The RSP-mini: The In-Suite Electric Sub-Meter That Hides in Plain Sight
Published August 9, 2025
Meet the electrical smart meter you could mistake for a thermostat. The In-Suite Residential Single Point (RSP) mini by Sieco-Tech, or RSP-mini, brings full sub-metering power to any apartment with the most discrete, low-profile design available, at a very affordable price point.
Support accurate, real-time tenant energy data without invasive wall installation boxes and without compromising meter performance.
The Electric Sub-Meter Designed for Suites
Most electric sub-meters available for residential building projects were designed for industrial applications.
They have to be mounted on DIN rails, which requires cutting out a 12-by-12-inch hole in the apartment’s wall and installing a steel box. You’re left with an ugly gray box that, at best, may get framed with trim board. Plus, the meter is left hidden behind a locked cover.
In-Suite Design
The RSP-mini is different.
It’s designed to live inside an apartment and looks no different from any other standard security system panel, thermostat or wall sensor.
You knock a small hole for wires, mount the meter base with two screws, and slide on the meter.
The unit’s low-profile design covers the cut neatly. No big boxes and no extra trim or patchwork.
And the meter display is easily viewed, meaning anyone can read their power use at any time.
RSP-mini is Made to Measure, Built by Innovation
Every inch of the RSP-mini is engineered with a vision to create the most practical, non-invasive sub-meter available for multi-family residential buildings, condominiums, and apartments.
• Smallest Complete Package
The RSP-mini is the smallest full-meter model for apartments. Every part fits inside one slim console.
• Very Low-Cost Solution
Ease of installation for the RSP-mini slashes labor costs during deployment, while its modular design and replaceable components enable easy field maintenance.
Over the life of the meter, expect to spend less than half of what you would with other meter alternatives.
• Secured, Attractive Design
The RSP-mini was created for living spaces and sits clean on the wall. Physical seals and a hidden Tamper switch keep the meter safe.
• Built-In Communications
Lynked RF-mesh comes built-in for the RSP-mini, meaning it can start sending data as soon as it’s commissioned. If the project requires power-line networking, Sieco-Tech offers a G3-PLC upgrade model.
• Fast Installation & Serviceability
The RSP-mini's design supports quick installation and efficient field service, while securing all sensitive components with appropriate meteorology seals.
• Optional Breaker Compartment
An optional UL 489 breaker snaps into the bottom slot. It provides overcurrent protection to the meter wires to meet any electrical code concerns.
Keep Operations Fast, Efficient
If or when fieldwork is required, the RSP-mini is designed to keep maintenance quick and clean.
The meter head pops off with a firm pull, and every wire can be released by pushing on its block. A technician can test or swap the meter in about five minutes while the suite stays powered, saving you labor costs and time compared to scheduling an electrician.
Unlike other meter designs, service work and Measurement Canada accuracy reverification for the RSP-mini can be performed while leaving metrology and terminal seals intact. The outer tag breaks for maintenance, while the S-E-02 accuracy seal stays locked in place.
Minimalism Without Compromising Performance
Even with the RSP-mini's compact size and residential-friendly design, the meter meets the strictest performance standards in North America.
Dual Market Flexibility
- Measurement Canada Approved — The RSP-mini has passed Measurement Canada’s full type-approval process and has been rigorously tested and confirmed to perform with an accuracy of within 0.5 percent across voltage swings, power-factor shifts, and temperature changes.
- ANSI C12.20 Certified — Independently lab-tested and certified for revenue billing in the United States under the American National Standards Institute’s C12.20 standard.
- Deployable in Any Region and Building — The RSP-mini is proven to perform in any location, climate or building composition. Readings continue to hold accuracy between –25 °C and +53 °C to support buildings in any region. Meanwhile, Lynked RF mesh and G3-PLC capabilities mean you can securely transmit data through concrete, brick, steel walls, or power lines.
