Tell us what you need watched. We’ll take it from there.

Sentrelisn’t self-serve. A person from our team sets your workspace up, connects your first gateway with you, and stays on the line until you can see your equipment. Start by telling us which of these you are.

We reply to every inquiry within one business day. Already a customer? Sign in.

What is this about?

Pick one. It decides who reads this first.

Rather not use a form?

Before you write

The things people ask first.

Because the first hour matters more than the signup form. Sentrel reads from real equipment, so someone from our team walks the first gateway connection with you and confirms your readings are right before you rely on them. That is not something a self-serve form can do, so we don't pretend otherwise.

A person reads it, not a routing bot. You get a reply within one business day, usually with a couple of specific questions about your equipment so the demo we show you is your plant, not a generic one.

Yes. Sentrel is multi-tenant and white-label from the ground up. Your customers see your name, your colors and your domain; you keep the relationship and the recurring revenue. Choose "White-label or reseller" above and tell us what you sell today.

No. That is the point. Sentrel talks Modbus, OPC-UA and Siemens S7 to the PLCs, meters and gateways already on your floor. Tell us what you run and we will confirm compatibility before you commit to anything.

Use "Support" above, or write to us directly. Either reaches the same inbox. Include your organization name and, if you can, the device or dashboard involved.
