WalTech is the thermostat, so it doesn’t just tell you it’s hot. It keeps it cool.
How do I keep my pet safe in my RV?
WalTech UST 3.0 is a smart RV thermostat with Pet Mode. It watches the cabin temperature and power, alerts your phone, and runs your AC or furnace to your setting. Alerts come over Wi-Fi at no cost, or with no Wi-Fi on the optional Cellular plan.
A day at the campground.
Scroll through an afternoon with Pet Mode.
1:00 PM
96°F outside.
One AC can’t keep up with the afternoon sun. Inside creeps to 78°F. Pet Mode is watching.
1:02 PM
You tap. The bedroom AC turns on.
In a two-AC RV, the alert reaches you on the trail. One tap in the WalTech app, and the second AC kicks in.
1:30 PM
Back to 72°F.
No U-turn. You keep hiking.
4:30 PM
Home. Tails wagging.
Everyone is safe and cool. Back to vacation.
Power out?
No thermostat can run an AC without power. WalTech keeps watching on your RV’s house battery and alerts you, so you can head back or text a neighbor. To get alerts when the Wi-Fi is down too, add the optional Cellular plan.
Every co-pilot is different.
A few things pet parents learn on the road.
Frenchies, pugs and bulldogs feel the heat first. Set Pet Mode a little cooler.
Cats hide when they’re too warm, so you may not see a problem. Your phone will.
Older dogs sleep through everything. Pet Mode stays awake.
Thick coats hold heat. Keep the cabin steady.
Leave like a pro.
Five things to do before you lock the door.

What RV owners say.
I love my WalTech Smart RV Thermostat. Knowing my dogs are safe when we are away from your camper. Plus all the other great features.
Best investment I have made. Easy install. It’s nice to have the pet monitoring feature.
Plans.

The optional Smart Hub plan watches leaks, doors and tanks while you’re gone, for up to 40 sensors. It runs your automations and alerts your phone when something’s wrong. $5.99/mo billed yearly, or $7.99 month to month.
Questions.
Do pet alerts cost extra?
No. Pet alerts are free over Wi-Fi.
What if there is no campground Wi-Fi?
Add the optional Cellular plan and alerts reach your phone with no Wi-Fi. It is $7.99/mo billed yearly or $10.99 month to month.
Does it have a battery?
No. WalTech UST 3.0 runs on your RV’s 12V power and works from 7.5V to 32V, AC or DC.
Will it fit my RV?
It works with most fixed-speed RV air conditioners that use a wall thermostat, including R410A and R32 units. Check compatibility to be sure.
My AC is not compatible. Can I still use Pet Mode?
Yes. Smart Hub + Pet Monitor is the same hardware without the thermostat wiring. It sends pet alerts and connects up to 40 sensors, but it does not run your AC. See Smart Hub + Pet Monitor.
