A must for pets in RV
⭐️⭐️⭐️⭐️⭐️ Absolutely Love This Temperature Monitor!I can’t say enough good things about the Necto Cellular Temperature Monitor! I use it in my camper to keep an eye on the temperature for my pets, and it has given me total peace of mind. The setup was super easy, and the app works flawlessly — I get instant alerts if the temperature changes, which is so reassuring when we’re out exploring or running errands.The readings are accurate, the connection is reliable even in remote areas, and the battery life is great. It’s small, lightweight, and easy to move around if needed. Honestly, this little device has made traveling with my pets so much less stressful.If you have pets and travel in your RV or camper, this is a must-have!

This is a great way to keep track of temperature, humidity and power outages!
Very handy way to keep track of the temperature and humidity in a place that you are not at all the time. It also tells you of power problems. Very nice to know. Would have saved us a lot of money and trouble on frozen pipes with a power outage last winter. Set up was pretty easy. I think we spent more time deciding on a nickname for it than anything else.Good to keep it away from the stove where the humidity created by cooking food can make it go off when meals are cooked. You know it’s safe to call, guests are not sleeping anymore.

Excellent reliable detector, app, and cell service!
I’m a fan! Tried a temp detector some years ago and was a fail, and company went out of business. This choice, while seemingly more expensive, comes with two years of included cellular service and monitoring. That evens the overall cost. And it’s nice not to have to pay for monitoring after activation, for two years.App works flawlessly. Have been able to connect to unit for monitoring every time without an issue. And every time power is lost or reconnected, I get a signal. Multiples, push, email, and text. Same with temperature alerts, always received without issue.In my case I keep in the car, plugged into a power inverter in the cigarette lighter, and the battery keeps going until I get in car again and go. While driving the battery charges back up. And it is in the car in case I have to leave my dog in the car with the A/C on and doors locked. It’s rare but when I have to do it I want to be sure if car shuts off, or it gets too warm, I get notifications via push, text, and email. And I do getThem as car is shut off and as it gets hotter in car. It’s been perfect for timely notifications. A reliable product is priceless to me, so I make sure I have this setup and working each day by way of leaving it in the car, it’s always ready to go if I have to leave my dog in the car . Rarely, but it happens once in awhile. This is absolutely crucial for this.All of the necessary features and notifications work as they should. Had a question for tech support and a reply was received very quickly and with a knowledgeable response.Would highly recommend for anyone who needs a temperature detector with notifications and uses cellular vs. Bluetooth or WiFi. This means it works as a standalone device with no need for a WiFi connection.

Excellent setup & peace of mind!
Very easy to set up, and no need for wifi. Gives me great peace of mind to receive notification if temp / humidity isn’t within the range I specified. Both of those alerts are working well. When the reading returns to my specified range, I receive notification. I didn’t realize it also will alert if there is a power failure, which is extremely useful. Set up was so easy. I did have to turn it off and back on during setup in order for it to be recognized, but it took only a minute more and was no problem at all. Great product & service, wish I had done this year’s ago!!!

Peace of mind
Works great for our second home. We can check in to see temperature and humidity levels and are notified when the power goes out. Easy to set up.

The best RV monitor, we’ve tried others
The Necto is fantastic! We had the waggle in our van for a year and it was the bane of our existence. It would fail, the subscription rates kept changing kept changing, it had a clunky interfere. The waggle never actually gave me peace of mind when we left our dog. It was not trustworthy. The Necto however, is a godsend! This works smoothly, setup it up once (and easily) and i’ve never had an issue. It reads correctly, alerts us clearly. And no monthly payment for two years! This thing is worth every penny even though it’s more upfront. Highly recommend!

Keeps and Eye on Your Home’s Temperature for When you are Away.
I was between houses (selling/buying) and when I was away from the home I was selling, I did not want to be greeted with a broken pipe or power outage. This device did both, as long as it is plugged in. It has its own internet built in (for the first 2 years after which you must pay) and was able to send an alert to my phone if something was wrong, and I was able to monitor the temperature of my home (I kept mine in the basement as that is where the trouble would be if the furnace went out. It was a great piece of mind.The one issue was that every now and then the network for the device went down, but at the most after an hour or so it came back up, other than that, perfect!

Power monitoring
I purchased this device a few months ago. We use the device in our RV. We are able to keep our TV plugged in while in storage to keep the batteries charged and the refrigerator running. The monitor lets us know if there is a power disruption. It also monitors heat and humidity. It has worked flawless and the price with the subscription included was reasonable especially compared to other products.
