If you’re a full-time RVer with pets, you know the stress of leaving them behind in the rig, even for just a few hours. That’s where the MarCELL Pro Temperature Monitoring System shines. It’s an all-in-one solution for monitoring temperature, humidity, power outages, and even water leaks in your RV, giving you real-time updates right to your phone.

We’ve been using the MarCELL Pro for nearly six years, and we wouldn’t leave our pup — Sierra — behind without it.
The MarCELL is an all-in-one RV pet temperature monitoring system that can monitor temperature, humidity, power, and water. The device operates independently with a built-in cellular connection, so you don’t need to locate reliable WiFi.
There is a monthly fee to maintain the cellular service, and the initial cost of the unit is fairly expensive. However, for pet owners who want complete peace of mind when leaving their furry friend behind, the MarCELL just can’t be beaten.
Why Not Just Use Wi-Fi Pet Monitors?
Wi-Fi-based temperature monitors rely on a stable internet connection, which is something you rarely get at RV parks. Most park Wi-Fi systems are spotty, and many require you to reconnect manually every few hours.
For that reason alone, we don’t recommend Wi-Fi pet temperature monitors for RV use. They’re just not reliable enough to protect your pets when you’re away from your rig.
Why Cellular Monitors Are Better for RVers
Cellular pet temperature monitors like the MarCELL Pro have their own built-in cell connection. That means no relying on campground Wi-Fi or your phone’s hotspot.
Yes, there’s a monthly or annual subscription fee to maintain the cellular service, and the upfront cost is higher than some alternatives — but in our opinion, it’s absolutely worth it. When it comes to your pet’s safety, reliability matters most.
It’s important to remember that even the best RV pet temperature monitors are only machines. They must be used with human common sense. Do not leave your pet inside your RV if temperatures are going to be extreme, even with a monitor. You may not have time to make it back to your pet before it gets too hot for them. Also, remember that RV pet temperature monitoring systems require you to have a working cell phone on hand and for you to be in the cellular range to receive alerts.
How the MarCELL Pro Works
The MarCELL Pro doesn’t need Wi-Fi, a phone line, or an internet connection. It uses a built-in cellular module to send data every 10 seconds, and it can instantly alert you if anything goes wrong.
Here’s what it monitors:
- Temperature & Humidity – Set your safe range, and you’ll get alerts if your RV gets too hot or too cold.
- Power Status – Know immediately if your rig loses power (which means your A/C could stop).
- Water Leaks – With the optional SPuck sensor, it can detect water from leaks or burst pipes.
This extensive range of data collection is handy for RV owners because not only will the MarCELL tell you when your ideal temperature or humidity levels have been exceeded, but it can also tell you if your RV has lost power (causing the air conditioning to stop working) or with the optional SPuck water sensor it can tell you if there is water inside your RV (useful if a pipe bursts, for example).
This pet temperature monitor will provide reliable alerts so you can immediately return to your RV to rescue your pet before the inside temperature rises to a dangerous level.
Alerts can be sent via:
- Text Message
- Phone Call
It’s important to note that if an alert is triggered because the temperature inside your RV is too hot for your pet or other conditions are beyond your safe ranges, an alert will be sent instantly and automatically to your mobile device via email, text message, or a phone call. The MarCELL Pro checks conditions every 10 seconds.
That’s peace of mind you can carry in your pocket.

Traveling with pets is so much fun and a great way to keep the family together on long road trips in your RV. But of course, there are times when taking your dog or cat with you just isn’t possible, and you have to leave them behind in the RV.
Even on mild days, an RV can heat up dangerously fast or lose heat rapidly in the cold. Having the MarCELL Pro has allowed us to leave Sierra behind when necessary, without constant worry.
There have been a couple of times while out and about that we’ve lost power. The MarCELL Pro lets us know right away. Fortunately, power came back before things got dangerous — but if it hadn’t, we were ready to head back and take action.
We’ve come to rely on this system. In fact, we won’t leave our dog alone in the RV without it.
