Guardian by Elexa is a standalone leak and flood detection/prevention system that installs with no tools or plumber. Guardian currently consists of two pieces of hardware–the Valve Controller and the Leak Detector.

The Valve Controller installs on top of your existing water main valve and can be used with any quarter-turn ball valve with a pipe diameter of ½” to 1-¼”. Each Leak Detector is battery powered and communicates wirelessly with the Valve Controller on a local 915 MHz RF network with a maximum range of 1000 ft. They can be placed near plumbing fixtures and appliances to monitor for water leaks.

The moment water is detected by any of your devices, the Valve Controller will shut off your water main and you are notified immediately!

App Features Include:
• Setup and control multiple Valve Controllers and Leak Detectors
• Organize your devices
• Event history
• Mobile notifications

Valve Controller Features Include:
• Simple DIY installation without tools or plumber
• Support for 50+ connected sensors
• No motor calibration needed
• Optional battery backup
• Leak detection w/ optional remote probe

Leak Detector Features Include:
• Water detection
• Temperature reporting
• Movement/tamper detection
• Optional remote probe
• Over 1000 ft. of wireless range

Cannot connect brand new unit

Downloaded new app.
Tried to connect unit with pin
Cannot join hotspot.
Tried multiple times.
Unplugged unit 3 times and waited 30 seconds.
Same result.

My phone is running on the newest update.

Biggest waste of money ever, old app crashed every time or left me at a blank white page.

Tech support is useless, same thing I read on their forums I completed before calling.

No I don't have a Motorola modem.

Maybe fix the bugs with your lame app

$300 unit that doesn’t do anything but grips to a pipe like an owl.

Developer Response ,

Hi, sorry to hear about the issues you encountered. If you have not already, please open a ticket with our support at https://getguardian.zendesk.com/hc/en-us/requests/new so we can solve this for you.

In the meantime, your problem may benefit from a factory reset of your Valve Controller (hold the gray button for 35 seconds and release). After this, confirm you see the device as a nearby Wi-Fi network as "Guardian-XXXX" and try the add process again.
