Overview

Mini 1PM is designed for shallow wall boxes where larger relays and smart switches don’t fit. Wiring is simple, as the relay only requires neutral, line, load, and an input from the switch. The relay can also be installed at the fixture for direct control, though using a switch in this scenario will disable the relay. If the circuit uses a switch loop, the switch can still be used as an input when the relay is wired at the fixture.and load.

Note

If you’re not experienced with electrical wiring, you should work with a licensed electrician to complete this solution.

Instructions

  1. Turn off the breaker controlling this lighting circuitoutlet.

  2. Use a voltage detector to make sure the circuit is not energized.

  3. Connect a neutral wire from the load center (breaker panel) to Mini 1PM’s N terminal.

  4. Connect line (hot) a neutral wire from the load center (breaker panel) to Mini 1PM’s L terminalthe outlet’s silver screw.

  5. Connect line (hot) from the load center (breaker panel) to the light switch’s bottom pole.Connect the light switch’s top pole to Mini 1PM’s SW L terminal.

  6. Connect load (the wire going to your light fixtureoutlet’s brass screw) to Mini 1PM’s O terminal.

Top Use Cases for Mini 1PM Gen3

Shelly Mini 1 1PM Gen3 uses Shelly’s smallest form factor enclosure. This makes the product ideal for:

  • Shallow gang box installation

  • Power measurement

  • Switches and outlets

Note: Shelly Mini 1PM Gen3 is limited to 8 amps. It is critical to verify the total load for lighting circuits controlled by this product will not exceed the product maximum prior to installation. To determine total load of a lighting circuit, add the total draw of all bulbs used in fixtures downstream of the relayan outlet’s circuit, use a multimeter with clamp at the breaker panel, measuring the load side of the circuit’s breaker.
