Smart Independent Receptacles with Shelly 2.5

Last week, I placed my first order from and today, I did a fun “quarantine project,” setting up independent receptacles on an electrical outlet in my den. The best part? I finished the project in less than 20 minutes!

This install is a little different than the normal Shelly-powered outlet, but uses typical materials. You’ll want a standard or Decora style electrical outlet, 14 gauge stranded wire (black and white) to make jumpers, 1510 ferrules, and M6 forked Stacon connectors. Don’t forget a Shelly 2.5

Please note – if you’re the load for both relays (one relay to each receptacle) combined is greater than 16 amps, you should connect both L terminals to incoming line – the maximum rating for each terminal is 16 amps!

It doesn’t matter which style outlet you pick, as both styles have a breakaway tab that you can remove to separate the two receptacles.

Break the tab between the brass screws – this is for the incoming line. If you’re wiring both receptacles on the same circuit breaker, there’s no need to break the tab for neutral, just the tab for line.

Here, I’ve added all the jumpers needed for the Shelly 2.5 – I could have connected L directly to the incoming hot lead in the box, but using stranded wire and connecting via a Wago connector gives me a lot more flexibility when it is time to stuff everything back into the gang box!

Here’s the wiring layout. Note that I have Stacon connectors for every wire end that will connect to terminals on the outlet, ferrules for every wire end that will insert into the Shelly 2.5.

I like to bench test smart home modules before installing them in the wall. It lets me make sure that everything works, set up the device, upgrade firmware, and assign a static IP before I move the first stick of furniture.

Here, I have the Shelly 2.5 and new outlet connected to the existing wiring and ready to seat in the gang box.

Everything tucked in easily, plenty of room to spare.
