So far so good! Love the security when leaving my dogs in the Rv!
Works great. I set the temp. and humidity alert and received alerts when the temp. was reached. Also received an alert when the power went off. I also like the fact that I can check the rv temperature anytime with the app.
Everything working great!
Works great!
It give me comfort to know that the dogs will be ok when we have to be away from the RV.
One day in August 2026 in Las Vegas, our breaker tripped and turned off the power. It was 106° outside and we were 5 minutes away. Luckily, we did have cameras inside and they went offline, so we rushed home. We weren't gone very long so there was no harm done. We stayed home with the dogs and the next day, the breaker tripped 3x, each time requiring us to flip it back on to get the ac back. That was it for us. We hightailed it to Denver and I ordered a Necto based on my fb group recommendations. WOW. What a literal lifesaver. Now we get text AND email alerts when the temperature dips below our threshold or when the power goes out (at which time it switches to battery power). I know it works bc it notifies us when we unplug and hit the road. I wish I had discovered it sooner, but at least I did in the nick of time!
We love our necto. For the first time we can play with our trailer and get the humidity perfect. People would say leave your cabinets open and do this and do that. We got temperature gauges and places them all over the trailer then tried the damprid, then purchased a dehumidifier had a fan running. Did our own tests and learned that the fan makes the humidity higher. That opening the doors in the trailer do nothing for inside all the cabinets or pantry. We can set the alerts and it's crazy awesome. We now have peace knowing that our trailer's humidity is very low and we can check it during the day or wait for the weekly report. It shows in the report every 15 minutes and we can see what works and what doesn't. When we go camping we can use it for our dogs if we leave them in the trailer. The price is awesome, like $7/month. Can't beat that anywhere else. It's not owned by corrupt corporations like China or BR, SS or VG. They are privately owned and operated and they respond promptly to emails or phone calls. Highly recommend this company.
Works good and gave us Peace of mind! Knowing the temperature and power status of our camper with pets in it while away from the camper
Received order in a timely manner and installation was quick and simple. I like that you can calibrate the unit to actual temperature.
Worked great for dogs to make sure they were cool in van and air conditioner was still working.
It keeps my dogs safe in the camper while I'm away by reporting humidity and temperature. Takes stress off me.
Great for keeping pets safe and no WiFi
Has worked well, but need to get out and back into the program for the temperature to update. It’s too bad that the temperature doesn’t update on some reasonable schedule.
Very easy to set up and the app is easy to use. We use ours in our camper to protect our dogs, and it’s good to know they’re safe while we are away.
Works as advertised
Easy setup. Does the job!
Very happy with this monitor. I feel so much better leaving my dogs in our travel trailer knowing I can monitor the temperature, especially on really hot days. I can rush back should a problem be detected.
Easy to set up. Plug in, download the app, and your off to monitoring the temperature and humidity.
Excellent! Works so much better than the competition and total cost of ownership is less $
Good
Works great, love the instant alerts, and that it has a backup battery incase of power outage. Gives me peace of mind while leaving my dog in my RV.
Perfect for our little pub who loves to travel with us in our RV.
Fantastic product! It does exactly what it supposed to do and does it good. I use it in the RV and vehicle to keep our dog safe. It’s simple to setup and use. The battery life is good, readings are accurate and the alerts are prompt. I really like that it came with 2yrs of monitoring so I don’t have another stupid subscription.
Our unit works GREAT! It’s not uncommon for us to leave our pets in our camper when we camp. I wanted to ensure their safety and have peace of mind. The Necto unit is perfect for monitoring conditions in our camper!
Peace of mind!! We camp a lot and have dogs. One time after a storm our AC did not reset. Fortunately it was not 99 degrees outside and we arrived shortly after it went out. Now when we go out I find myself checking the temp and humidity frequently to make sure my babies are safe. Thank you Necto!!!!
Seems to work good so far!
Works as advertised...makes me feel less nervous leaving my pup alone in the rv...thanks!
Switched from another temperature monitor and it has been great so far. Super easy to set up and very responsive. Great product with a great price!
I bought the temperature monitor to put in my trailer when my dogs are in there. I had an experience for my generator cut off and it got very hot in my trailer. This is just awesome!
I bought the Necto to use in the motorhome. It is a very nice feature to turn it off when I am not using it. Pricing is reasonable. As of right now, I have not needed it, but will soon. It’s pretty straight forward.
We just bought the device for our RV. It seems to be working perfectly so far.
Excellent! Works like a charm. Very easy to connect. We had a temp stick and it was always a pain trying to connect on Wi-Fi. We love the Necto
Fast delivery. Easy activation. Anxious to take it on a trips
Love it
Works awesome! It’s better than expected!
Works really well
So far I am really liking the sensor. I like that I can be anywhere away from the sensor and still receive updates and can look at what temperature/humidity it is. I use it for my car as I travel with dogs a lot. This helps me make sure the car is temperature controlled and monitored for keeping pets safe.
Love, love this!
This little box has been a game changer! It works efficiently and it set itself up as soon as I hooked it up! I keep this in my house to monitor the temperature due to having a Boston and a Frenchie. I have one camera that also shows an inside temperature but this thing is great because it can go with us when we travel! I plan to take it to all the rentals along with a separate camera. I love that this came with 2 yrs of a subscription. I had looked at waggle but they were just too expensive. I’m very very happy with my purchase! Thanks again Necto!
It gives me such a piece of mind to know what temperature out camper is at all the time. Even when we aren’t there.
