Is there a way to create a test device that I can connect an INSTEON switch wiring to so that I can plug it in to simulate being installed and then be able to see it the admin console?

absolutely..

Unfortunately I am not at home so I cant send a picture, but essentially I rigged up on a piece of wood, two alligator clips that go to a mechanical switch which then goes to a normal plug.

I can plug this into any outlet, hook my new Insteon switch up via the alligator clips and then when ready, flip the mechanical switch to energies the new Insteon switch. Then I force a reset / default settings to erase anything in the switch and then add it to my Eisy. I usually just use a temp name if it's a replacement switch.

Then in the AC, I do a replace switch on the old one and choose the temp name. Once the Eisy is happy, then I de-energize the new Insteon switch, disconnect and install it.

Works great and saves a lot of headaches.

Every single Insteon switch that I installed was first address linked by connecting it to a simple lamp cord with two wire nuts, and plugged in right next to my PC where I use Admin Console. All my ZWave locks were also first addressed here. After that I made my own little test setup for further learning and testing, as pictured below. When I mention my "test lab", this is it. The switches are a dimmer and relay switch. The light bulb socket is hardwired to the input power, and used for trying out smart bulbs (there's a Nanoleaf Matter bulb in it). The wall socket on the right currently has a IOLinc in it, and an old Leviton ZWave lamp module plugged into that. The other socket has the power supply for one of my two test Polisys on the left, with a ZMatter dongle on top in my homemade enclosure. You can also see a keypadlinc in a tabletop enclosure. That's the best way to try things out and commission new stuff!

Here'e how I do it:

Exactly what I use.

@MrBill is that something you made or bought? I assume the devices on the ends are simple connects for the wires on the INSTEON switches - correct?

@Kentinada Those are known as "wago" connectors and are available at may typical home improvement stores. Otherwise, cut the end from an extension cord and add the connectors.

Very common item to buy. I have several for my testing. Amazon.com: EP 2 Pack 3 ft 14/3C SJTW Appliance and Power Tool Cord, 14 Gauge 3 Prong Heavy Duty Replacement Power Supply Cord Cable, 110V 115V 120V AC Pigtail, 15A, 1875w : Tools & Home Improvement

I did the same as what Mr Bill is doing. But for safety added a WAGO on the Insteon modules RED wire so it could not touch anything.

I have also cut a 3 conductor extension cord in half and was also connecting the socket end to the setup. So a load could be added to see how it controlled a load. WAGO Lever nuts come in 2,3 and 5 position sizes so connecting both ends of an extension cord can be done.

Actually I don’t even use Wago’s. That picture is one that’s been passed around this forum for years. I use Ideal Tan Twister wire nuts exclusively (for 12&14 ga wire). And like @Brian H I have a female extension cord end and a rubber pigtail lamp socket handy too, just wire up whichever is needed.

Other manufacturers also make similar devices to the Wago and should work fine.
