⚠ Still relying on WiFi-only tank alarms?
A Smarter Alternative to the
SJE Rhombus WiFi Alarm.
The SJE Rhombus Xpert Alert® WiFi alarm only works where you have reliable WiFi. Rivio uses built-in cellular (LTE) connectivity to deliver real-time tank levels, smart alerts, and automated pump scheduling — even in remote locations with no internet.
🚨
WiFi alarms fail when your router goes down, during power outages, or at remote sites with no internet. Rivio's cellular connection keeps you monitoring 24/7.
What Is the SJE Rhombus Xpert Alert® WiFi?
The Xpert Alert® WiFi is an indoor alarm system that sends text and email alerts over a WiFi or Ethernet connection. Here's what it offers — and where it falls short.
📶
WiFi-Dependent Connectivity
Requires a working WiFi router or Ethernet cable. If your internet goes down, your alerts stop. No cellular fallback.
2️⃣
2 Alarm Inputs Only
Monitors up to 2 float switches. Operators managing multiple tanks or multi-point monitoring need additional alarm units.
📧
Basic Text/Email Alerts
Sends notifications to up to 4 contacts. No dashboard, no trend data, no automated dispatch or pump scheduling.
🏠
Indoor Use Only (NEMA 1)
Rated for indoor environments only. Remote or outdoor tank sites require weatherproof enclosures that the Xpert Alert doesn't provide.
