Question about connecting 12 volt LED lights

[brumster (Paul)]

If you want them as 3 completely separate items in ST then the easiest way will be to have 3 devices. Either 3 sockets (with two additional power supplies) or 3 Fibaro relays connected in parallel to a single power supply.

The Orvibo relay will also work (I have one controlling my garage door). ST detects it and you can use the default Zigbee relay device type handler (DTH). At some point I hope to get the Orvibo working so that I can control 3 items (not just one).

Not sure how familiar you are with the IDE and custom DTH, have a read of @JDRoberts guide if needed here:

[OBSOLETE] FAQ: An Overview of Using Custom Code in SmartThings (SmartThings Classic, Groovy Code)

The original FAQ information in this thread refers to the original smartthings architecture, which was in place through the end of 2022 and a little beyond. Custom code was written in the groovy programming language and ran in the smartthings cloud. As of May 2023, you can no longer add new Groovy DTH‘s or smartapps to your smartthings account. So if you came here because of a link in an old forum thread, or on another site, I’m afraid the Groovy information is no longer usable. All of this was replaced by a new architecture. Cloud to cloud integrations use the smartthings API. Hub connected devices, mostly Zigbee and zwave, now use “Edge Drivers,” written in the LUA programming language. Here’s the official announcement on those: The process for using a custom Edge Driver in the new …

Hope that helps.
