Smart Lighting unreliable

[jlv]

Smart Lighting only runs local if it is working with locally-running devices, and even then there are still caveats. This is a good summary:

SmartLighting App in SmartThings saying it's not local, I thought it was?

Smartlighting Automations are local ONLY if everything in the chain is local (usually the culprit is the device handler) AND if you don’t use an advanced calculation in the automation that would make it run in the cloud. (For instance, if you’re turning on or off, setting values or colors you should be fine, but say if you wanted something to fire on a recurring basis at Sunset, your hub needs to be online at the time it calculates sunset for TOMORROW’s trigger…) So like I said the DTH is usually the culprit. to get local ops on your devices. The device connectivity must SUPPORT hub direct connect (Meaning Zwave or Zigbee only) The device must support one of the default SmartThings provided device types (ONLY default DTHs are eligible to even run locally - so NO custom DTHs) The Device…

Its best to check in the IDE to see if the rule is indeed local.
