Mart) or even pharmacies.

Most WiFi temperature monitor systems will send an alert when they lose contact with the internet. So while you may not have GPS tracking with these systems, you can be immediately alerted if the sensors, and thus the RV, move outside your WiFi network.

Smart Air Quality Monitor

The Amazon Air Quality Monitor works with your Ring Alarm Pro system to monitor temperature, humidity, carbon monoxide, and VOCs inside your RV (or home). Great dual purpose for carbon monoxide and temperature for both humans and pets.



  • Connects with the Ring Alarm Pro system
  • History by week, day, hour available on app
  • Easy setup.
  • Can add routines with Alexa-enabled devices when certain conditions met (temperature, humidity)


  • Needs Ring or Alexa apps to operate as part of the larger system.
  • No GPS tracking
  • Few RV-specific Alexa-enabled devices so far.

Ideal For: RVers that have Ring security system in their RV.

This is a great add-on to the Ring Alarm PRO RV security system. Easily integrate in with other Alexa-enabled devices to monitor not just temperature, but also different aspects of air quality and then create routines that can automatically start when certain conditions are reached (ie turn a heater on with a plug during winter, turn on a dehumidifier, etc).

Can also add the Flood and Freeze Sensor which is great for monitoring for potential burst pipes in winter or just regular old water and plumbing mishaps.

Highly recommend the Ring Alarm Pro system for remote monitoring, including cameras, and basic automation of the RV. The system itself does require subscription for most remote monitoring capabilities, but include its own cell-based connection.

“Other” RV Pet Temperature Monitors

There are quite a few weather stations and similar temperature monitors that can help in a pinch. However, these are generally not recommended for monitoring pets in your RV. They are better suited for monitoring conditions while the RV is in storage at your home between trips.

AcuRite Indoor Temperature and Humidity Station

AcuRite Temperature and Humidtiy Station for monitoring conditions in and around your RV
Leave one sensor inside the RV, one in the wetbay, and one in the fridge with the base station in your garage. Monitor temperatures to prevent freezing pipes during the winter. Cost effective solution to check temperatures without going into the RV. See basic information at a glance from inside your garage or home.



  • Three additional sensors each with their own displays
  • No subscription fees
  • Battery powered (AA and AAA)


  • Additional purchase required for offsite remote access to current conditions
  • No GPS tracking

      1. Thanks Kimberly! We also got a MarCEL PRO with the temp probe and works great!! We even use it for the freezer when the pets are with us!!

        1. I’ve been known to stick the temp sticks in the wet bay during winter so I can keep an eye on the temps there to make sure the pipes don’t freeze! Always looking for ways to make the most out of our gadgets in small spaces – multiple uses are the best!

  1. Thanks very much for the comparison!! We also went with the Marcell PRO a few weeks ago and its been awesome!! Love the ability to use the temp probe if we want more accurate readings and being able to view realtime temps whenever we want!

    1. You are welcome Jessica. Glad to hear the Marcell is working out great for you. I wouldn’t travel with my dog without a temperature monitor in the RV now that I know that they work so well. Especially in the South during the summer months.

  2. I love this Nimble Temperature Sensor! First, I had trouble setting monitor up, but tech support helped me with that. It has a built-in 4G cellular network that allows me to keep track of temperature and humidity within my rigs in real-time. The product’s built-in rechargeable battery was another intriguing attribute. I was pleased to see this inclusion because it’ll ensure the device remains usable even during power outages. As for its notification process, this cellular pet monitor will send out alerts via text and email whenever the temperature rises or drops below predetermined limits.

  3. We have a Class B camper van and take our Great Dane and Lab. We are now able to walk them in the am and leave them without worry. This Nimble RV pet temperature monitor works better than I expected. I receive messages on my phone and apple watch to alert me if power crashes or if the temp is higher than what I program for alerts.
