UK Light switches – My experiences (2020)

No, I have never heard of webcore pistons.

If the official smart lighting feature is available in your country, try that one. It works with older DTHs that don’t always work in the new V3 app, and specifically it handles buttons in the old way.

Steps one through four in the following FAQ have screenshots showing you how to find the smart lighting feature. You can ignore the rest of the FAQ. (The topic title is a clickable link)

FAQ: create a virtual three-way using the “mirror“ feature of SmartLighting [NEEDS UPDATING]

You can have one device turn on when another device turns on, and turn off when that device turns off, by using the “mirror“ feature of smart lighting. You can also keep the devices in sync if you want by creating two of these automations, One with switch A as the trigger and switch B as the target and another with switch B as the trigger and switch A as the target. ( there are a few switches which get confused by this and go into a loop if you use two automations with mirroring, but most switches can handle it.) Here are the steps. choose the three horizontal line menu icon in the upper left of the screen, not the + in the upper right. [image] choose smartapps from the pop-up menu. you should now see “smartlighting“ on the list of smart apps for your account. If you do not se…

If that doesn’t work, webcore is a community created rules engine for smartthings. (A “piston“ is what Webcore calls its automations.) Very powerful, but also can be a lot of work to set up. Here’s the FAQ on that:

FAQ: What is WebCoRE? (And what was CoRE?)

CoRE (now WebCore) is a very powerful community – created rules engine for SmartThings. It allows you to set up stacked conditionals like “If A then B but only while C and not if D.” Setting it up can be quite complex, but there are many community members who will be glad to help you. For example, here is a piston that one member created to notify him if the dog had already been fed twice that day and he picked up the dog bowl for a third time. He needed this because he has a large family and people didn’t always remember whose turn it was to feed the dog. [image] The original version of CoRE Has now been replaced by a new version, WebCoRE, which moves the data entry to a web interface. This allows for flexibility and an architecture that requires more memory than is av…
