  • If you have an Eero you can set this up easily!
This leak detector works great and is easy to set up. I read reviews here that said people were having trouble setting this up because their router was a 5 GHz router. It is true, this device only works on 2.4 GHz. I have an Eero set up. My eero works on both 2.4 AND 5 GHz. You can set this device up if you have an eero. Here is how you do it: 1. Go to your eero app settings. 2. Near the bottom you will see “troubleshooting. “ Press on troubleshooting. 3. At the top of troubleshooting you will see, “my device won’t connect. “ Press this. 4. Now you will see, “my device is 2.4 GHz only. “. Press this. 5. At the bottom you will see a blue tab that says “temporarily pause 5 GHz.” Press this. You can now easily install your Mobi devices. When you are finished installing them, go back and press “cancel.” If you forget to press cancel, don’t worry, it is on a 15 minute timer, and at the end of 15 minutes your eero will revert back to both 2.4 and 5 GHz. I only have the Mobi water/leak detectors, but I assume this will work on all Mobi products, if you have an Eero. Hope this helps. ... show more

  • Works as expected once you clear the installation hurdles
The unit will only work on a 2.4GHz WiFi network. My network uses one SSID and auto-senses and uses the best network (2.4 or 5 GHz) based on the distance from the router and the device. The sensor would not configure in this config. I had to create a separate 2.4GHz network and connect my iPhone to this network to see and configure the sensor. After configuring the sensor I was able to move my phone back to my normal network. The sensor does send alerts to my phone in this config. ... show more

  • Sensor works but software is terrible
Sensor seems to work fine but setup was very difficult. Instructions suggested I download the Mobi Smart app for setup but I was simply unable to link the sensor to my wifi network with that app. Before returning the sensor I tried to link it with my existing Smart Life app and it connected on the first attempt. The Mobi app seems to be useless and not needed! ... show more

  • Need to know and need to test
I tested 2 devices: 1. No alert when batteries are removed for hours. APP shows 100% battery. 2. No alert when sensor operates at half voltage. APP shows 100% battery. Sensor connects to network but does not respond to water. 3. No indication that device is offline and not working after batteries were removed, or at half voltage. 4. No network status to indicate device is offline. Sensor appears to be online when it is not. 5. Alerts Did Work. Devices detected water and sent alerts to phone when phone was NOT connected to wifi network. Had to uninstall and reinstall the APP. I was preparing to return the devices but in my research, i could not find one that appears any better. Will test on a regular basis. ... show more

  • Awesome product
What is most amazing about this sensor is the high quality for the price. Almost unhead of to get a WiFi sensor of any kind under $10. No hub is needed - just a decent wifi signal; not even a great signal is needed to connect - just decent. Also, very easy to set up with the MOBI app. So; for 10 bucks you get a hub less sensor that will connect easily to even to a weak wifi signal, has a great app to work with, and gives you the piece of mind to catch that hot water tank leak before it destroys your house. Kinda no brainer. ... show more

  • No alert if link is broken
This leak detector is easy to install and actually works. The best part is you don't have to be on the same wifi to receive alerts. You can be anywhere you have an internet connection. One problem is it doesn't alert you if the communication link is broken. It would be great if it alerted that the comm link is not working. It would be useful if it displayed the last time it tested the battery. ... show more

  • Saved me a couple times already!
I have this device in my basement for the sump pump. Its a ways away from my router and still receives a signal just fine. The device itself beeps as well as sends a notification to your device. It has already saved my basement from a flood twice... I would recommend this to anyone. App setup was slightly more challenging than I preferred... but I got through it. ... show more
