G1 WiFi Gateway - Temperature and Humidity Sensor Gateway for Data/Alerts from Anywhere via Internet - No Monthly Fee, Unlimited History, Developed/Supported/Hosted in USA

I have previously ordered a wifi temperature sensor from Govee. It was a nice product with amazing analytics but failed to provide email alerts. I could only get alerts when the app was active and only in a transient form. They came and went and I could not find them after the fact in the iPhone notification log. Unless you happen to be looking at your iPhone at right time, there would be no traces of temperature limit violation alerts. Unfortunately, I had to return the Govee product back to Amazon.With some understandable skepticism I ordered the SensorPush gateway and two temperature/humidity sensors. The setup was easy. User instructions were probably the most clear and intuitive that I have seen in a long time. Even the guide itself was printed in relatively large and clear print, which makes a difference for an old person like me.I took me all of 3 minutes to plug the gateway, pair it with iPhone via Bluetooth and then connect to my home wifi. Adding each sensor was another 30-second exercise.Then I started my testing. Notifications for high temperature limit violations were issued very quickly, essentially in real time. I had a little more problem with the low limit thresholds. I put sensors in a fridge a little to far from the gateway and the device kept giving me 65F for a few minutes. I finally understood that the sensor was not communicating with the gateway so no data updates were provided. I took a cold sensor out of the freezer and almost immediately the temperature reading in the app got updated to 20F and I got the alarm I was waiting for.I was able to play around with the calibration and it worked well. Once you adjust the temperature offset, you will be getting accurate readings. I have precise thermometers at home and was able to calibrate SensorPush sensors right on the money.The app, by the way, is so simple it is amazing. Probably the most intuitive I have seen in a long time. As a software developer myself, I was impressed. The cloud service comes free with the device purchase. Several other monitoring services wanted to charge me a fixed price for measurement hardware (more than SensorPush) plus a nice monthly/quarterly fee.Everything was going well except for email notifications. I just could not get them. I ran many tests with various heat sources and proved to myself that this system will produce notifications and will do that quickly and reliably. But without email alerts it was a no-go for me.By the way, you cannot set up the email notifications in the app. You have to go on the SensorPush web site and login into your account to do it. SensorPush is an excellent product and my only recommendation would be to add the email activation directly in the mobile app.The absence of email alerts was disappointing. I submitted a problem report form directly in the app on Sunday in the hope of getting a reply in the next 48 hours. In about 30 minutes I got a confirmation email that my report was received and someone is looking at it. The email asked me to provide more information if I had anything to add. I replied that I wanted to confirm that I did get an email from SensorPush and would like to get similar emails for actual alerts.In a couple of hours I received email from one of the company founders, Nick, who let me know that he examined my account and everything looked good to him. He said that he would be asking his cloud team to dig into the problem. In the meantime, he advised me to check my spam folder.Sure enough, I found all email alerts in the Gmail spam folder. I should have checked it before firing off a complaint. I immediately sent email to Nick thanking him for a quick response and telling him that he was correct in his suspicion.I have retested both sensors under a variety of conditions. I probably did more testing than SensorPush QA people. I confirmed that email alerts are issued reliably and quickly and that notifications are popping up in the iPhone notification log even if the app itself is not active.This is an amazing device with hardware being nicely integrated with the server and app software. I will be getting a second gateway and additional sensors for our other house.

Excellent products. So simple to use and set up. I own a two story radiator shop right next to my house and last winter the garage door opener erroneously activated in the middle of the night, when the temperature was near zero and quite windy. Even though I live right next door, I had no Idea the door had opened. It caused many split pipes and flooded the entire upper floor with 1" of ice. Also, I use a portable fuel oil (salamander type) heater to keep the shop above freezing as temperatures here in central NY go below freezing for weeks or months in a row. In the past I have had problems keeping it running 24/7 especially since I don't work on weekends and don't check it directly until Monday morning. It sometimes runs out of fuel and I don't catch it or if it fails to fire up properly the first time, it has to be manually cycled to get it to light. So I decided to monitor the temperature more closely and needed a way to have it notify me wherever I am that it needs attention quick. This winter I purchased a cheap temperature and humidity sensor that utilizes Bluetooth technology. But it wasn't able to lock on from the shop to the house and thus wasn't reliable enough. So after some research I found these SensorPush products that use a wireless gateway and multiple sensors to send a signal directly to my cell phone and will alarm me if any sensor is out of my preselected parameters. I bought two sensors, one for upstairs and one for downstairs. This system works fantastically! I can be out of town and check to see what the temperature and humidity is in my shop any time 24/7. I have it set to alarm if the temperature should drop below 38 degrees. I also set it up to notify me if it goes above 75 degrees in case I leave my boil out tank running by accident, which I have done since purchasing this system and the alarm did notify me in the middle of the night. So I am thrilled to have this ability. The cost was higher than I would have liked to spend but I figure it will pay for itself if it saves me from freezing pipes or boiling my tank dry. I also purchased a new portable heater to use as a back up and they are both on thermostats that kick them on and off at a preset temperatures. So far this winter I have had no problems keeping the shop warm, but more importantly, keeping it from freezing. Great products, I will be soon buy several more sensors to use here and there as I keep thinking of interesting new ways to use them. I adjusted my refrigerator and freezer to optimum temps with them and I'd like to set one up outside to monitor in the summer.
