You want your RV to feel right without messing with a bunch of controls. This hub keeps everything working together, from temps to lights and sensors, so comfort stays where you set it and you can focus on the day, not your pets or your RV.
Most RVs scatter control across switches and pads that never quite work in sync. This upgrade replaces that hunt with one place to manage heat, cool, fans, lights, outlets, and sensors. You can adjust everything from the wall or your phone, whether you are inside the rig or out exploring for the day. It also works with select smart accessories, so you can bring more of your setup into one system without adding complexity. Zones follow the plan you set so the cabin feels the way you want it to without extra steps.
This system is not limited to heating and cooling. It can connect with select smart accessories to give you more control across your RV. Pair a Mopeka sensor to check tank levels from the screen, add a smart plug to control everyday devices, or install a relay behind a switch for built-in control of lights and outlets. You can also monitor temperature and humidity with a wireless sensor, all from the same interface.
If you camp with pets, you know the small worry that follows you when you close the door and head out for the day. This system keeps an eye on temperature inside the rig and alerts you if it moves outside the safe range you set. You can adjust the cabin from anywhere so the space stays comfortable until you return. It helps you stay present for the good parts of the trip while knowing your pets are safe.
You keep the HVAC components you already trust. Coleman-Mach, Dometic, Furrion, and most common RV systems work with this controller. Installation is plug-and-play so you get modern, unified control without replacing equipment that still has plenty of life left.
RV travel doesn't always come with WiFi or the perfect signal, but that shouldn't keep you from staying in control. This thermostat uses WiFi and Bluetooth when they're available, and switches to its built-in cellular connection when they're not. The system stays reachable so you can check cabin conditions and get temperature alerts for your pets from almost anywhere. Cellular service plans are available through the manufacturer if you want coverage beyond campground networks.
Note: Not compatible with R32 air conditioning systems.

Ratings & Reviews
Etrailer did a great job shipping it out. USPS however took over 2 weeks to deliver the item. It sat in a warehouse for a week twice. The item finally arrived in good condition. I just purchased another item from you and hopefully will arrive a little sooner.
The installation instructions were extremely poor. The Google Docs guide only included a blurry wiring photo with no clear explanation of which ports on the Waltech the wires should connect to. The wire colors in the guide also did not match the wire colors on my old thermostat, which made the process even more confusing.
To make matters worse, there was no text explaining which numbered terminals on the back of the wall plate to use—just a blurry picture where the numbers were hard to make out. At this price point, I expected much clearer and more detailed instructions.
The waltech thermostat is working as expected. I am disappointed at the instructions are not understanding.
To explain more on instructions, wiring and mounting is well covered. But unless you are an experienced IT person good luck. Last comment. The worst part , you are instructed to go to Facebook for help.

Thank you for your review Monty. Sorry to hear the Smart RV controller did not work with your Dometic CCC 5 button thermostat system. I do see manufacturer notes stating this if your RV is equipped with an R32 system, the controller will not function properly. I can check compatibility for you if you'd like to reply back with the model of Dometic A/C you have.

Thanks for taking the time to leave such detailed feedback. I'm sorry to hear the installation instructions made the process more frustrating than it should have been. I really appreciate you pointing out where the guide fell short, especially with the wiring diagram and terminal identification. Feedback like yours is valuable. Were you able to get the unit fully installed?
